4-3. Volt-Ampere Curves
The volt-ampere curves show the
minimum and maximum voltage
and amperage output capabilities of
the welding power source. Curves
of other settings fall between the
curves shown.
.Ranges 4, 5, and 6 apply to 230
VAC only.

4-4. MIG Welding Gun Duty Cycle And Overheating
CAUTION
WELDING LONGER THAN RATED DUTY CYCLE can damage gun and void warranty.
Do not weld at rated load longer than shown below.
Using gasless flux cored wire reduces gun duty cycle.
warn7.1 8/93
Duty Cycle is percentage of 10
minutes that gun can weld at
rated load without overheating.
