High reliability modular welding power supply system
Embodiments of modular-based power supply systems to support welding or cutting operations are disclosed. One embodiment includes a module rack having multiple slots configured to accept electrical input power from a single power drop within a welding or cutting environment. Multiple power supply modules are provided that are configured to be inserted into and withdrawn from the multiple slots. Each power supply module is configured to accept an electrical AC input derived from the electrical input power and provide an electrical DC output. The module rack is configured to support reconfigurable parallel electrical connections of subsets of the power supply modules. Each subset is configured to electrically connect to an output power supply stage to provide a dynamic waveform-controlled welding or cutting electrical signal to support generation of a single arc between an electrode and a workpiece.
