A flexible wire guide conduit includes a plurality of modules that can be chained together and can pivot and rotate relative to each other. Each module is formed of two halves that are generally mirrors of each other across a mating plane between the halves. Each module includes an upper flange and a lower flange defining a receiving cavity. Each module includes a tongue member sized to correspond to the cavity that is received in the receiving cavity. The flanges include protrusions extending into the cavity to define a pivotable axis. The tongue includes a bore that receives the protrusions of the adjacent module in the chain. The flanges each include a peg extending into the cavity. The pegs are received in slots formed in the tongue and will slide within the slots during pivoting. The pegs and slots define the degree of pivoting permitted between adjacent modules.

A plurality of wire guide modules are interconnected and pivotally attached to each other. The wire guide modules are pivotable between straight configuration and a curved configuration. Each wire guide module defines a channel (22) extending longitudinally therethrough with bearings (24, 26, 28) on opposite lateral sides of the channel. The wire guide modules are defined by first (10a) and second (10b) halves that are joined together to define the channel and retain the bearings. Each wire guide module defines a slot portion (40a) at a first end and tongue portion (42a) at the second end. The tongue portion is sized to be received within the slot portion. The tongue portion defines a pivot hole and the slot portion defines pivot pins received in the pivot hole to define the pivot axis therebetween.

A welding rod supply system for a welding unit, especially for a welding robot, includes a welding rod supply unit (12) to be coupled with a welding torch (14). The welding rod supply unit (12) includes a rod guide duct (18) formed therein as well as at least two welding rod-receiving cables (22, 24). The at least two welding rod-receiving cables (22, 24) adjoin the welding rod supply unit (12) and are each to be coupled with a welding rod feed unit and are each associated with a rod guide duct (26, 28) formed therein.

A wire feeding system, in particular for feeding a so called cold wire or wire with no tension nor signal running on its surface, in which the pulling or holding of the wire by the front wire feeder puts the rear pushing slave booster respectively into a pre-set active full motor torque or into a pre-set stand-by minimum motor torque, as needed. Alternatively, a wire feed system for feeding a so called cold wire or wire with no tension nor signal running on its surface, in which the rear pushing slave booster is remotely controlled by an optic sensor positioned nearby the torch and sensing the light of the torch welding or spraying arc.

A welding system and a method of control. The welding system may include a weld gun that may have an induction coil and a guide sleeve. The induction coil may heat a welding electrode in the weld gun. The guide sleeve may inhibit the welding electrode from engaging the induction coil.

A welding torch includes a contact tip and a wire electrode guide extending distal of the contact tip. The wire electrode guide includes a metallic outer sheath and a plurality of ring-shaped electrical insulators stacked axially within the metallic outer sheath so as to form a central wire electrode receiving bore through the plurality of ring-shaped electrical insulators.

Present embodiments include a system that includes a welding tool configured to receive a welding wire from a wire feeder, to receive welding power from a power source, and to supply the welding wire to a workpiece during a welding process. The system also includes a mechanical oscillation system configured to mechanically oscillate a structural component toward and away from the workpiece. The structural component is external to the wire feeder and the power source. The system further comprises control circuitry configured to control the welding power based on feedback relating to the welding process.

An arc welding system includes a welding torch, an electrode, and a power supply having a switching-type power converter connected to the torch. A parallel state-based controller is connected to the power converter and provides a waveform control signal thereto for controlling its operations. The controller generates a motion control signal for controlling movements of the electrode and/or the torch. A sensor senses welding voltage or welding current. A memory stores a welding state table comprising sequential control states, and stores a motion control system state table comprising further sequential control states. The welding waveform is defined in the welding state table. The controller controls the operations of the power converter through the waveform control signal according to the welding state table, simultaneously adjusting the motion control signal according to the motion control system state table. The controller transitions between control states according to the signal received from the sensor.
