How to Set Up for Tig Welding
Welding is a great process for both creating and repairing metal objects. TIG welding in particular is very clean and precise, making it the best choice for exacting work. As with any welding process, proper setup will produce the best results. Does this Spark an idea?
Things You'll Need
- TIG welding machine including inert gas
- Filler material rods
- Welding helmet
- Welding gloves
- Heavy protective clothing of cotton, wool or leather---no synthetics
- Industrial safety glasses
- Fire extinguisher
- Welding table
- Stool
- Compatible electrical outlet

1
Set up the TIG welder in a well-lighted, uncluttered work space that is free of flammable materials. If the work is small, a metal welding table should be used. A table provides a platform on which the work can be set up and clamped in place. The ground may also be attached to the table, making it easier to position the work. Have an ABC fire extinguisher nearby.

Inspect the tungsten tip to be sure that it is clean and is ground to a dull point---regrind if necessary. Connect the torch to the machine (connect the gas line if it's separate). Connect the remote foot pedal (controls the power). Check the polarity switch---normally it will be set to DC for steels and AC for aluminum.

Tips & Warnings
TIG welding involves a balance between distance from the weld, power applied to the weld and speed at which the weld puddle moves along the work. Proper instruction will go a long way to getting these right. Proper instruction also enhances safety.
Before you do your first job, practice on scrap metal. You will learn much in just a few practice sessions.
TIG welding involves handling molten metal and controlling high-amperage electric current. These things are dangerous. Always wear protective clothing and comply with safety procedures (refer to the owner's manual).
