Abstract: A connector for connecting a welding torch, where the connector body and the house are made of insulating material and designed as a unit in one piece connected by a rear wall. The connector includes an insert made of electrically conductive material carrying a threaded surface made of electrically conductive material and a contact surface. The insert can be fitted in a nest formed by a side surface of the connector body part and a surface of the house part opposite to the side surface. An opening on the sidewall of the house part provides access to the side surface of the insert for connecting the side surface to a current, and the insert is secured rotationally in the nest.

Abstract: The invention relates to a connector (10) for connecting welding torch where the connector comprises a connector body (12) made of electrically insulating material, a cylindrical current transferring body (30) fitted on the cylindrical front part (13) of the connector body (12), made of electrically conductive material, where the current transferring body (30) has a threaded surface (32) and a side contact surface (35) besides the threaded surface (32) on its side surface, a threaded bore (37) on the side contact surface (35) for fixing current cable with screwed joint and a frontal contact surface (33), further an attachment bracket (60), made of electrically insulating plastic, the attachment bracket (60) has a sleeve part (62), which encircles space apart the threaded surface (32) and the sleeve part (62) has a flange (64) protruding from its front part for fixing,—the flange (64) is provided with one or more holes (65) in it.

Abstract: The wire feeder apparatus according to the invention has a carrying body (12), tubular guide elements fixed in the openings on the two opposite sides of the body determining a straight-line path for welding wire, further, two spatially separated feed rolls (33, 34) with parallel axles and provided with grooves on their curved surface fitting to the path of wire. The feed rolls (33, 34) are pivotally fixed on the mounting plate of the carrying body and they are individually connected to a gear-wheel via interlocking connection. A pressure arm (14) is fixed to the carrying body (12) by a turning joint, which pressure arm carries two pinch rollers (43, 44) having parallel axles with the feed rolls.
