I'm in the market for a small mig welder. I had a 160 amp import that worked great for 10 years but quit on me the other day. I do mostly small stuff with the mig (big I use stick). I'm looking at Hobart & Miller both have 175amp. I see on the Miller it has infinite heat range. This seems nice but is it worth $150. more? Anybody have any comments? Thanks.
