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 and for purging the lines.. Flow meters should always be adjusted while the shielding gas is flowing.
POWER-UP SEQUENCE
For feeders with analog voltmeters, the thermal LED and the Polarity LED will light breifly during
If the gun trigger is activated during power up, the feed- er will not operate unless the gun trigger is released and

FLOW METER
The flowmeter shows the flow rate of shielding gas and has a valve to adjust the flow. The flow meter is scaled for CO2, Ar, and Ar/CO2 blends. The middle of the ball
indicates the flow rate of shielding gas.
Adjust the flow rate while depressing the GAS PURGE switch by turning the valve at the bottom of the meter. Most weld procedures require
When using a wire feeder with a flow meter, adjust the regula- tor at the shield gas bottle or supply to a flow rate that is higher than the flow rate indi- cated on the feeder flow meter. Note that most regulators are calibrated based upon having low restrictions on the outlet. The valve on the feeder flow meter creates a high restric- tion and may cause errors in the readings at the supply reg- ulator. Set the gas flow rate using the feeder flow meter reading and not the supply regulator reading.
