12-2. 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.

1 Convert Material Thickness to
Amperage (A)
(.001 in = 1 ampere)
.125 = 125 A
.
Material thickness determines weld
parameters.
2 Select Wire Size
Amperage Range
Wire Size
.030 in 40 − 145 A
.035 in 50 − 180 A
.045 in 75 − 250 A
3 Select Wire Speed (Amperage)
125 A based on 1/8 in (3 mm) material thickness.
(ipm = inch per minute)
Wire Wire Speed
Suggested
Size
.030 in 2 in per amp 2 x 125 A = 250 ipm
.035 in 1.6 in per amp 1.6 x 125 A = 200 ipm
.045 in 1 in per amp 1 x 125 A = 125 ipm
.
Wire speed (amperage) controls weld pene-
tration (wire speed = burn-off rate).
4 Select Voltage
Low Voltage: wire stubs into work
High Voltage: arc is unstable (spatter)
Set voltage midway between high/low voltage.
.
Voltage controls height and width of weld
bead.
