GMAW Shielding Gas
The customer must provide a cylinder of shielding
gas, a pressure regulator, a flow control valve, and a
hose from the flow valve to the gas inlet fitting of the
wire drive unit.
Connect a supply hose from the gas cylinder flow
valve outlet to the 5/8-18 female inert gas fitting on the
back panel of the wire drive or, if used, on the inlet of
the Gas Guard regulator. (See Below).
Gas Guard Regulator - The Gas Guard Regulator is
an optional accessory (K659-1) on these models.
Install the 5/8-18 male outlet of the regulator to the
5/8-18 female gas inlet on the back panel of the wire
drive. Secure fitting with flow adjuster key at top.
Attach gas supply to 5/8-18 female inlet of regulator
per instructions above.
