the selection of wire diameter but the exact relationship depends on the material and the shielding gas. Voltage controls the profile of the weld. Inductance (in Dip Transfer) stabilises the arc and minimises spatter. Wire feed speed sets the welding current. voltage high correct low 75 0 - 80 0 450 - 550 Current Wire feed Diameter range speed ...
