SYSTEMS AND METHODS FOR PROVIDING POWER FOR PLASMA ARC CUTTING

A plasma cutting system includes a plasma torch having a head, and a housing. A power supply is disposed within the housing and is in communication with the plasma torch. The power supply is configured to provide an output current for generating and maintaining a plasma cutting arc by the plasma torch, and includes a control processor in communication with a plurality of autonomous switching circuits via a multi-node communications bus. Each of the autonomous switching circuits includes a microcontroller configured to control the generation of a portion of the output current based on messagesreceived from the control processor, monitor operating parameters of the autonomous switching circuit, and modify a control parameter of the autonomous switching circuit independent of and asynchronous to the other autonomous switching circuits of the plurality of autonomous switching circuits when one or more of the operating parameters exceeds a predetermined threshold. 等离子切割系统包括具有头部的等离子焊炬和壳体。电源设置在壳体内并且与等离子焊炬通信。电源被配置成提供
