is it possible?

It may not have had enough voltage. Some shop machines don't put out quite enough to run them. If the voltage drops, the contactor kicks out and she no workee.

I used an '04 Trailblazer DC with a company I used to work for. In fact it was loaded in my truck at the welding supply. I've used quite a few Miller engine drive machines, and it is the only one I liked, the rest I hated. As bad as I hate to say it the TB was as good as an SA200 as far as I could tell and I learned to weld on those. Incidentally the best engine drive I ever used was a '72 SA200. It used no oil and would run 3/16 jet. I used it from '95 to '99 and they are still running it daily. But by the same token the only Hobart I ever used was smooooooth as all get out. I don't judge machines by what color they are, but how they weld, heheh. I did like that 300 amps and 100% duty cycle on the TB, and I didn't really believe that I wouldn't be able to tell when someone ran power tools while I was welding. Well the only time I ever noticed when they kicked something on it was the chopsaw. The drills and grinders I never noticed.
