Abstract
In the case an arc welding torch device, having a consumable electrode. The electrode in the arc welding torch device is guided in an exchangeable wire core, the wire core being arranged at least in the region of the rear end of the arc welding torch device in a guide element surrounding the wire core and designed as an exchangeable wear part, and the guide element of the wire core being provided for the joint exchange of the wire core due to wear. It is proposed that a predetermined end position in the arc welding torch device is provided for the guide element with respect to its insertion direction into the arc welding torch device, and when the end position is attained by the guide element, a position signaling means is perceptible outside the arc welding torch device.
Claims24
An arc welding torch comprising:
- a jacket tube having an end cap arranged at a rear end of the arc welding torch;
- a guide element movable along a longitudinal axis of the jacket tube, the guide element having an end region, the end region having an end portion that extends through the end cap and is visible outside the arc welding torch when the guide element is correctly positioned inside the arc welding torch;
- and
- an exchangeable wire core arranged in the guide element,
- wherein a consumable electrode is guided in the exchangeable wire core from the rear end to a welding process end of the arc welding torch, and
- wherein the consumable electrode is consumed at the welding processing end during an arc welding process.
An exchangeable assembly for an arc welding torch comprising:
- a guide element including a first section having an end portion and a first outer diameter, and a second section having a second outer diameter, the second outer diameter being larger than the first outer diameter, and a conical section adjoining the first section and the second section;
- a wire core arranged inside the guide element;
- and
- an end cap disposed on a rear end of the arc welding torch, the end cap including a through hole,
- wherein the end portion protrudes from the through hole of the end cap.
An arc welding torch comprising:
- an outer end cap arranged at a welding process end of the arc welding torch;
- a wire feeding means disposed adjacent to the end cap;
- a guide element movable along a longitudinal axis of the arc welding torch;
- an exchangeable wire core arranged in the guide element;
- and
- a kink protection means for a consumable electrode, the kink protection means disposed between the outer end cap and the wire feeding means and facilitating guiding of the consumable electrode,
- wherein the consumable electrode is guided in the exchangeable wire core from a rear end to the welding process end of the arc welding torch, and
- wherein the consumable electrode is consumed at the welding processing end during an arc welding process.
