How do I set up my TIG welder?

See your Owner's Manual for complete safety, set-up and installation procedures.The following diagram and instructions show a typical TIG welding system and connections.

1. Connect TorchWhen using an air-cooled torch, use the adapter from youraccessory package and plug the torch into the front of yourmachine. Also connect your gas hose and regulator.

2. Connect Remote ControlPlug your foot pedal or fingertip control into the machine.

3. Connect Work ClampPlug your work clamp (sometimes referred to as a groundclamp) into the machine. Clamp the other end to your workpiece or work table.

4. Select PolarityFor aluminum welding, switch your amperage setting on thefront panel to AC. For steel and steel alloy welding, switch youramperage setting to DCEN. (For Stick welding, switch youramperage setting to DCEP.)

5. Prepare TungstenGrind your tungsten to a point. When welding on aluminum,the tungsten will begin to form a ball. If the ball grows to thesame diameter as your tungsten, repoint the tungsten. Grind inthe long direction and make the point roughly 2-1/2 times aslong as the diameter.

Use a 200 grit or finer grinding wheel. Do not use the wheel forother jobs or tungsten can become contaminated causing lowerweld quality.

6. Assemble TorchLoosen the back cap and remove the 3/32" diameter tungstenfrom your torch (it has an orange stripe). Remove the nozzleand copper collet pieces from your torch. Put the collet andcollet body back into the torch and tighten. Put the nozzle backonto the torch.

7. Install TungstenPlace the tungsten into the collet. Leave about 1/8 to 1/4 in.sticking out of the collet (not more than the diameter of thecup). Tighten the back cap.
