Thats more than fair, I didn't want to get stuck with one that's doa. Does the Manuel specify a required alternator rating? I'll check with mobi-arc when I get back to town Monday for requirements and to make sure they can still service these in the future if needed and get back to you.

As I told Jim in a PM, and I will elaborate here: The amperage output of your alternator is going to have a similar effect as the amperage (heat) knob on your welder at home. The less amperage the cooler weld, which will affect efficiency, etc. Obviously nobody is buying these welders to assemble a steel structure, but you still want them to operate fairly well for trail fixes. That said, I feel like 150amp would be a good number with a minimum being 130. I know there are people that use these welders with an 80amp alternator that overheats and is generally a POS, and thats fine for them. However, I wouldnt do it. I would imagine mobi-arc will treat this the same as if you bought a used unit from someone else. Obviously no warranty coverage, but pay-as-you-go service and support. Of course, I have not confirmed this with them. (nor have I had any communication with them at all).

If I hadn't of just dropped money on my new bumper I would buy one... I'll keep watching and if you still have one in a couple weeks, I'll buy. If your willing to ship to a military APO that is?

Sure! I don't think shipping will be a problem, I think USPS even has a flat rate box for that!

I've had a few other questions that I figured I would answer here as well. This welder is designed to be permanently attached to the vehicle. There are ways that you could make it removable, but it somewhat troublesome and I don't feel confident in offering that ability with modifying your alternator.

Also, the welder does not act as a battery isolator (to my knowledge). As you can see in the rear-view, there are only hookups for the positive and negative from one battery. Also, I have seen many threads where the welder is run in conjunction with a battery isolator.
