REAR CONTROLS:

OPERATION

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.
