Becoming a good welder will take many hours of practice.

Step 1: Holding and Moving the Torch

Hold the torch so the tungsten is about 1/8" above the workpiece.

The angle that the torch intersects the workpiece is known as the work angle. In general, the torch should bisect the angle of the two workpieces.

Step 2: Using the Torch

There are three actions the user must do at the same time.

  1. Press the pedal with your foot.
    • Press the pedal further for more heat.
  2. Hold the torch in one hand 1/4" to 1/2" away from the material.
    • Hold the torch still to form a small puddle.
  3. Hold the filler rod with the other hand.
    • Dip the filler rod into the molten puddle.
    • Do not heat the filler rod.

After dipping the filler rod, move the torch slightly to the left, and repeat steps 2 & 3 (if welding from right to left).

Each puddle should overlap the previous and form a continuous bead of weld.
