6-2. 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.

3.5 x 125 A = 437 ipm
2 x 125 A = 250 ipm
1.6 x 125 A = 200 ipm

controls weld penetration
(wire speed = burn-off rate)
Voltage controls height and width
of weld bead.
