The shape of the electrode for DC welding has to be
and remain as sharp as a pencil. The angle of the point
depends on the welding current. When AC welding, it is
sufcient to sharpen the edge of the electrode slightly.
After a short time, a round to slightly convex form is built.
If the electrode tip is polluted due to dipping into the weld
pool or touching the ller wire, the respective part of the
electrode must be completely ground off. Restore the
original, pointed shape. Grind in longitudinal direction.
