at home ive got a miller 172 its a 220 machine and is good up to 5/16 I use 0.23 wire for sheetmetal and it does great. Unless they have changed them the small lincon machines have plastic parts in the drive mechanism i havent used one for mabie 5 years so the new ones may be aluminum like the millers. Just know your machines limits my welder is good to 5/16 but even being a certified welder i wouldent weld a frame with it. i see alot of people using 110 machines to do frame work and its scarry. Keep in mind a big machine like a lincon or miller 255 can weld thin guage sheet metal so you dont need two machines.
