3Electrode

A small diameter electrode requires less current than a large one. Fol- low electrode manufacturer’s instructions when setting weld am- perage (see Section 15-2).

5Electrode Holder Position

6Arc Length

Arc length is the distance from the electrode to the workpiece. A short arc with correct amperage will give a sharp, crackling sound.

7 Slag

Use a chipping hammer and wire brush to remove slag. Remove slag and check weld bead before mak- ing another weld pass.
