I went into the local Miller shop and talked to the sales rep about the Miller 180 VS Hobart 210. The sale rep stated I should go with the Miller do to heavier internals. We talked about the possible need for the 210's extra power and I was told the 180 was enough to do all the jobs the 210 was capable of doing. Still think the 210 is the way to go on this, just as it was stated you can turn a 210 down if you need to, but you can't turn a 180 up...
