Abstract: The disclosure relates to a welding torch with a flexible welding torch head. The head is in the form of a ball and socket with a fluid passage and is biased in position by disc springs which also have fluid passages.

Abstract: A swivel connector is characterized by an elongated shaft member having an axis extending therethrough and a collar fixed thereon. A moveable sleeve is mounted on the shaft member and is axially moveable from a first to a second axial position relative to the shaft. In the first axial position, the sleeve is rotatable relative to the shaft member. In the second axial position, the sleeve is engaged with the fixed collar and non-rotatable relative to the shaft member.

Abstract: An adjustable welding head oscillator in which rotary motion is transformed into sinusoidal reciprocatory motion and transferred to a welding head. A cam follower is adapted for receiving rotary motion from an eccentric arm and translating the rotary motion into sinusoidal reciprocatory motion. The cam follower is mounted on a swing bar having another point along its length connected to the cam follower which is reciprocated with the same amplitude as the cam follower. The welding head is attached to the reciprocating swing bar at selected points along the length of the swing bar. The amplitude of oscillation of the welding head is adjusted by varying the location of the welding head with respect to the swing bar.

Abstract: The controller automatically and remotely controls the stopping and running of an internal combustion engine coupled to a DC generator that supplies DC power to the welding cables of an arc welding machine. The engine has a starter, an ignition, and an intake manifold. A vacuum-actuated switching means is coupled to the intake manifold and is responsive to the vacuum produced therein. A switching circuit is coupled to and is controlled by the vacuum-actuated switching means. A starter and an ignition are coupled to the switching circuit. A timer having a predetermined timing interval is coupled to the switching circuit, to the welding circuit, and to the ignition.
