I've been browsing around trying to gather as much info as possible regarding welders and their capabilities lately.
It seems most people for home garage or small shop use just have some of the smaller stick or mig machines.
From what I gather with the Bobcat and Trailblazer type units, they seem to have the capability of doing all types of welding instead of just 1 type..
Plus they are also generators, plasma cutters and who knows what else.
They are pretty pricey machines, I've seen them running between $2000-$4500 for some used to brand new units.
If price really wasnt an issue, would you run one of these big units, or is there a reason you wouldn't want to?
There are tons of variants of these with different options, gas, LP, diesel engines, etc...
Anyone have feedback?
I plan on doing lots of fab work, bumpers and stuff eventually.
My thoughts so far are that an engine ran welder wouldn't require me to deal with the 110/220 specific outlets, and if the machine could handle plasma cutting too and be a generator and whatever else, thats less equipment to buy seperately.
I found a local Welding Supply shop in town and went window shopping today and gathering information.
For the small difference in price, I'm thinking about going to go for these components:

Any input on the difference between the Kohler and Subaru engine options available in the welder?
They seem to be the same price with the Kohler having an extra 1hp and 500 watts of peak power.

I'm not sure I really understand. If you don't have the need for an engine driven welder, don't get one. They are more expensive, loud, require more maintanence, are larger and harder to store etc. Bottom line if you have 230v at your house, you want a 230v welder.
You really only need MIG capability, so all that TIG stuff is wasted on the home welder, especially if you are a newbie. You will want to do MIG with gas, not flux core, trust me.
If you are just building stuff for you and your trucks, then the Millermatic 180 is a great machine. It will do everything you want and isn't expensive. The Millermatic 175 was the equivalent welder until earlier this year and it's basically the same welder and used ones come up all the time.
The next step up is the Millermatic 212. I have a 210 which is the same machine just a couple of years older. This is probably the perfect welder for home and even light commercial use. It will weld up to 3/8 with no problems on one pass. It has a nice stable arc, lots of settings to dial in the way you like it to run, and is built on a heavier chassis than the 180. It comes on it's own cart that also carries the tank, so you don't have to buy that separately.
The MM251/252 is a super great machine, but you are starting to talk more $$. I'll probably get one of these eventually if I keep welding.
Just me, but I'd learn to weld before I went for an engine driven welder. They are really made for mounting on a truck and doing welding at remote sites. You will be very happy welding with a 230v machine. I would not bother with a 110v machine-not enough power for even 1/4 plate.
You definitely want a machine that runs gas-like most people I run 75%argon/25% CO2. Some run pure Co2.
Lincoln makes good stuff too. I'm a "blue" guy (Miller) but I have friends who are "red"(Lincoln) guys. It's one of those Ford vs Chevy things. Avoid Chinese crappy welders. Hobart makes good stuff a little cheaper than the big two, and uses Miller consumable parts since they are made by the same company. Esab is another company to consider.
Have fun. Get a good welding helmet that auto darkens, and about 3 good angle grinders-one with a cutting blade, one with a grinding wheel, and one with a cup brush. You'll need protective clothing, and good gloves.

Would you mind elaborating/educating on why gas and not flux core? thanx

Millermatic 180 is a great welder!....but for the $$$$ i would step up and get the Millermatic 251!!!
I love mine!
Millermatic 251 is a great shop welder......It can handle thick ga. of metal but still do any thing that you will ever want!

Sure-All welds need to be shielded when hot to avoid oxidizing and ruining the weld. With flux core, it's the molten flux that shields the weld. The flux then has to chipped off after welding. It also spatters a ton more and so there is lots more welding clean up. The one place it's good, is welding outside in the wind. There the gas gets blown off the weld and the flux still stays on the weld. I keep a roll of flux core just for that.
Gas shielding means there is no clean up and very little spatter. It makes for clean neat welding.
MIG is fairly easy to learn. TIG is more of an art. TIG is much much slower for the type of welding one does on 4x4 vehicles, but the super clean perfect symmetrical welds you see on aluminum are usually TIG welds. I'd like to be able to do it, but for the average guy building sliders and bumpers it's way too slow to be practical.
I think a MM180 would be a perfect place to start. If you find you need more power, welders are easy to sell. Like I said, I love my MM210. It has plenty of power, comes with the gas reg, was under $1500. Just understand that the welder itself is just the start. You still need the gas cylinder, helmet, clothing and some specialized tools.
Good luck.

