Typical Control Settings

.
These settings are guidelines only. Material and wire type, joint design, fitup, position, shielding gas, etc. affect settings. Test welds to be sure
they comply to specifications.
Material thickness determines weld
parameters.

Recommendation
3.5 in per ampere 3.5 x 125 A = 437 ipm
2 in per ampere
1.6 in per ampere 1.6 x 125 A = 200 ipm
Low voltage: wire stubs into work
High voltage: arc is unstable (spatter)
Set voltage midway between high/low voltage
Metal thickness select will control
both voltage and wire feed speed by
selecting metal thickness.
