3-3. Fuel Consumption

The curve shows typical fuel use under weld or power loads.

SB-137 487-A

3-4. Duty Cycle And Overheating

Duty Cycle is percentage of 10 min-

100% Duty Cycle At 250 Amperesutes that unit can weld at rated load without overheating.

Y Exceeding duty cycle can damage unit and void warranty.