I've got a hobart 180....the "hobby" range from miller,
only 110V and I use that messy flux core wire,,,,,,,just need chipping hammer and a wire brush.
Not much room in my garage for a bottle, so the convenience of the flux core is fine for me
I'm happy with mine and don't mind a double pass on the thicker stuff

I've got a Millermatic 251. It's great. Big enough for anything the home shop will ever do. I never considered an engiine driven unit simply because I don't need it. The multiple use machines have more to go wrong with them, which means more down time (And possibly being without any processes at all, while it's getting fixed).
Buying the individual machines lets you tailor the machine to your needs. If one goes down for some reason, you have the other machines to work with. I'm a big fan of Miller welders, but I went with a Hypertherm plasma.

Bottom line if you have 240v at your house, you want a 240v welder.
So if you didn't have the power to run a welder, are engine-drive welders a viable option or not worth the trouble? I don't have 240V and only a single 15A 120V (my garage is detached and from 1920, it's wired with knob-n-tube) and it didn't occur to me until this thread about a welder with an engine.

I have a Miller Bobcat that I run off of Propane because I use it at work inside of our freezers at times. It's 4 years old and has never given me a bit of grief. Even at -20*. I use it a lot outside to run my regular mig, and as a generator for when I am working on the jeep. I don't find it that noisy. It is mounted on wheels and is no problem to move around. I originally bought it to mount to my service truck, but changed jobs while it was in shipment. We are moving back to the farm next year and I am sure that I will us eit a lot around there as both a generator and a welder. Mine is a bobcat 225, and the only thing I dislike is the fact I did the propane. The bottle mounting spot covers where I would have mounted the bottle for the Miller S-32P mig attachment that I bought with the welder.

That isn't much garage power!
I would think an engine driven welder would be OK, but they are big and heavy and not really suited to home use. It's taking a simple thing (a welder) and making it needlessly complex. Just the expense alone would make me run away.
If you have a dryer outlet in your house, you have enough power to use a welder. If I remember right, the max draw of the MillerMatic 180 is 19 amps. So you're good on a 30 amp dryer circuit. You can always make up a HD extension cord.
I run my MM210 off a converted dryer circuit. It can draw 29 amps and I've never popped the breaker. You're almost never welding at full power. I was welding some 3/8 the other day and would estimate I was at 2/3 power.
A really good place to shope welders and look at what's out there is Indiana Oxygen(weldingsuppliesatioc) on their ebay store. Just about everyone I know got their welder from those guys and they are top notch.
More than just power, look also at duty cycle. The 212 and above are at least 60% which you will never come close to as a home welder! The 180, while a very nice machine has a 30% duty cycle, but even that is plenty for home projects. Once you start comparing specs you'll realize fast why those 110 welders at homodepot are not worth buying. Like I said, I really have enjoyed my 210 and think the added power and duty cycle was worth the price over the 180. The 250 series has a few other features that would be nice to have if cost were no object.
This is the 180:

This is the one equivalent to what I have:

And by the way, those listings are for the welder with a spool gun, which you won't need when you start out. The standard gun only will save you several hundred dollars.

I weld alot, both for work projects, and even more so on my personal projects. I just can't imagine having to fire up a gas operated unit every time I need to make a tack, or at 6am when I'm heading out on a wheeling trip :D Seems like the same argument as an vehicle based welder, while I have a Ready Welder I use for trail repairs, I can't imagine having my Cruiser idle all day while I weld something up :D I've heard people using those as their primary welder too (usually in combination with an old buzz box as the power supply).
In all my uses, I'm yet to find one where I needed a stick machine, in fact I sold my old buzz box 3-4 years ago and have never second guessed the decision... TIG, going to cost the same to use a TIG plugged into the wall as it would into a generator... which is ALOT of $$$ and alot of time invested into proper TIG welding. Again I've never really had a need for TIG, and the few times I have it was well worth the cost to pay someone that was very experienced in TIG welding (ie high dollar work that wasn't worth messing up). I learned to TIG in college while building a Mini Baja car, neat, clean, very user controlled, but not that needed for general auto fab and repair IMO. I would personally concentrate your $$$ on a MIG and a Plasma, a torch set if you don't have one too!
My father works in construction, they've put miles and miles of weld out with the engine driven units in the field (Bobcats), where its the most suitable option... Great machines no doubt. But in the shop its all 220V... if you have access to it, why not? Its cheaper to buy a decent home generator if backup power is your sole desire? You mention you don't want to deal with the hassles of "specific outlets", but there really is no hassle at all... most newer homes can be wired to the garage for 220V for a couple hundered bucks if that? If you simply don't have access to 220V I understand, but you can weld alot of simple fab stuff with a 110V welder and plasma.
I run a Millermatic 195 (220V 60% duty) for axles, bumpers, etc and a Millermatic 140 Auto-Set for sheetmetal and lighter stuff, couldn't be happier with Miller products. At the advice of my welding supply salesman (an avid wheeler too), I went with a Hypertherm for the plasma duties, its been an excellent unit too. Whereas I don't do mass production with any of my units, I'd likely be happy with any of them... at the old shop we had a Hobart 250, it was a stellar machine that saw alot of use and abuse, still working to this day. Really I don't think you can go wrong with any of the name brand units (ie Miller, Lincoln, Esab, Hobart, Hypertherm, Thermal Dynamics, etc)... but I've heard plenty of horror stories with the cheapy Lowes/Harbor Freight wire feed units? Honestly I've never tried welding with one though...

