OVERVIEW

Heavy-Duty Industrial Metal Removal

The Techniweld RK4000 is a premium K4000-style manual gouging torch designed for heavy-duty metal removal applications. Engineered to handle up to 1000 Amps, this torch is built for rigorous industrial environments including shipyards, steel fabrication plants, and foundries. It utilizes the air carbon-arc process to melt metal with an electric arc while simultaneously blowing away the molten material with a high-velocity jet of compressed air. This method is highly efficient for gouging, cutting, beveling, piercing, and flushing metal.

Constructed with high-impact, heat-resistant materials, the torch body is fully insulated to ensure operator safety and equipment longevity. The internal air valve is designed for optimal flow characteristics, ensuring that the air stream effectively clears molten metal from the groove, resulting in a cleaner cut and reduced cleanup time. The jaw assembly is robust, providing a secure grip on carbon electrodes ranging from 5/32-inch to 1/2-inch round, and up to 5/8-inch flat, preventing electrode slippage during operation.

A key feature of this assembly is the 7-foot heavy-duty cable. Unlike rigid cables that fight the operator, this unit features a 360-degree swivel connection at the torch handle. This significantly reduces wrist strain and operator fatigue during extended use, allowing for greater precision and control. The cable is encased in a durable outer sheath that resists abrasion, cuts, and heat, ensuring reliable performance in harsh shop conditions. Whether you are removing defective welds, preparing plate edges for welding, or removing casting risers, the RK4000 delivers consistent, high-power performance.

Technical Reliability and Compatibility

This torch is designed as a direct replacement for the industry-standard K4000, meaning it is compatible with standard replacement parts and consumables. This interchangeability simplifies inventory management and maintenance, as operators can use existing stocks of insulators, jaws, and lever assemblies. The torch requires a compressed air supply of approximately 80 PSI (5.6 kg/cm²) and 25 CFM (708 L/min) to operate at peak efficiency. It connects easily to standard welding power sources and air supplies, making it a versatile addition to any heavy industrial MRO toolkit.
