WELDING TORCH WITH A TORCH HOUSING AND DRIVE FOR WELDING ROD TRANSPORT

摘要

The invention relates to a welding torch (10) and/or a rod transport unit, comprising a torch housing (28) and preferably a bent tube (29) which may be fixed thereto. A drive unit (30), for transport of a welding rod (13), is arranged in the burner housing (29), embodied by at least one pair of rollers, in particular, a drive roller (31) and a pinch roller (32) and a drive motor (33). A part of the burner housing (28) is embodied as component of the drive unit (30), whereby a rotor (45), in particular, a motor shaft (46) of the drive motor (33), is fixed to the burner housing (28), for stabilising and positioning the rotor (45), by means of a mounting, in particular, by bearings (43, 44). The invention further relates to a drive motor for welding rod transport, comprising bearings (43, 44), a rotor (45), a motor shaft (46), a rotor winding (49) and a stator laminate, whereby at least a part of the motor shaft (46), in particular, the housing region for a drive roller (31), is electrically insulated from a stator housing (65), or a base body (37) of an external component.
