QB-800A Air Carbon Arc Gouging Torch 800A Heavy Duty Carbon Gouging Gun for Weld Root Back Gouging

QB-800A Air Carbon Arc Gouging Torch

This QB-800A air carbon arc gouging torch is an upgraded heavy-duty handheld gouging tool for industrial welding repair and metal removal jobs. It works with DC welding power source and compressed air. The conductive part adopts high-conductivity brass for stable current transmission, with built-in air regulating switch to easily control air flow.

✅ Key Features

• 800A heavy-duty rating, supports long continuous gouging work, higher efficiency than QB600A model
• High purity brass conductive assembly, low heat generation, excellent conductivity
• Built-in air control knob, convenient to adjust air volume on site
• Optimized air channel, concentrated strong airflow, quickly blows away molten slag
• Ergonomic insulated anti-scald handle, non-slip grip for comfortable long-time operation
• Fast carbon rod clamping and replacement, easy maintenance, durable for harsh workshop conditions
• Compatible with round carbon gouging rods from Φ4mm to Φ10mm

✅ Main Applications

• Weld root back gouging for shipbuilding, pressure vessel, pipeline and thick plate welding
• Remove weld defects such as cracks, slag inclusion and porosity for weld repair
• U-groove preparation before heavy welding
• Remove excess weld reinforcement
• Clean casting gates, risers and burrs on castings
• Grooving, rough metal removal for carbon steel, stainless steel, alloy steel and cast iron

✅ Working Requirements It must be matched with DC welding machine (DCEP, direct current electrode positive) and compressed air supply.
