6.02 Setup for TIG (GTAW) Welding
A. Connect the TIG Torch to the negative welding terminal (-). Welding current flows from the power source
via Dinse terminals. It is essential, however, that the male plug is inserted and turned securely to achieve
a sound electrical connection.
B. Connect the TIG torch trigger switch via the 8 pin socket located on the front of the power source as shown
below. The TIG torch will require a trigger switch to operate in Lift TIG Mode.
NOTE!
If the TIG torch has a remote TIG torch current control fitted then it will require to be connected to the 8 pin socket.
(Refer to section 4.02.9 Remote Control Socket for further information).
C. Switch the Power Source On/Off switch located on the rear of the Power Source to the On position and
ensure the Power indicator on the Front Panel is illuminated.
D. Select Lift TIG mode with the process selection control (refer to Section 4.02.13 for further
information).
E. Connect the work lead to the positive welding terminal (+). Welding current flows from the Power Source
via Dinse terminals. It is essential, however, that the male plug is inserted and turned securely to achieve
a sound electrical connection.
F. Fit the welding grade shielding gas regulator/flowmeter to the shielding gas cylinder (refer to Section 6.01)
then connect the shielding gas hose from the TIG torch to the regulator/flowmeter outlet. Note that the TIG
torch shielding gas hose is connected directly to the regulator/flowmeter. Before turning on shielding gas
check that all fittings are tight and the gas valve on the TIG torch is turned off. The power source is not
fitted with a shielding gas solenoid to control the gas flow in TIG mode therefore the TIG torch will require
a gas valve.( Refer to Section 2.11 for optional TIG Torches). Before commencing to TIG weld open TIG
torch gas valve to allow sufficient shielding gas flow when welding. Refer to Section 6.03 for recommended
Shielding Gas flow rates and other TIG Welding information.
WARNING
Before connecting the work clamp to the work make sure the mains power supply is switched off.
!
WARNING
Secure the welding grade shielding gas cylinder in an upright position by chaining it to a
suitable stationary support to prevent falling or tipping.
!
CAUTION
Loose welding terminal connections can cause overheating and result in the male plug being fused in the terminal.
Remove any packaging material prior to use. Do not block the air vents at the front or rear of the Welding Power Source.
