Gas Valve Removal Tool
Gas valve removal is often required to replace the standard valve stem with
a modified valve stem (P/N 431-1080) when placing an older model gun on
a newer model wire feeder. This is performed by using P/N 931-0105 Gas
Valve Removal Tool. This multifunctional tool has been slotted on one side
to encompass and conform to the gas valve stem and seat into the slotted
gas valve body as seen in Figures 1 and 2. Removal of the gas valve can be
accomplished by turning the gas valve tool counter clockwise. Reinstall by
turning clockwise. The tool doubles as a bottle opener.
