3.4 Set-up For LIFT TIG (GTAW) Welding

Before any welding is to begin, be sure to wear all
appropriate and recommended safety equipment.
WARNING
NOTE
The following set up is known as Straight Polarity or DC electrode positive. This is
commonly used for DC LIFT TIG welding on most materials such as steel and stainless
steel.
1. Switch the ON/OFF Switch (located on the rear panel) to OFF.
2. Connect the work lead cable to the positive output terminal, and the LIFT TIG Torch
cable to the negative output terminal.
3. Connect the gas line/hose to the proper shielding gas source.
4. Slowly open the Argon Cylinder Valve to the fully open position.
5. Connect the work lead clamp to your work piece.
6. The tungsten must be ground to a blunt point (similar to a pencil) in order to achieve
optimum welding results. See illustration. It is critical to grind the tungsten electrode
in the direction the grinding wheel is turning. Grind at a 30 degree angle and never
to a sharp point.
7. Install the tungsten with approximately 1.6mm to 3.2mm sticking out from the
gas cup, ensuring you have correct sized collet.
8. Tighten the back cap.
9. Turn the switch to the "ON" position. The power L.E.D. light should illuminate.
10. Set the welding process to LIFT TIG.
11. Set the Weld Current Control Knob to the desired amperage.
12. You are now ready to begin LIFT TIG Welding.

necessary. It is important to note that any extension of mains cables or torch cables will
possibly affect the cutting performance of this cutting equipment, due to the fact that the
resistance of the cable will reduce voltage input, which is determined by the length of the
cable. The supplied length of main cables and torch cables is recommended.
