Embodiment Construction

[0047] figure 1 A schematic diagram of a hose set 1 according to the invention is shown, which is used, for example, in an arc welding torch or an arc cutting torch. In the exemplary embodiment selected here, the hose set 1 comprises a plurality of individual hoses in an outer hose 2 and guides them from a not shown base part of the welding machine to a likewise not shown handpiece Or lead from the base part of an automated welding machine to an actuator.

[0048] The hose set 1 has a coolant supply hose 3 within which coolant is conveyed from the base part to the handpiece or the actuator. Furthermore, a process gas hose 4 is provided, inside which process gas for generating a protective gas atmosphere flows. Furthermore, a wire feed hose 5 is provided, which feeds the welding wire 6 within a wire feed screw 7 arranged in the wire feed hose 5 . Furthermore, a control line 8 is provided, by means of which control signals are transmitted from the handpiece or actuator to the...

Abstract

The invention relates to a hose assembly (1) of an arc welding or cutting torch, having a plurality of current-conducting leads (25, 44), wherein the leads (25, 44) comprise an aluminum wire, the current-conducting leads (25, 44) are accommodated in a channel, and wherein the hose assembly (1) has a channel (5, 22) for guiding a welding wire (6, 21).

Description

technical field [0001] The invention relates to a hose set for an arc welding torch or an arc cutting torch having a plurality of current-carrying lines, wherein the lines have an aluminum wire, the current-carrying lines being received in a channel, wherein , the hose set has a channel for guiding the welding wire. Background technique [0002] Arc welding torches and arc cutting torches have been known for a long time in the prior art. These welding torches and cutting torches can be constructed for manual or automatic welding. Arc welding torches or arc cutting torches for manual applications typically have a base and a handpiece that are connected to each other by a hose set. In manual arc welding torches and arc cutting torches it is necessary that the handpiece be as freely movable as possible. Therefore, the material must have good mechanical resistance in particular under bending and torsional loading. [0003] Arc welding torches and arc cutting torches for auto...
