I have been using Miller wire welders for 20 years. We have a 200 a 250 and a flux wire feeder on a Trailblazer 440. I recently bought a Hobart 140 and run .023 wire with straight co2 Because I don't want to take my toys out to the shop and I got tired of lugging a 200 with a big bottle to the house, even though I have a 50 amp plug. I am astounded how easy it is to weld thin stuff like
body panels. I haven't really read the book, but I would be hesitant to use it for anything over 1/4 inch. But for thin stuff, I think I could weld two tin cans together. I feel like I got the best deal on the 140 on Amazon.com
