The valve pin is a crucial member of the system. Its function is
to open the gas flow check valve that is permanently assembled
within the torch head. If the pin is not correctly placed in the
electrode, the valve will not open and the system will not function.
The valve pin also improves electrode cooling by increasing the
velocity of air over the inner surface of the electrode.
Make sure power switch on console is in the "off" position and primary input power
is deenergized.
the torch head contains a gas flow check valve and a nozzle back pressure tap that
act in conjunction with circuitry within the power source. this system prevents the
torch from being energized with high voltage if the torch switch is accidentally closed
when the shield is removed. alWaYs rEplacE torch WIth thE propEr torch
