Welding torch with a drive unit and a wire buffer store

Abstract

The invention relates to a welding torch with a torch body and a drive unit, for supplying a welding wire, in particular, for differing wire feed speeds, or a forward / backward wire feed and a tube assembly, connected to the torch body at an angle to a mid axis of the welding torch, whereby a wire core, for the welding wire, or the welding wire itself follows a curved course to form a wire buffer store and the amount of the welding wire contained in the wire buffer store can be adjusted by changing the curved course. According to the invention, a welding torch may be produced which is as simple and compact in construction as possible with an improved dynamic property for the wire feed, whereby the wire buffer store is arranged directly after the region of the connection of the tube assembly within the torch body and the tube assembly is arranged at an angle of 33 to 90° to the mid axis of the welding torch.

Description

technical field [0001] The invention relates to a welding torch comprising a welding torch body and a drive unit for feeding welding wire, in particular for different wire feeding speeds or forward / backward wire feeding, and at an angle to the central axis of said welding torch to the connection welding The hose set of the torch body, wherein the wire core of the welding wire or the welding wire itself forms a wire buffer reservoir along a curved path, and the amount of welding wire in the wire buffer reservoir can be adjusted by changing the curved path adjust. Background technique [0002] The welding wire is conveyed by means of a drive unit which is generally arranged in the torch housing, in particular with different wire feed speeds or different feed directions. However, the drive unit can also be arranged in a separate module outside the torch housing or in a separate part of the torch housing. [0003] In recent welding techniques, the wire is no longer just fed at...

AI Technical Summary

Problems solved by technology

A problem with current wire feed systems is that the wire feed response behavior is rather slow due to varying wire speeds and / or wire feed directions, preventing optimal welding results from being achieved

[0009] The disadvantage in this case is that this construction does not allow for a wire buffer reservoir, so the wire has to be pushed back over the entire hose set when the direction of wire feed is changed
