Huh, I agree that's a substantial difference, thanks for contrasting those, I had not looked at those models...another example of frustration about the actual power of welders and their model number...I hate that...if a welder puts out 130 amps (like all the 175/180 welders do), then shouldn't it HAVE to be sold as a 130amp welder? Not a "175 amp" or "180 amp" welder...and the example you showed...shouldn't that be a 160amp welder, not sold as a 210? Argh...fj40charles said:Have you compared other Hobart and Miller welders? Some of the Hobart welder use aluminum wires in the transformers. Some features may be the same, but duty cycle, internals, and accessories may not be the same.
Lets compare Hobart Ironman 210 with Millermatic 210.
Ironman 210: 150 amps at 40% duty cycle, 10 foot M10 mig gun
Millermatic 210: 160 amps at 60% duty cycle, 12 foot M25 mig gun
