3-4. Duty Cycle And Overheating

60% Duty Cycle At 350 Amperes

6 Minutes Welding

4 Minutes Resting

3-5. AC Auxiliary Power

Duty Cycle is percentage of 10 min- utes that unit can weld at rated load without overheating.

YExceeding duty cycle can damage unit and void warranty.

100% Duty Cycle At 300 Amperes

Continuous Welding

rduty1 5/95 – SB-111 076-A

The ac power curve shows the aux- iliary power in amperes available at the 120 and 240 volt receptacles.
