LIFT TIG / HF TIG (GTAW) Sequence of Operation
CAUTION
Before any welding is to begin, be sure to wear all appropriate and recommended safety equipment.
1. Switch the ON/OFF Switch (located on the rear panel) to OFF.
2. Connect the ground (work) clamp cable to positive output terminal. It is essential that the male plug is
inserted and turned fully clockwise until connector locks in place to achieve reliable electrical connection.
3. Connect the TIG torch as follows:
a) Place the power cable into the negative output terminal. It is essential that the male plug is inserted
and turned fully clockwise until connector locks in place to achieve reliable electrical connection;
b) Place the 8 pin plug into the 8 pin socket. To make connections, align keyway, insert plug, and rotate
threaded collar fully clockwise.
c) Place the TIG torch gas hose to the gas outlet and tighten with a wrench. Caution: DO NOT over tighten.
4. Using a secured Argon cylinder, slowly crack open then close the cylinder valve while standing off to the
side of the valve. This will remove any debris that may be around the valve & regulator seat area.
5. Install the regulator (for details of VICTOR regulator, please refer to 3.08 ) and tighten with a wrench.
6. Connect one end of the supplied gas hose to the outlet of the Argon regulator and tighten with a wrench.
