5.9.3.1 Regrinding the electrode
The electrode shape is decisive for a good welding result. Therefore, it is necessary to grind electrodes
by machine to the correct shape before use. The electrode must be replaced if the electrode tip is exces-
sively worn, tarnished too much, or burned back asymmetrically.
The following guide values apply to the electrodes of the welding torch
