How to Set Up TIG Welders
A TIG (Tungsten Inert Gas) welder makes almost any welding project possible because of its vast versatility of functions and abilities. TIG welders use a non-consumable tungsten electrode to weld virtually any metal. TIG welders are used mainly for commercial jobs. Some home workshops are lucky enough to have a TIG welder as a special toy. Setting up the TIG welder is a simple and universal process, regardless of the brand of welder.

1
Connect the torch by plugging the torch into the front of the machine. If you are using an air-cooled torch, you will need to use the adapter that came with the machine. Connect the gas hose and the regulator after your torch is plugged in.
-
2
Connect the fingertip control or the foot petal into the front of the machine.

3
Plug the work clamp or ground clamp into the machine. Connect the clamp to the work table or other surface that is grounded.
-
4
Choose polarity depending on the material you are welding. The settings are located on the front panel. Aluminum welding requires the amperage to be set on AC. Steel and steel alloy require the amperage to be set on DCEN and stick welding requires a setting of DCEP.

5
Prepare the tungsten by grinding it to a point with a grinding wheel.
-
6
Put the torch together. Assemble the torch by rotating the black cap. Remove the 3/32-inch piece of tungsten from the torch. Detach the nozzle and copper collets from the torch. Return the collet and collet body to the torch and secure. Reattach the nozzle on the torch.
-
7
Insert the tungsten into the collet with 1/8 to 1/4 inch extending beyond the collet. Rotate the black cap to tighten.
-
8
Check the voltage of your power supply. The power supply should match with the TIG welder machine rating (found on the label of the welder). Plug your machine into the power supply.

Tips & Warnings
To create a point on the tungsten, a bench grinder works the best. Use a diamond or fine grit stone.
Always wear protective clothing and face gear when welding.
