ipm = inches per minute
Low voltage: wire stubs into work
High voltage: arc is unstable (spatter)
Set voltage midway between high/low voltage
Select Voltage

Voltage controls height and
width of weld bead.
Wire speed (amperage) controls weld
penetration (wire speed = burn-off rate)
. These settings are guidelines only. Material and wire type, joint design, fit-up, posi-
tion, etc. affect settings. Test welds to be sure they comply to specifications.
