An automated welding system includes a support structure, a plurality of welding heads, and a controller. The plurality of welding heads are each removably, mechanically coupleable to the support structure. The controller is configured to control welding operations of the automated welding system based on an identity of a particular welding head of the plurality of welding heads that is mechanically coupled to the support structure and operably coupled to the controller.

Systems are disclosed relating to a mobile device mounted to a welding helmet such that a wearer of the welding helmet can see a display of the mobile device when wearing the welding helmet. In some examples, the mobile device is mounted such that a camera of the mobile device is unobscured and positioned at approximately eye level, facing the same way the wearer's eyes are facing. In some examples, the simulated training environment may be presented to the user via the display screen of the mobile device, using images captured by the camera of the mobile device, when the mobile device is so mounted to the welding helmet.

An example fluid container configured to receive a fluid, with a filler neck configured to channel the fluid from an inlet into the fluid container. In some examples, a flexible hose connects the fluid container to the filler neck.

A system and method for wirelessly controlling, monitoring, and updating various welding parameters from a remote device using a single remote control. The remote does not need to have the software to communicate with the welding-type system prior to initiating communications with the welding-type system. Rather, the welding-type system can provide a code download to the remote to perform an over-the-air programming of the remote to configure the remote to control the welding-type system.

A system, in one embodiment, may include a portable unit having an engine, a generator coupled to the engine, a compressor coupled to the engine, and a priority load controller. The controller may be configured to adjust various loads on the engine, the generator, or the compressor, or a combination thereof, in response to a priority control scheme. A computer-implemented method, in another embodiment, may include adjusting power output to various loads on an engine, a welding generator coupled to the engine, or an air compressor coupled to the engine, or a combination thereof, in a portable welding unit in response to a priority control scheme.

An example welding-type power supply includes: power conversion circuitry configured to convert three-phase input power to welding-type power; a reference node coupled to each winding of the three-phase input power via a corresponding impedance; and a phase detection circuit coupled to the reference node and configured to determine a number of phases connected to the input based on comparing a frequency of a signal at the reference node to a threshold frequency.

Apparatus and methods are provided for a welding-type power system that includes an engine configured to drive an electric generator to provide a first power output. An energy storage device to provide a second power output. A controller is configured to receive one or more control signals to provide a total power output to at least one of a welding-type output or an auxiliary type output, determine proportional values for the first power output and the second power output that add up to the total power output based on a power demand signal that indicates a contribution of the first power output and the second power output, control the engine to adjust speed based on the first power output value, and control a connection from the energy storage device to provide the second power output to the welding-type output based on the second power output value.

An object of the present invention is to appropriately perform a welding quality control. Therefore, a welding work data accumulation device (100) includes: a measurement unit (4, 5, 7, 9, 11, and 16) that measures a welding motion and a welding phenomenon when a welding operator (1) grips a welding torch (2) and performs welding on a welded body (3); a data analysis unit (14) that extracts an appropriate combination of a welding motion feature amount (Tw, Ht, and Sp) and a welding phenomenon feature amount (Iw, S, and Ssym) in correction with time or coordinates based on data acquired by the measurement unit (4, 5, 7, 9, 11, and 16); and a data accumulation unit (15) that creates a database (70) based on an extraction result of the data analysis unit (14).

Power electronics, including welding-type power supplies may have a switched mode power supply configurable in two or more topologies. Detection circuitry of the power electronics may determine the configured topology of the switched mode power supply and the input voltage supplied to the power electronics. The detection circuitry and/or control circuitry of the power electronics may verify that the configured topology of the switched mode power supply corresponds to the supplied input voltage, and may indicate an error if the configured topology does not correspond to the supplied input voltage.

Embodiments of a welding power supply include an engine adapted to drive a generator to produce a first power and a energy storage device adapted to discharge energy to produce a second power. The welding power supply also includes control circuitry adapted to detect a commanded output. The control circuitry is adapted to meet the commanded output by controlling access to power from the energy storage device to produce the second power when the commanded output is below a first predetermined load level. The control circuitry is further adapted to meet the commanded output by controlling access to power from the engine and the energy storage device to produce the first power and the second power when the commanded output is above a second predetermined load level.
