Set up
installation
for TIG
Welding
Switch the ON/OFF Switch (located on the rear panel) to OFF.
(1) Connect the earth lead to “+”, tighten clockwise; Connect the earth clamp to the work piece.
Contact with the work piece must be firm contact with clean, bare metal, with no corrosion,
paint or scale at the contact point.
(2) Connect the TIG torch cable to “-”, tighten clockwise.
(3) Connect TIG torch gas connection to the TIG gas outlet , ensuring all connections are tight.
(4) Connect TIG torch remote plug to remote socket
，
ensuring all connections are tight.
(5) If using a water cooled torch, Connect the water cooling lines from the TIG torch to the front of
the water cooler, ensuring the red and blue return and supply lines match the connectors.
(6) If using a water cooled torch, connect the water cooler interface cable from the rear of the
power source to the rear of the water cooler.
(7) Connect the gas regulator to the Gas Cylinder and connect the gas line to the Gas Regulator.
(8) Connect the gas line to the machine inlet gas connector via the quick push lock connector
located on the rear panel. Check for Leaks!
(9) Open gas cylinder valve and adjust regulator, flow should be between 5-10 l/min depending on
application. Re-check regulator flow pressure with torch valve open as static gas flow setting
may drop once gas is flowing.
(10) Each machine is equipped with a power cable should be based on the input voltage welding
power cable connected to the appropriate position, not to pick the wrong voltage;
NOTE:
-
Secure the gas cylinder in an upright position by chaining them to a stationary support to prevent
falling or tipping.

Operation
for TIG
Welding
(1) According to the above method to install is correct, turn the power switch to the “ON” position,
the power L.E.D. light should illuminate, the fan comes on, the device work properly.
(2) Set the welding mode to ‘Lift TIG’ or ‘HF TIG’.
(3) If a water cooled torch and water cooler is used, check the water cooler has sufficient coolant
level and all connections are firmly secured, then switch on the water cooler power switch on the
rear of the water cooler. Set the water/air setting button (14) to ‘water (16)’. The water cooler
should now start operating. If using an air cooled torch, set the button (14) to ‘air’ setting (15).
(4) Set the welding parameters as required using the parameters control knob (following the
instructions in the previous section).
(5) The tungsten must be ground to a blunt point in order to achieve optimum welding results. It is
critical to grind the tungsten electrode in the direction the grinding wheel is turning.
(6) Install the tungsten with approximately 3mm to 7mm sticking out from the gas cup, ensuring you
have correct sized collet.
(7) Tighten the back cap.
(8) Commence welding. If necessary, readjust the parameters control knob to obtain the welding
condition re-quired.
(9) After completion of welding the Power Source should be left turned ON for 2 to 3 minutes. This
allows the fan to run and cool the internal components.
(10) Switch the ON/OFF Switch (located on the rear panel) to the OFF.
