Simply put, the welding module is a welding control without integrated operation. The welding module has one or more interfaces to a separate operation. This can be a control unit or a computer. Typically, welding modules are networked so that the modules can be parameterised and monitored via a central control unit, the control PC.
Examples of welding modules are the Ratia73 modules for mains frequency applications and the GeniusMFI modules in the medium frequency world. With the inverters of these medium-frequency systems, there is also the special feature that the welding modules have the power sections integrated. The central operation is realised via an operating software. For the aforementioned systems, this is XPegasus. With older welding modules such as the MPS 9173, these were the WinZSPS or Pegasus interfaces. In addition to central operation, the welding modules can also be parameterised and operated via separate control panels. These are either mobile notebooks or tablets or built-in operating devices such as the Xcomand system.
With welding modules, medium to large systems with several welding points can be equipped cost-effectively and flexibly.
