The invention of the present disclosure avails to those in the field of welding a dual power-dual arc welder generator that allows for the separation of an ICE-powered generator from a connected welding machine, which has not been achieved previously. Currently, welding machines of ICE-powered systems may not be decoupled from the generator for use with local primary electrical power is available, and the generator is cannot power a dual arc system. The invention includes a plurality of inverter power welding machines, such as two for a dual arc system, wherein each inverter power welding machine is powered by a single ICE-powered generator. This enables a user of the system to power two welding machines using a single ICE-powered generator, which in turn enables the use of less equipment for dual arc welding in areas where primary electrical power is not available.

The present application relates to an arc welding arrangement and an electric arc welding method to be used with the arc welding arrangement. The arc welding arrangement comprising a first power source, a first electrode connected to say first power source, and a second electrode, said first electrode being adapted to generate a weld pool via a first electric arc present within a first arc region. The second electrode is operated at welding parameters adapted to ensure that excess energy from at least said first electrode is required to maintain said second arc ignited. The method comprises the step of feeding said second electrode so that it is allowed to consume excess energy from said first electrode to maintain said second arc ignited.

A method and apparatus for providing welding type power on one of at least two output terminals is disclosed. Input power is received and welding type power is derived and provided by a shared power circuit. The welding type power is provided across a shared terminal and only two process terminals in response to a desired process. The desired process can be set by user input, feedback, or sensing working connections. The process terminal is selected by selectively opening and closing at least two controllable switches.

Systems and methods for controlling an engine driven power system and/or a welding system from two or more control sources are disclosed. In some examples, multiple control devices or sources are in communication with a central control circuitry of the engine driven power system, and/or a welding system which is capable of managing commands from multiple control sources by prioritizing commands and/or limited the scope of control. In some examples, the central control circuitry controls the multiple control sources to update systems and displays to harmonize commands and/or data that originated at another source.

Embodiments of welding machines and methods for switching between electrically isolated welding output studs. One embodiment of a welding machine includes multiple welding output studs, a work stud, a contactor circuit, touch sense circuitry, and a contactor controller. The contactor controller is configured to determine that electrical contact has occurred between a first welding output stud of the multiple welding output studs and the work stud via the touch sense circuitry. The contactor controller is also configured to deactivate welding output power to other welding output studs of the multiple welding output studs via the contactor circuit based on determining that the electrical contact has occurred. The contactor controller is further configured to activate welding output power to the first welding output stud via the contactor circuit after deactivating the other welding output studs based on determining that the electrical contact has occurred.

Systems and methods for an example modular welding systems having one or more system capabilities based on components connected to the welding systems are provided. In some examples, a modular welding system includes one or more components, such as a welding power supply, one or more welding torches, a wire feeder, and/or an auxiliary device, each of which can be coupled to one or more of the other components

A welding system includes a multi-process power supply, a TIG torch, and a TIG power pin for connecting the TIG torch to the multi-process power supply. The multi-process power supply has a power output connection for a MIG torch and a controller. The Controller is configured to command shielding gas and welding current to be provided to the power output connection, and the power output connection is configured to provide the shielding gas and the welding current to a MIG torch when the MIG torch is connected to the power output connection. The TIG power pin connects the TIG torch to the power output connection such that the power output connection is configured to provide the shielding gas and the welding current to the TIG torch. The controller is configured such that at least one of the shielding gas and the welding current is not provided to the TIG torch through the power output connection until a user engages a control member.

A method of projection welding hardware to a plated steel sheet for hot stamping, may include pressing hardware and a plated steel sheet in a state in which a welding projection on the hardware is in contact with the plated steel sheet, supplying a primary current to the hardware and the plated steel sheet in a state in which they are pressed, and supplying a secondary current to the hardware and the plated steel sheet.

A simulator facilitates simulated welding activity of simulated weld joints. The simulator may include a logic processor based system operable to execute coded instructions for generating an interactive welding environment in which a welding activity is simulated, the welding activity occurring at an interface of a first simulated work piece and a second simulated work piece that defines a simulated weld joint. The simulator is capable of simulating the simultaneous welding of multiple users on the simulated weld joint in real time. The simulator is capable of simulating the removal of material from the work piece(s). The simulator is capable of simulating the traversal of a weld path corresponding to the simulated weld joint, with the weld path including linear and/or non-linear portions. The simulator is capable of simulating the generation of smoke during the simulated welding activity.
