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.
