1. SETTING UP THE WORK PIECE
a. Welding positions - There are two basic positions, for welding: Flat and Horizontal. Flat
welding is generally easier, faster, and allows for better penetration. If possible, the
work piece should be positioned so that the bead will run on a flat surface.
b. Preparing the Joint- Before welding, the surface of work piece needs to be free of dirt,
rust, scale, oil, or paint, or it will create brittle and porous welds. If the base metal pieces
to be joined are thick or heavy, it may be necessary to bevel the edges with a metal
grinder; the correct bevel should be around 60 degree. See the following illustration:
Based on different welding positions, there are different welding joints. See the following illustration for
more information.
2. GROUND CLAMP CONNECTION
Clear any dirt, rust, scale, oil, or paint on the ground clamp. Make certain you have a good solid
ground connection. A poor connection at the ground clamp will waste power and heat. Make
sure the ground clamp touches the metal.
