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.
3. ELECTRODE
The welding electrode is a rod coated with a layer of flux. When welding, electrical current flows
between the electrode (rod) and the grounded metal work piece. The intense heat of the arc
between the rod and the grounded metal melts the electrode and the flux.
4. SELECTING THE PROPER ELECTRODE
There is no golden rule that determines the exact rod or heat setting required for every situation. The
type and thickness of metal and the position of the work piece determine the electrode type and the
amount of heat needed in the welding process. Heavier and thicker metals required more amperage.
It is best to practice your welds on scrap metal which matches the metal you intend to work with to
determine correct heat setting and electrode choice. See the following helpful trouble shooting tips to
determine if you are using a correct electrode.
4.1 When proper rod is used:
4.1a. The bead will lay smoothly over the work without ragged edges
4.1b. The base metal puddle will be as deep as the bead that rises above it
4.1c. The welding operation will make a crackling sound like the sound of eggs frying
4.2 When too small of a rod is used:
4.2a. The bead will be high and irregular
4.2b. The arc will be difficult to maintain
4.3 When the rod is too large:
4.3a. The arc will burn through light metals
