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.
