Again, I've tried a search, and can't find what I need to know. My new shop has 50 Amp service (it's in a storage complex, but it does have 220 Volts). I put in a 20 Amp 220 drop so I could run my 220 Hobart Mig and my 220 air compressor (not at the same time; I'm getting old). Back in the day, I use a variety of 180 to 225 stick welders, and got to be pretty good at it. My last stick welder was a Miller 225, and I let a friend use it for the last 10-15 years. Now, he no longer needs it, and I am going to get it back. As a 225 stick welder, it needs a 50 Amp 220 circuit. I wired the drop myself with a short run of 10 Gauge wire, so I know I can probably replace the 20 Amp breaker with a 30 Amp. My question is : Is this enough current to run the 225 Miller? As I remember, I used to run about 125 Amps on the secondary when doing 1/8" to 1/4" plate. I never remember running over 200 Amps any time. I may blow a breaker once in a while, but I can live with that. On another thought, I see there are a lot of 110/220 inverter based units for less than $500 that will stick weld up to 160 Amps, plasma cut, and even Tig. Are these for real? Maybe one of these may be a better choice for me. Is the inverter technology that much better. I would be willing to wait a couple of years and go with the old Miller if there is something good coming down the line. I really feel more comfortable stick welding heavier steel, and would like to know what road to go down.
