2-2 Duty Cycle and Overheating
Duty Cycle is percentage of 10 minutes that unit can weld at rated load without overheating.
Using mixed gases other than CO
2
reduces duty cycle ratings 10-50% depending on gas mixture and welding parameters.
Please reference Section 2 — Specifications on page 8 for duty cycle ratings by amperage.
