In the case of plasma solderind, a non-transmitting arc or a transmitting arc can be used.

With the indirect plasma arc, electrically nonconductive materials can also be melted or welded (for example plastic hoses). The great advantage is that this is done under a protective gas atmosphere and so no impurities enter the material (application in the medical and lamp industry). Today systems with capacities up to 2 kW are available as standard.

When soldering with a transmitting arc, the material is preheated but not melted. The connection is effected by the addition of a brazing material. One application is e.g. The repairing of galvanized sheet metal in vehicle construction.