I have to agree with cruiseroutfit. I use my bobcat in the freezer a lot where I would have to stretch 300+ft of cord to run a welder. It was bought for field use on a field service truck. I have taken it in the trailer to big runs and the track where it has been a huge help running my miller 210 and other tools.
If I were going to be in my shop and not going anywhere else I would probably purchase a Miller DVI unit. I am actually in the middle of putting the money together to buy a Miller Synchrowave tig.
The bobcat is an awesome machine, but for everyday stuff at the house it is a bit much.
On another note, have your dealer show you where the battery is located. I just put a new one in mine last week and it sucked.

See, my thinking so far is that anything I buy is going to be expensive (comparing prices and specs at the store).
I'd prefer to get something that can do everything if I want to expand, especially since I'm seriously considering getting into metal fab for offroad bumpers and stuff not just for myself but as a potential business.
I certainly couldn't use a giant welder here in my current close proximity homes community, but the new house has a 2700 sq ft shop and it's 2 acres between houses out there so its a much better setup for that sort of plan.
If I have to spend a large chunk of change, I don't want to be kicking myself later because of the machine's limitations or have to deal with a short duty cycle on big projects.
I know the shop is wired for 220 (plumbed in, just needs outlets at the junction boxes) - but I'd also hate to buy a really nice welder only to find out that something in the wiring or fuse box was limiting the welders performance.
They are a bit loud (think commercial lawnmower), but couldn't I just add another muffler to tone that down if desired?
It would be a business investment for me and not breaking the bank by any means...
Id be leaving the shop with a full package deal, all the equipment, auto-darkening helmet, coat, gloves, gas, leads, trailer, etc.....everything ready to just connect up and go.
Ive checked ebay, and for the welder, plasma cutter, and mig 180, the guys rough prices were only $600 different than the IOC seller, and he seemed willing to break it all down more once I put in the order. I wouldn't mind paying a bit over ebay's prices to a local welding shop to establish a relationship with a local business either.

No one has mentioned the Millermatic DVI machines.. This is what I have, it is awesome. Sort of like a MM180 on roids. The key with strength of machines is not the peak amps but the operating amps. The mm runs at 140. My DVI at 150. A 212 at 160 or 170. Duty cycle is important too but borderline unapplicable unless you are doing major fab projects...
The DVI machine which is sort of like between a 212 and a 180 has tons of power. The big expensive machines like a 252 machine are awesome and I might someday but one I suppose (maybe) but the DVI literally does everything I need it to. It also does sheet metal and runs in 110 model, or 220 for frame fab etc. And is fairly inexpensive. It also is an amazing-welding machine, very smooth and very nice.. I also owned a Lincoln 135 machine and used Flux. Never again... For an unlimited budget I would buy a smaller machine with gas for sheet metal and thin-walled projects using .025 wire. And then a larger machine like a DVI, 212, or 252 machine for the big projects. The DVI machine will do a claimed 3/8" in a single pass and it really lets out the juice, it goes to "7" and I rarely use it past 5 or 6 even with major structural frame stuff. So I would not waste the money on something you'll seldom use, unless you have it to spend...

Mentioned the DVI in post #13...
My buddy bought one this year and it's pretty nice. He is renting an apartment while he saves for a house so the 110 capabilities work for him until he gets a house with 220. I have a 210 and a 130, and will soon have a syncrowave tig to add to the collection. Miller is definitely the way to go.
Now I just need to grab a plasma cutter.....

