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.
