Set-Up For Lift Tig (Gtaw) Welding; Setup For Stick (Mma) Welding - Vector Welding AC/DC WIG 200D Operating Instructions Manual

AC/DC WIG SERIES EQUIPMENT
Operation
AC Balance Control
Controls arc cleaning action. Adjusting the % EN of the AC wave controls the width of the
etching zone surrounding the weld.
Note:
Set the AC Balance control for adequate arc cleaning action at the sides and in
front of the weld puddle. AC Balance should be fine tuned according to how heavy or
thick the oxides are.

3.3 Setup For STICK (MMA) Welding

For Alkaline Electrode,connect the electrode holder to the positive welding termimal

Electrode,please connect the electrode holder to the negative welding termimal and
connect the work lead to the positve welding terminal.If in doubt consult the electrode
manufacturer. 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. Select STICK mode with the process selection
control.

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.
