Becoming a good welder will take many hours of practice.

Step 1: Holding and Positioning the Torch

Hold the torch so the wire is about 1/4" 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.

The angle of the torch in relation to its movement is known as the torch angle.

  • The torch can be pulled or pushed, depending on many factors including personal preference.

Step 2: Moving the Torch

The torch can be moved in a straight line (stringer bead), or in small overlapping arcs (weave pattern).

  • A stringer is best for very thin material that cannot take much heat.
  • A weave is better for thicker materials that require more heat.
