When you say you find a pulling technique worked well with a gasless mig, was this experienced on just the single machine or several different gasless migs?
Im thinking being a cheaper mig, it would have quite basic settings, just coarse volatage and wire speed/amps not allowing you to adjust it to quite suit the application and may have produced a better weld or behaved on those limited settings better while pulling?
Sorry for the thread Hijack.
