3.3 GTAW (TIG) Welding
Insert the cable plug with the work clamp into the “+”
socket on the front panel of the welding machine, and
tighten it clockwise.
Insert the cables plug of the TIG torch into the “-” socket on
the front panel of the machine and tighten clockwise.
Connect the gas hose to the regulator / flowmeter located
on the shield gas cylinder.
Open the valve on the TIG torch and “scratch” the
electrode on the work piece to start the arc

Connect the TIG torch leads as detailed above. Ensure that a suitable inert gas supply is
connected.

Switch the power switch on the back panel to “ON”

Select the TIG welding mode using the selector switch.

There is voltage output at both output terminals.

After the parameters are set appropriately, open the gas valve of the cylinder, the gas valve on the
torch and adjust the gas regulator to obtain the desired flow rate.

The arc will start when the tungsten electrode touches the work piece and is lifted off after
touching by between 2-4mm

The arc will cease when the electrode (torch) is moved away from the work area
