Apparatuses, systems, and/or methods for providing an induction heating system are disclosed. The induction heating system includes an induction power supply and an induction heating tool configured to receive induction-type power from the induction power supply through one or more ports. The ports may be part of the induction power supply and/or an associated junction box. The induction heating tool may include a heating coil attached to one or more plugs via one or more cables. The ports of the induction power supply and/or junction box are configured to receive the plugs of the induction heating tool. A communication device may be positioned adjacent the ports. The communication device may be configured to read data from one or more memory devices of the induction heating tool (e.g., in/on the plugs) via close proximity communication.

Embodiments described herein include wireless control of a welding power supply via portable electronic devices, such as dedicated original equipment manufacturer (OEM) welding remote devices, cellular radio telephones, satellite radio telephones, laptops computers, tablet computers, and so forth. In particular, operating parameters and statuses of the welding power supply may be modified by the portable electronic device, as well as be displayed on the portable electronic device. A pairing procedure may be used to pair the welding power supply and the portable electronic device in a wireless communication network. Furthermore, in certain embodiments, a method of providing location services for the welding power supply includes utilizing location data for the portable electronic device controlling the welding power supply as an approximation for the location of the welding power supply.

Systems and methods to control auxiliary power output voltage using a welding output voltage are disclosed. An example power system includes an engine, a generator to provide electrical power based on mechanical power received from the engine, the electrical power comprising welding-type power and non-welding power, and a controller to control the generator or the engine to increase or decrease a voltage of the non-welding power based on a voltage measurement of the welding-type power.

Embodiments of welding systems and methods with coordinated dual power outputs supporting a same welding process or a same AC output process are disclosed. One embodiment of a welding system includes an engine and a generator operatively connected to the engine, where the engine is configured to drive the generator to produce electrical input power. The welding system also includes a power supply operatively connected to the generator and having at least one controller. The power supply is configured to convert the electrical input power to form two power outputs that are coordinated with each other, at least in time, via the controller to support a same welding process. The same welding process may be, for example, a hotwire welding process, a tandem metal inert gas (MIG) welding process, or an alternating current (AC) output process.

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.

A welding apparatus is configured to obtain values of one or more real-time operating parameters associated with the welding apparatus. Using the values of the one or more operating conditions, the welding apparatus is configured to determine a dynamic duty cycle of the welding apparatus, given the present/current operating conditions of the welding apparatus.

Methods and apparatus to communicate via a weld cable are disclosed. An example welding accessory includes a first port to receive input power via a first weld cable, a power converter to convert the input power to output power, a second port to output the input power via a second weld cable, and one or more output switches to selectively divert the input power from the power converter to the second port.

A system and device operating using a welding power bus are provided. One welding power supply includes control circuitry configured to control the operation of the welding power supply and power conversion circuitry configured to convert input power to output welding power. The welding power supply also includes welding terminals configured to receive the output welding power from the power conversion circuitry and to provide the output welding power to a device that does not use the welding power for a welding operation. The control circuitry is configured to adapt the output welding power to the device.

The disclosed technology generally relates to welding technologies and more particularly to electrode assemblies for arc welding, e.g., submerged arc welding. In one aspect, an electrode assembly for submerged arc welding comprises a contact tip portion and an extension portion arranged serially and configured to feed a consumable electrode therethrough. During welding, the contact tip portion is disposed to be distal to an arcing tip of the consumable electrode and the extension portion is disposed to be proximal to the arcing tip of the consumable electrode. The extension portion is configured to electrically insulate the consumable electrode from a work piece during welding with a solid insulating material surrounding the consumable electrode.

The disclosed technology relates generally to welding technologies and more particularly to electrode assemblies for arc welding, e.g., submerged arc welding. In one aspect, an electrode assembly for submerged arc welding (SAW), the electrode assembly comprising a head portion comprising a contact nozzle and an extension portion removably and serially attached to the contact nozzle and disposed to be proximal to an arcing tip of a consumable electrode relative to the contact nozzle. The extension portion comprises a ceramic sleeve configured to slidingly feed the consumable electrode therethrough, and a pair of metallic sheaths covering opposing ends of the ceramic sleeve.
