Abstract
In the case of an arc welding torch device with a consumable electrode. The electrode in the arc welding torch device being guided in an exchangeable wire core, a guide element surrounding the wire core and designed as an exchangeable wear part. To reduce the risk of kinking of a welding wire of an arc welding torch device melting in the welding process, a kink protection means protruding from the arc welding torch device is passed through an outer end cap of the arc welding torch and arranged between the outer end cap of the arc welding torch and wire feeding means for the welding wire in which the welding wire is guided is proposed.
Claims12
An arc welding torch device comprising:
- a consumable electrode provided with a direction of movement from a rear end of the arc welding torch device for advancement in the direction of a front end of the arc welding torch device, in a region of which the consumable electrode melts during an arc welding process;
- an outer end cap arranged at the rear end of the arc welding torch device;
- a guide element arranged in a region of the rear end of the arc welding torch device, the guide element having an end region, the end region having a kink protection means comprising an end portion, the kink protection means protruding through the outer end cap in a direction from the front end to the rear end of the arc welding torch device and being arranged between the outer end cap and a wire feed means;
- and
- an exchangeable wire core arranged in the guide element,
- wherein the guide element is provided for joint wear-related replacement of the exchangeable wire core,
- wherein the consumable electrode is guided in the exchangeable wire core from the rear end to the front end of the arc welding torch device, and
- wherein the consumable electrode is consumed at the front end during the arc welding process,
- wherein a maximum outside diameter of the kink protection means protruding from the outer end cap is smaller than a diameter of a through bore of the outer end cap.
