Voltage
Increased voltage increases the arc length and gives a wider weld bead. Undercut is a
sign of too high a voltage. If short arc welding is used a higher voltage reduces the short
circuit frequency, which will give larger drops and more spatter.
Too low voltage, on the other hand, will increase the risk for stubbing and bad start
performance.
On thin plates short arc welding gives the possibility of high welding speed without
burn through. Normally the voltage here is adjusted to a low setting but only where the
short circuit frequency is still high and the arc stability good.
