As for my Hobart CyberTig, what I think is that it is basically their

Good chance that the inernals are the same. But putting a current
limiter (governor) on it reduces the number of warranty returns and
other bad press. Yours is a 3 phase machine which means industrial duty

the machines hot for long periods of time. Especially those on piece rates.

Thanks Roy. I think that your analysis is right. I will try to find
