Technology

Overview
Similar to plasma cutting, plasma gouging removes metal using a plasma arc formed between the torch and the workpiece. In this process, surface metal is melted and ejected by a high-velocity gas stream — without piercing or severing the workpiece. The torch is held at an angle, and specific gouging consumables create a broader arc to remove only part of the material.

Most modern plasma cutters offer a dedicated gouging mode that optimizes gas pressure. While gouging is possible in cutting mode, it is recommended to use gouging-specific nozzles and shields to prevent accidental piercing and ensure a clean result.

Key benefits of plasma gouging:

• Compatible with all conductive metals: mild steel, stainless steel, aluminum, copper...

• Faster process with reduced grinding and finishing time.

• Quieter operation and less debris compared to carbon-arc gouging.

• Free of carbon contamination – ideal for clean weld prep.

• Safer than oxyfuel and carbon-arc gouging methods.

• Easier to learn and faster operator training.

• Effective spot weld removal for high-strength automotive body panels.

Versatile application: Plasma gouging can be done freehand, with a track system, or on CNC tables, making it ideal for repair, maintenance, and production applications.
