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

Minutes

Duty Cycle is percentage of 10 minutes that gun can weld at rated load without overheating.
