A system includes a welding torch, a welding power supply unit, a remote device, and control circuitry. The welding power supply unit is configured to supply power to the welding torch. The remote device is coupled between the welding torch and the welding power supply unit. Additionally, the remote device is configured to detect a polarity of a welding operation. The control circuitry is configured to determine if the detected polarity is appropriate based on one or more welding parameters. Further, the control circuitry is configured to adjust the polarity of the welding operation.

Remote polarity detection and control for welding process

A welding device for remotely controlling welding power supply settings is provided. One embodiment of the welding device includes a welding pendant having a control panel configured to control a plurality of settings of a welding power supply. The control panel is not part of the welding power supply and the plurality of settings includes a welding current output by the welding power supply. The welding pendant also includes a welding power input configured to receive welding power and data from the welding power supply via a welding power cable. The welding power is combined with the data such that the data is provided over the welding power cable.

Welding device for remotely controlling welding power supply settings

There is provided a system and method for quick identification and selection of torch processes based on a profile scheme. In an illustrated embodiment, a profile selectable via a one-click process may define operational parameters for one or more torch processes. Multiple profiles may be identified by corresponding labels that are visible on the face of the system. Furthermore, in an illustrated embodiment, the profiles and associated torch processes may be automatically stored in the system upon user configuration of the operational parameters. For example, in one embodiment, the user may select a profile and configure a welding process. Upon changing an operational parameter, it may be automatically saved to the selected profile and process. Reselection of that profile may recall the last used process and its associated parameters. The operational parameters of other configured processes may then be retrieved by selecting the desired process within the selected profile.

Personalized interface for torch system and method

A welding wire feeder includes a welding wire feed drive configured to drive welding wire towards a welding application and wire feed control circuitry coupled to the welding wire feed drive. The wire feed control circuitry is also configured to control the drive of welding wire towards the welding application. The welding wire feeder also includes power conversion circuitry and welding process control circuitry coupled to the power conversion circuitry. The power conversion circuitry is configured to receive input power from a welding power source and to convert the input power to controlled waveform welding output. The welding process control circuitry is configured to provide control signals for conversion of the input power to the controlled waveform welding output. The welding wire feeder also includes a process operator interface coupled to the welding process control circuitry and configured to permit operator selection of a controlled waveform welding process.

Controlled waveform welding wire feeder system and method

A welding power supply unit includes an outer enclosure having a plurality of sides that encompass internal components of the welding power supply unit. The welding power supply unit also includes a roll cage assembly having a plurality of roll bars. Each roll bar is disposed generally parallel with, but not adjacent to, an edge of a side of the outer enclosure and external to the outer enclosure. At least two of the roll bars are associated with handle portions that rotate with respect to the respective roll bar. Each handle portion includes an extruded tubular aluminum bracket or a die cast aluminum bracket disposed around its respective roll bar. In addition, the welding power supply unit includes a plurality of fastening mechanisms attached to the outer enclosure, the fastening mechanisms securing the roll cage assembly to the outer enclosure.
