Protection cap for a tube contact a welding torch, also welding torch with a protective cap.

摘要

Protection cap for a minimum of two tubes (40, 41) of a welding torch (10) each having a hole for driving and establishing contact of a respective welding wire (13) is fed , comprising a housing (33) composed of or coated with a material which is poorly electrically conductive, for accommodating the tubes (40, 41), for which are provided in the housing (33) at least two holes ( 29, 30) for accommodating at least two contact tubes (40, 41) and at least one additional hole (37) for accommodating other elements of the welding torch (10), in particular for accommodating a zone part of a torch body with the contact tubes (40, 41) fixed therein, characterized in that each hole (29, 30) is in communication with a respective hole (31, 32) for exit of the welding wire ( 13) in the housing (33), and in that each hole (31, 32) is arranged such that in mounted the protective cap (27) state coincides with the path of the welding wire (13) in the contact tube (40, 41) so that a welding wire fed (13 ) can go to a spot welding through the holes of each contact tube (40, 41) and each hole (30, 31) of the protective cap (27), and in that an outer surface (34) the housing (33) they are arranged fixing elements (35) formed by at least one bridge (36) through which it can establish a snap connection with a gas nozzle (28) of the welding torch (10) by placing the protective cap (27), which all conductive elements of the welding torch (10) located in the gas nozzle (28), ie at the end of the torch body, are covered by the protective cap (27), holes (38) being arranged in the housing (33) through of which a gas (8) fed by the welding torch (10) can leave the area between the gas nozzle (28) and the protective cap (27).
