Duty Cycle is percentage of 10
minutes that gun can weld at
rated load without overheating.
2-6. Volt-Ampere Curves
.023 To .035 in (0.6 To 0.9 mm) Aluminum Wire
.023 To .035 in (0.6 To 0.9 mm) Hard Or Flux Cored Wires
60% Duty Cycle At 150 Amperes
Using Argon Shielding Gas
6 Minutes Welding 4 Minutes Resting
Volt-ampere curves show minimum
and maximum voltage and amper-
age output capabilities of unit.
Curves of other settings fall be-
tween curves shown.
