61082009 - Arcair K4000 Extreme Gouging Torch & 10ft Cable Kit

Heavy-Duty Air Carbon Arc Gouging Performance

The Arcair K4000 Extreme Heavy-Duty Torch and Cable set (SKU: 61082009) represents the industry standard for manual air carbon arc gouging. Engineered by Victor Arcair, a leader in metal removal technologies, this torch assembly is designed to operate efficiently at amperages up to 1000 A. The K4000 system utilizes the heat of a carbon arc to melt metal while a simultaneous stream of compressed air blows the molten metal away, leaving a clean groove ready for welding or repair.

Optimized Pneumatic and Electrical Design

This assembly features a 10-foot (3 meter) cable hose that is critical to the system's performance. The cable is constructed to offer high heat and abrasion resistance, ensuring longevity in harsh shop environments. The hose is non-conductive, providing an essential safety layer for the operator. Pneumatically, the torch requires a compressed air supply of 80 psi (5.6 kg/cm²) and consumes approximately 28 cfm (0.79 m³/min) to effectively clear molten material. The internal air flow design of the K4000 Extreme has been optimized to improve metal removal rates compared to older models.

Electrode Compatibility and Versatility

The K4000 is highly versatile regarding consumable compatibility. It is designed to accept pointed copper-clad carbon electrodes ranging from 5/32 inch (4.0 mm) to 1/2 inch (12.7 mm) in diameter. For applications requiring wider grooves, it accommodates flat carbon electrodes from 3/8 inch (9.5 mm) to 5/8 inch (15.9 mm). This range allows the K4000 to be used for a variety of tasks, from light defect removal to heavy-duty weld preparation and casting finishing.

Ergonomics and Construction

Weighing approximately 7.6 lbs (assembly weight), the torch is built for durability but balances this with ergonomic features. The 15-degree natural angle of the torch head works in conjunction with the movement of the operator's arm, facilitating a smooth gouging action. The inclusion of a 360-degree swivel cable significantly mitigates cable twist, a common issue that leads to operator wrist strain. The rugged construction ensures that the torch withstands the thermal and mechanical stresses inherent in high-amperage gouging.
