3.14 Setup for TIG (GTAW) Welding
A. Select Lift TIG or HF TIG mode with the process selection control (refer to Section 3.08.7 for further information).
B. Connect the TIG Torch to the negative welding terminal (-). Welding current flows from the power source via
heavy duty bayonet type terminals. It is essential, however, that the male plug is inserted and turned securely
to achieve a sound electrical connection.
C. Connect the work lead to the positive welding terminal (+). Welding current flows from the Power Source via
heavy duty bayonet type terminals. It is essential, however, that the male plug is inserted and turned securely
to achieve a sound electrical connection.
CAUTION
Loose welding terminal connections can cause overheating and result in the male plug being fused in
the bayonet terminal.
D. 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 or HF TIG Mode.
Note: See Appendix A3 for TIG torch contents and trigger switch options.
