Electrode Face:
Use a flat electrode face for most applications. Use a “domed” face if surface oxides are a
problem. If either of the workpieces is a wire, the diameter of the electrode face should be
equal to or greater than the diameter of the wire. If both workpieces are flat, the face
should be at least one-half the diameter of the electrodes.
Pencil point
electrodes reduce
the overall quality of the welding process, and are not recommended.
Welding Transformer Parameters
Primary Tap and Secondary Tap: Set the Primary Tap to the #1, the
lowest
tap on Unitek Peco Transformers
and, if appropriate, select the
lowest
Secondary Tap.
