Abstract

Welding current nozzle body in metal, e.g. copper or other current conductive alloy or noble metal has a heat resistant nozzle section (2), on the welding wire exit end of the body.

Description

Nach dem heutigen Stand der Technik gibt es für Schweißgeräte nur Stromdüsen aus Kupferlegierungen.According to the current state of the art Is available for Welders only use contact tips Copper alloys.

Dadurch entsteht das Problem, dass beim permanenten Durchführen des Schweißdrahtes durch die Stromdüse die exakte Drahdurchtführung ausweitet (statt zylindrische Bohrung – elyptische Ausschleifungen) nach gewisser Zeit sich abnutzt und sich Schweißperlen bilden, sowie auch der Schweißdraht sich an der Stromdüse absetzt oder verschweißt. Somit ist ein präzises Schweißen und präzise Lichtbogenführung nicht mehr gewährleistet.This creates the problem that with permanent execution of the welding wire the contact tip extends the exact wire feedthrough (instead of cylindrical drilling - Egyptian grindings) after a while it wears out and beads of sweat form, as well the welding wire at the contact tip settles or welded. It is therefore a precise one welding and precise Arc guide no longer guaranteed.

Dabei entsteht ein Drahtführungsstau.This creates a wire guide jam.

Durch die neue angebrachte Keramik-Düse sind die oben angeführten Probleme beseitigt, da sie sich weder mit irgendeiner Schweißdrahtlegierung verbinden kann und eine wesentlich höhere Abriebfestigkeit hat.Thanks to the new ceramic nozzle the above Problems solved as they do not bond with any welding wire alloy can and a much higher Has abrasion resistance.

Durch die wesentlich höhere Standzeit der neu entwickelten Stromdüse hat man eine enorme Kosteneinsparung.Due to the much longer service life the newly developed contact tip you have enormous cost savings.

Dazu hat man den Vorteil, dass kein Düsenschutz-Spray verwendet werden muss, um die Stromdüse vor Verklebungen oder Verschweißungen zu schützen.The advantage of this is that none Nozzle protection spray must be used to protect the contact tip from sticking or welding protect.

Zusätzlich entfallen die Kosten für teuere Schutz-Sprays oder Wachse.In addition, there are no costs for expensive protective sprays or waxes.
