I have a Miller 235 amp stick welder. This works well for all the heaver stuff including the rusty & dirty steel. I also just bought a 110 wire feed ( 90 amps )with the gas option. This relly works great for the light sheet metal stuff and work 1/4 " stock or less. So ....... I have I believe the best of two worlds. I also bought the wire welder used but the man never used it ( Still in the wrapper ) I bought it for ten cents on the dollar.
