II. INSTALLATION
2-1 Power Cord
The power cord at the back of the welder is to be connected to a 110/220V AC power supply. Ground the unit
by connecting a 6 mm (10 gauge) wire from the grounding terminal at the back for the machine to the earth.
2-2 Hookups
For TIG
(1) To gas supply: Connect the argon hose to the
copper nozzle on the back panel. The hookups include
gas bottle, air regulator, and gas hose with hose clamp.
(2) Install the argon torch according to the sketch.
Tighten it by turning clockwise. Connect the terminal
of the torch switch cable to the pilot plug on the panel.
(3) Connect the cord of the earth ground clamp to the
“+” connector on the panel, and tighten it by turning
clockwise. Make sure that the earth ground clamp
holds the work piece securely.
For MMA ARC
(1) Connect the fast connector to the terminal of the
electrode holder. Plug securely the fast connector into the
socket on the front panel.
Note: The above method is positive connection, used for
acid welding electrode. However, for alkaline or
stainless steel, negative connection should be used.
For CUT
(1) Connect the compressed gas hose to the IN terminal at
the back of the machine and tighten it with hose clamp.
Make sure the gas pressure is correct.
(2) Connect the cutting torch to the connector on the
panel, and tighten it by turning clockwise. Connect the
switch control cable terminal to the pilot plug on the panel.
(3) Connect the fast connector of the earth ground clamp to anode socket (+) on the panel.
AIR REGULATOR
(1) Install the copper nozzles separately to the “IN” and “OUT” terminals.
