摘要： A method to replace a contact tip in a welding system includes applying a first force toward a neck of a welding torch to remove the contact tip via a quick release mechanism. Additionally, the method includes inserting a new contact tip into the quick release mechanism and applying a second force on the new contact tip toward the neck of the welding torch until the new contact tip is locked in place within the quick release mechanism.

摘要： A consumable electrode gas shield arc welding torch (20) includes a torch body (21), a tip body (22) mounted to a front end of the torch body, a tip holder (23) mounted to a front end of the tip body, a spring (26) provided in the tip body (22) in contact with the front end of the torch body (21), a pressing shaft (27) provided in the tip body (22) in contact with a front end of the spring 26) and a power feed tip (28) pressed by the pressing shaft (27) and the tip holder (23). The tip (28) includes a side surface having a projection contacting with a base end (23a) of the holder (23), with a space (29) defined between an inner surface of the holder (23) and a front end (28a) of the tip (28) when the front end (28a) of the tip (28) is inserted into the holder (23).

摘要： The invention relates to a device and a method for contacting a welding rod (13) in a welding torch (10), comprising at least two contact shells (31) having a contact area (32) for contacting the welding rod (13), and to a contact shell (31) for contacting a welding rod (13). In order to make the contact of the welding rod as constant and permanent as possible during the lifetime of a contacting device, the contact shells (31) have a holding section (48) and are arranged inside a sleeve (37) to define a rotational axis (43), the sleeve (37) being fastened to a nozzle pipe (38) having an integrated pressure mechanism (36), and said pressure mechanism (36) being designed to exert pressure (33) on the contact shells (31). The sleeve (37) comprises a holding device (42) for exerting a counter-force (34) onto the contact shells (31). The welding rod (13) is contacted in the contact area (32) of the contact shells (31) with a contact force (35).

摘要： A contact tip, suitable for electric arc welding using a consumable electrode, has a body which defines a bore through which the electrode is able to pass to enable electric current from a welding power supply to be transferred from the body to the electrode. In part of the length of the bore between an inlet end and an outlet end, the body has at least one region a primary contact region at which the body is adapted to enable primary electrical contact with the electrode. Along a remainder of the length of the bore, the body is adapted such that any secondary contact between the body and the electrode along the remainder part does not substantially short circuit the primary electrical contact in the primary contact region of the bore.

摘要： The present invention relates to a welding torch that includes an electrode (3) that has a longitudinal groove (9) formed therein which guides a welding wire (4) which is fed form a laterally spaced-apart location. The electrode (3) is open and the wire (4) is supported on one side only. In the region of the welding tip, the electrode (3) is elongate and the cross-sectional area is smaller than the area at a position further from the tip. Regions between an outer housing (11) and a main support body (2) define two shielding gas conduits positioned on opposite sides of the body (2), through which gas flows and then combines to form a unitary stream. The body (2) contains cooled regions which are supplied with cooling fluid by a conduit (7) and removed by conduit (8), parts of which are positioned between the shielding gas conduits close to the welding electrode (3).
