Direct current arc welder - with superimposed arc striking supply from HF or pulse generator

The gas or liquid cooled head has a central, non-consumable cathode pin surrounded by an air gap defined by a skirt, forming part of the body, of dielectric material. The ionisation of the air in the gap to strike the arc is produced by a ring electrode on the outer surface of that skirt which elect...

Zusammenfassung:The gas or liquid cooled head has a central, non-consumable cathode pin surrounded by an air gap defined by a skirt, forming part of the body, of dielectric material. The ionisation of the air in the gap to strike the arc is produced by a ring electrode on the outer surface of that skirt which electrode is at the same potential as the workpiece.
