Typical MIG Process 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.

NOTE

3.5 x 125 A = 437 ipm

2 x 125 A = 250 ipm

1.6 x 125 A = 200 ipm

30 − 90 A

40 − 145 A

50 − 180 A

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

Ref. 804 620-A

Voltage controls height
and width of weld bead.

Wire speed (amperage) controls weld
penetration (wire speed = burn-off rate)
