7. Adjust the flow rate of the gas by turning the Flow Adjust. The typical flow rate is
20 CFH (cubic feet per hour). Check the welding wire manufacturer’s
recommended flow rate. (See Figure J.)

Welding Gun Duty Cycle And Overheating:
1. IMPORTANT! Welding longer than the rated duty cycle for this Welding
equipment can damage the Gun and void its warranty.
2. Duty cycle is a percentage of 10 minutes that the unit can weld at its rated load
without overheating. (See Figure L, page 20.)
3. If the unit should overheat, the thermostat opens, output stops, and the cooling
fans continue to run. Wait fifteen minutes for the unit to cool. Reduce amperage
or voltage, or duty cycle, before welding.
4. This Welder, at its 60% duty cycle, can run continuously under load for 6 minutes
out of each 10 minute period. (See Figure L.)
5. NOTE: Higher duty cycles can be used at lower currents. (See Rating Plate
information on Front Panel.)
