Zusammenfassung:The invention relates to a welding torch (10) having a torch body (46) in which at least one device (32) for feeding a welding wire (13) and a contact tube (30) having a bore (33) and a guide bore (34), running concentrically thereto, for guiding the welding wire (13) in the direction of a workpiece (16) are arranged, wherein the welding wire (13) can be supplied with electrical energy via the contact tube (30), wherein one end of the feed device (32) is arranged in the guide bore (34) of the contact tube (30) and is provided with an electrically conductive end piece (36) having a bore (40) for the welding wire (13). To provide such a welding torch (10) in which the durability or the service life of the wearing parts, in particular of the contact tube (30), is prolonged, provision is made for the end piece (36) of the feed device (32) to be movably arranged in the guide bore (34) of the contact tube (30).
