3.22 Setup For LIFT TIG (GTAW) Welding
A. Select LIFT TIG mode with the process selection control (refer to Section 3.10.13 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.
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 Mode.
NOTE
A Thermal Arc 26V TIG torch with an 8 pin plug must be used to turn the weld current ON/OFF via the TIG
torch trigger switch to TIG weld OR a Thermal Arc Foot Control with an 8 pin plug must be used to turn
the weld current ON/OFF as well as providing remote control of the weld current.