Personally, I usually tell people to figure out how much welder they need, then double it. But in this case, I won't say anything like that. Obviously, it is your $$$, and you are free to spend it how you want...
...but for "off road bumpers and stuff", you simply are not going to need an engine driven welder, unless you are doing field repairs....even then, there are more affordable options.
It is rare, on automotive applications, that you exceed 1/4" thickness. Truth be told....most bumpers and sliders are made from 11ga (.120"...or just a hair under 1/8"). Skid plates are typically 3/16, some as much as 1/4". Once you get thicker than that, they simply weight to much. You stiffen them up with gussets and braces, not by increasing cross section. Splash guards are rarely greater than 16 ga. All of that can be handled with a machine in the 175 range.
Duty cycle is important....as mentioned previously by someone (forgot who)...30% is acceptable for home use. 60% is acceptable for heavy home / light industrial use.
Seriously, a MM210 (or 212 now), will allow you to run 3/8" plate in a single pass....more than enough for the auto fabrication industry. In the rare occasion that you need to go thicker...run multiple passes. Personally, I have repaired as thick as 1" plate with my MM210. It wasn't fun...it wasn't pretty.....but it worked.
Unless you NEED the TIG capacity (and sometimes you do), there isn't much call for it. Personally, it is a major pain to run TIG...especially if you don't need to.

If your doing fab, then the engine driven unit is getting even more impracticle IMO, to have an engine running for hours while you mock up a bumper or sliders is grossly inefficient IMO. Sure if your doing production welding it might make sense, but not at a cost savings. You just can beat the practicality (is that a word :D) of a wall powered maching in a shop setting.
Your wouldn't be spending the money twice. Buy the Bobcat and you still have to buy a MIG, a TIG and a Plasma, it doesn't have them built in. So either you accrue the cost now, or accrue it later. The Bobcat too my knowledge doesn't have any of those features built in, the only thing it does as act as a power supply and a stick device, but again stick is kind've old-school when it comes to fab, MIG will solve all of your needs. I work with plenty of fab shops, from onesy-twosy custom stuff to fab all day everyday, I've never heard one of them wish they had a engine driven welder ;)

I appreciate the responses.
The 212 looks like the way to go for the MIG unit, I'll try to negotiate the 212 instead of the 180 into the deal since it has better thickness specs and twice the duty cycle.

I have a Miller 220v stick welder and an Ox-Acetylene rig at home, and at work, depending on the job, I have a Lincoln TIG, a Lincoln portable 220 MIG, the same Miller stick rig that I have at home, or for delicate items, I have a Ronin Laser welder. You will be better served with a rig that is a dedicated welder vs a generator/welder. If you wanted one for your Lexy, I'd recommend the Premier Power (http://www.premierpowerwelder.com/quotes/quotes.html) welder.
I've always gotten by in the bush with a rod, jumper cables, and a couple batteries though.

That is an excellent plan. Like I said, the MM210 (now the 212) is just a kick *** machine. 3/8 is easy and you rarely need to weld that thick.
Don't get too caught up in the hype. You don't need the engine driven generator if you have wall power. Your neighbors will hate you if you run the power unit, and like Kurt said, 99% of the time you are fitting or grinding, and you don't want to run the power unit the whole time. For me it's weld 10 seconds, grind for 5 minutes, weld 10 seconds, wire brush 5 minutes, grind 5 minutes, weld 10 seconds etc. With the motor unit you have to leave it on all the time. That's gonna suck!
Here is my start sequence:
1-turn on the machine
2-set the machine to the thickness being welded
3-Weld
With the units you are looking at:
1-Pull the giant beast out of it's hole, and move it close to the work
2-Crank it until start
3-Adjust the choke
4-Let it warm up
5-Set the machine for thickness
6-weld
7-turn off the machine
8-Put the giant beast back in the hole
9-Repeat 100 times every time you stop and start
10-change the oil, spark plugs, air filter
Seriously, forget the engine driven units. Just get a 212 and start welding.

I have none of these problems with my unit. It starts right up every time even after sitting for a month or 2 without being used. I can start welding pretty much right off the bat. Starting and stopping the engine for prep and stuff never causes me any problems. I use mine in pretty harsh arctic climates most of the time too.

I'm exagerrating a little bit. The point is, if you have house power, getting a motor driven welder is stupid. The noise alone is enough to say that this is a bad idea. They excell at welding where access to power is difficult. Like out in a field, on a farm, or on an un-improved job site. But for welding around the house???? Way more hassle than needed.
The interesting thing is, once you own a welder, you can't imagine how you lived without it. Mine gets pulled out every few weeks even for minor repairs.
The problem is that a welder makes you want other things, like a plasma cutter, drill press and a torch. Then you want a mill and a lathe and.......

