Form of the electrode tip
Tungsten electrodes must always be welded in
longitudinal direction, as grinding scores running
transversely result in an unsteady electric arc.
The top of the electrode for DC welding must be and
remain pointed like a pencil.
The tip angle here depends on the welding current
strength.
