Problems solved by technology

[0004] The disadvantage of this type of fastening system is that, for fastening, additional devices or manufacturing steps are required on the gas nozzle, such as threads, multiple slots or two protrusions
A disadvantage especially in DE 203 80292 U1 is that attention must be paid to the position of the gas nozzle for fixing

Abstract

The invention relates to a system for attaching a gas nozzle (33) to a gas nozzle holder (30) disposed on a welding torch (10), said holder being configured for the removable attachment of the gas nozzle (33). One part of the gas nozzle holder (30) is configured eccentrically. In order to create such an attachment, the eccentric part of the gas nozzle holder (30) is configured for receiving a ring fixing element (35) and that another part of the gas nozzle holder (30) together with at least one part of the nozzle fitting (31) of the welding torch (10) forms a guide for the gas nozzle (33) and the gas nozzle (33) can be attached by way of rotary movement. The fixing element (35) is formed by an open ring. Each end of the ring rises in a radial direction relative to the outline of the circular ring part.

Description

technical field [0001] The invention relates to a system for fastening a gas nozzle to a gas nozzle receptacle arranged on a welding torch, which is designed for detachable fastening of the gas nozzle. [0002] The invention also relates to a gas nozzle for a welding torch which is tubular in design and surrounds at least one nozzle holder and is fastened to the gas nozzle receptacle. Background technique [0003] Fastening systems for gas nozzles of welding torches are already known, in which the gas nozzles are simply plugged directly onto the base body. For this purpose, slots are usually provided in the gas nozzle, through which the tension holds the gas nozzle. Furthermore, torches are also known in which a threaded connection for receiving a gas nozzle is provided on the base body. A fastening system is also known in which the gas nozzle is fastened by means of a short rotational movement, as is known from DE 203 80 292 U1. [0004] A disadvantage of such fastening ...
