Described is a heated gaseous welder system and associated methods of welding plastic with the heated gaseous welder system. The heated gaseous welder system includes a welding tool and a welder control unit. The welder control unit includes a gaseous control system and a heater control system. The gaseous control system is configured to selectively supply a gas to the welding tool and control at least one characteristic of the gas supplied to the welding tool. The heater control system is configured to selectively control power supplied to the welding tool.

One embodiment is a combined welder and fume extractor system having a chassis assembly along with a controller and a user interface which are substantially within the chassis assembly to control operation of the system and allow a user to interact with the system. A filter compartment within the chassis assembly has at least one filter to extract welding fume particles from a stream of air forced through the filter compartment. An extractor compartment within the chassis assembly has at least one fan to force the stream of air through the filter compartment. A welding power source compartment within the chassis assembly has welding power electronics circuitry to generate welding output power for a welding operation. A wire feeder compartment within the chassis assembly has a spool of a welding wire electrode and a wire feeder to feed the welding wire electrode from the spool.

Apparatuses, systems, and/or methods for providing welding systems or portions of welding systems that provide a tip-retention device that is configured to direct gas radially towards a contact tip.

A TIG torch for welding, soldering or coating, wherein an electrode is radially surrounded by an inner gas nozzle as far as the electrode tip. A first gas flow in the direction of a workpiece surface through a gap between the inner lateral surface of the inner gas nozzle and the lateral surface of the electrode. The inner gas nozzle is fastened to a sleeve-shaped inner gas nozzle carrier and is surrounded by an outer gas nozzle fixed to an outer gas nozzle carrier or an outer gas nozzle. A second gas flow in the direction of the workpiece surface between the radially outer lateral surface of the inner gas nozzle and the inner lateral surface of the outer gas nozzle. An electrically insulating element is arranged between the inner gas nozzle carrier, inner gas nozzle and/or electrode and the outer gas nozzle carrier and/or outer gas nozzle.

A plurality of welding torches, which are disposed in a welding device and are made movable in three-dimensional directions, are provided with welding wires that differ in composition and diameter from each other. When welding is performed in the horizontal direction, an arc is generated by at least two of the welding torches to form a bead while the welding wires are being fed. When welding is performed in the vertical direction, the arc is generated by any one welding torch of the two welding torches to form a bead while the welding wire is being fed. Thus, a steel sheet to which an anti-corrosion material has been applied can be welded continuously with high quality and high-efficiency in a horizontal orientation and vertical orientation.

The present disclosure is directed to a system and method for obtaining a desirable shielding gas flow in a welding device. The system includes a user interface configured for a user to input the size of the nozzle, a processor that is configured to calculate a desirable flow rate of shielding gas based at least in part on the input nozzle size, and a flow regulator that is configured to control the flow of the shielding gas in order to obtain the desirable flow rate.

In order to reduce the accumulation of moisture on a welding wire (2, 2, 2) arranged in a welding wire cartridge (1, 1a, 1b) or to remove existing moisture in a simple and reliable manner, it is provided that a flow (D.sub.1) of purging air supplied to the welding wire cartridge (1, 1a, 1b) is adjusted by a flow control unit (14), the purging air is supplied to the flow control unit (14) at a first pressure (p) and is discharged at a purging air discharge (24) of the welding wire cartridge (1, 1a, 1b) at a third pressure (p.sub.at), and at a purging air feed (15) of the welding wire cartridge (1, 1a, 1b) a second pressure (p.sub.1) at the purging air feed (15) that is lower than the first pressure (p) results from the adjusted flow (D.sub.1), the third flow (p.sub.at) and a flow resistance between the purging air feed (15) and the purging air discharge (24), the relative humidity (rF.sub.1) of the purging air being reduced by the relief of pressure from the first pressure (p) to the second pressure (p.sub.1).

The disclosure includes a welding cup system comprising a tube having an open top, an open bottom, a sidewall extending between the open top and the open bottom, and an open channel. The open channel may extend through an interior portion of the tube from the open top to the open bottom. The open top may be arranged and configured to slideably couple to at least a portion of a torch assembly. The open channel may be arranged and configured to allow gas to flow from the open top to the open bottom, and allow a welding electrode to extend through the open channel from open top towards the open bottom. The welding cup system may have a side profile that may define an asymmetrical shape.

A welding or additive manufacturing wire drive system includes a first spindle for a first welding wire spool, a second spindle for a second welding wire spool, a first drive roll, and a second drive roll. One or both of the drive rolls has a circumferential groove. A first welding wire and a second welding wire are located between the first drive roll and the second drive roll in the circumferential groove. The first welding wire contacts the second welding wire between the first drive roll and the second drive roll. The first welding wire further contacts a first sidewall portion of the circumferential groove. The second welding wire further contacts a second sidewall portion of the circumferential groove. Both of the first welding wire and the second welding wire are radially offset from a central portion of the circumferential groove.
