REAR CONTROLS:

GAS PURGE PUSHBUTTON

The gas solenoid valve will energize but neither the power source output nor the drive motor will be turned on. The Gas Purge switch is useful for setting the proper flow rate of shielding gas. Flow meters should always be adjusted while the shielding gas is flowing.

POWER-UP SEQUENCE

For feeders with analog voltmeters, the thermal LED will briefly light during power-up.

If the gun trigger is activated during power up, the feeder will not operate until the gun trigger is released.
