  • Wire Speed

    Seems like a really basic question: All else being equal, does more wire speed mean more penetration in short circuit GMAW?

    As I understand it part of the sizzling sound is the arc making and breaking rapidly. More wire would seem to increase the time there is a short, more percent time with the current flowing, more heat.

    On the other hand, more wire is more metal to heat and melt.

    HH135, .030 solid, C25 on mild steel. I seem to be drawn to higher voltage settings (3, 4) and lower wire speeds (10-20) to get my better results. I have cut some, bent some and they don't seem too bad.

    I did experiment with Al, .030, pure agron. I was really worried about the recommended setting of max voltage and 90% wire feed ... figured I would have molten wire all over the place ... but it worked better than expected.

    Your on right track thinking increased wire speed equals more penitration as higher wire speed results in higher current/amps. Amp is unit of measure for electrical current.
