Abstract: A welding torch includes a torch housing and, preferably, a tube bend fastenable thereto. A drive unit for feeding a welding wire is arranged in the torch housing and is formed by at least a drive roller and a pressure roller, as well as a drive motor. Part of the torch housing is designed as a component of the drive unit. A rotor, in particular a motor shaft, of the drive motor is fastened to the torch housing via a bearing or bearings to stabilize and position the rotor. A welding wire feed drive motor includes bearings, a rotor, in particular a motor shaft and a rotor winding or rotor magnets, and a stator pack, in particular stator winding or stator magnets. At least a part of the motor shaft, in particular the retention zone of a drive roller, is electrically insulated from the stator housing or base body.

Abstract: In a welding torch including a torch housing (28) and, preferably, a tube bend (29) capable of being fastened thereto, wherein a drive unit (30) for feeding a welding wire (13) is arranged in the torch housing (29) and the drive unit (30) is formed by at least one pair of rollers, in particular a drive roller (31) and a pressure roller (32), as well as a drive motor, a part of the torch housing (28) is designed as a component of the drive unit (30). A rotor (45), in particular a motor shaft (46), of the drive motor (33) is fastened to the torch housing (28) via a bearing, in particular via bearings (43, 44), to stabilize and position the rotor (45).

Abstract: The invention relates to a device for protecting the housing (26) of a welding component while changing the position thereof, wherein a drag protection (27) in the form of a plate (28) is provided for fastening and for protecting the housing (26), which plate (28) is provided on an outer side (29) with elevations (30) for reducing a bearing surface and a friction resistance.
