630Amp Portable Carbon ARC Gouging Inverter Manual Welding Machine – Top China Suppliers & Reliable Factory Performance
Detailed Information
What Is Air Carbon Arc Gouging?
Air carbon arc gouging is a thermal cutting process of removing or severing metal by heat from a carbon arc. The process uses a carbon/graphite electrode, standard power source, and compressed air. The intense heat arc produced between the tip of the electrode and the metal workpiece melts and cuts the metal. The air carbon arc gouging technique is used to remove any old or defective welds for repairing or dismantling equipment.
How Does Air Carbon Arc Gouging Technique Work?
The air carbon arc gouging process involves striking the electrode tip on the surface of the metal workpiece. This creates an intense arc between the carbon electrode tip and the workpiece. The heat from the carbon arc cuts and melts the metal. The compressed air stream is then used for blowing the molten metal from the surface of the metal workpiece. The metal gets cut or gouged only along the direction of airflow.
