So here are two questions...
1. Is there much discernable difference between a MM251 and a PM255? I ask this because I might be able to get a PM cheap relatively speaking from a vo-tech auction. I have used a MM251 a lot and it is a mig I have had great success with, but I haven't used the Lincoln.
2. I assume that you can run either a 251 or a 255 on a 30A dryer outlet, as long as you don't push it past the limitations of the circuit. I know to weld 1/2 inch plate with either it is going to take more power than a 30A circuit can provide,but does anyone have any experience with this (also does 208 v 220/240 matter)? I understand the equations and the way that electricity works, just not in practice. Please help dissuade my second guessing!
