Abstract

An automated plasma cutting system is provided that includes a positioning system mounted to a support, an automated plasma arc torch mounted to the positioning system, and at least one power supply operatively connected to the automated plasma arc torch. The power supply may provide electrical power and fluid flow to the automated plasma arc torch for operation. The system further includes a controller in communication with the automated plasma arc torch and the power supply, and an auxiliary plasma arc torch operatively connected to the power supply, wherein the power supply provides electrical power and fluid flow to both the automated plasma arc torch and the auxiliary plasma arc torch. The automated plasma arc torch may process the workpiece to generate a set of features, while the auxiliary plasma arc torch may process/cut a residual framework of the workpiece remaining after formation of the set of features.