I like em all. They all have + & - . I like stick and have booth 220 and gas. With stick you can use different rods for different aps. with out having to change mig gas or the mig gun liners. Make sure your stick mach has both ac/dc as dc will give you the flexibility you want and need. Mig is great. Have both a 110 and a 220 with lots of power. Nice and clean welds. Little to no clean up. Being able to trigger the gun is also an advantage in controlling the weld esp in an out of position weld. I use the 110 with finer wire than the 220 which lets me do lighter gage easier. Plasma is great but you must have a steady hand. You move and it cuts. Be sure to check the duty cycles. You can live with the low duty cycle on the 110 mig but will want at least 60% on the others at the highest amps or power setting you think you might use. The same goes for the plasma. Typically a 375 or 3/8 mach is good up to 3/16 and even that is at a relatively slow inches per minute. Hope this helps. If you want to come down to Tucson PM me and you can try all of them out .

There is a solution for that problem. Find something to use as a guide. Strait lines are easy....find a strait edge and go at it. I have even used a paint stir stick in a pinch. For round shapes, I have seen people use blocks of wood cut to the right radius...even old pie-pans (when the wife wasn't looking). I even know of a couple guys out in CA that will tack weld a small piece of round stock to the project, bending it into the right shape, tacking it into place, and using that as a guide. Then just break the tack welds off and grind them down....

I agree using a guide is a great idea and i use them all of the time. However the fact remains that if you wiggle the cut will wiggle right along with your wiggle. A great guide is a dry wall T-square and the 12" combo squares with the lip on one edge.

I really like my Miller DVI (Dual Voltage Input) it has 2 different plugs for 230v or 120v. The 120v option is nice for small gauge and for home projects I can drag an extension cord anywhere around the yard and weld wherever. I've welded up to 1/2" with it and as small as 16ga sheet metal (it's rated down to 22ga but I haven't tried anything that small yet).
here's the specs

I have the DVI, here's a link to the DVI2, the new version. other than cosmetic, I don't see any differences in the unit.
Input Power
* Requires 1-phase power
Rated Output
* 230 V operation: 150A at 23 VDC, 40% Duty Cycle
* 115 V operation: 90A at 18 VDC,
20% Duty Cycle
Welding Amperage Range
* 30 - 175 Amps
Wire Speed
* 50 - 700 IPM (1.3 - 17.8 m/min)
Net Weight
* 169 lb (77 kg)

I also have an Oxy/Acetyline rig for cutting and heating/forging and in a pinch, welding. A plasma can make a cleaner cut if you're steady, but a torch is a lot cheaper and can make a pretty nice cut also. If you know how to adjust it.

Re: Miller DVI... you can delete one leg from a standard 220V unit and make it a 110V unit, granted it isn't nearly as easy as the DVI but if you have an older unit its pretty cake to do.

That isn't much garage power!
I have to turn off the lights when I run any tools, it's not ideal. :-/

I think I'm going for the Miller 252 unit instead of the 180 or 212.
I am now prepared for a 3 million candlepower light attack.

Lincoln has a great little home welder called a weld pak or something like that It does pretty good for a little 120 vac welder. At work I just got a brand new Millermatic 252. I can use it on home stuff if I want - and I have. You don't have to have a ship hull welder to to good work!

Got started on my kit today....
I had to laugh when I finished and realized I welded every single inch of metal contact space....and then looked at the 4x4labs website gallery and saw that they barely weld more than a tack in a few spots...
At least now it will survive a nuclear war...

Too funny! Nice choice, makes me wish I would have waited for the new one to come out.

I also welded every inch inside and out on my bumper. On the basket I mostly welded the outsides.

Going to put my foot in my mouth on this one.... sorta.
While I still think a dedicated engine-driven power supply (ie. Bobcat) AND a Mig unit is a bit overkill... Miller just released a unit today that is the best of both worlds at a reasonable price IMO ($~2200). The key feature is that is is engine-driven, MIG setup, but can be plugged in as well :cool: So you get all the benefits of a genset, but have a regular MIG at the same time. Caveat, it is only a 180 amp machine (plenty of 99.9% of auto work IMO) and the generator is only a 5000W (again suitable for all my foreseeable needs). Another downside is the 10lb roll capacity, not a biggie IMO, I use the 10 in my 110V machine, I don't use it much but I expect a roll to last the year or more.
A local welding outfit had one on display at the offroad expo this weekend here in town, it seemed to be getting quite the buzz from folks. Big enough to use in the garage, small enough to toss on your trailer when heading to an offroad event (competitive rock-crawling comes to mind).

It's sort of funny...In 25 years of tinkering personally and professionally, I have never heard someone say "Gee, I wish I hadn't have bought such a big welder." I can't even count how many I have heard that regretted not sackin' up for a couple of hundred bucks more at purchase time to get a better rig.
