Convert Material Thickness to

Amperage (A)

(.001 in = 1 ampere)

.125 = 125 A

.

Material thickness determines weld

parameters.

Select Wire Speed (Amperage)

125 A based on 1/8 in (3 mm) material thickness.

(ipm = inch per minute)

.

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.
