Electrode Holder KD500

The KD500 Electrode Holder is a professional-grade manual arc welding accessory engineered for the South African structural, mining, and heavy engineering sectors. Featuring a robust Screw-Type clamping mechanism, it is the primary choice for boilermakers who require an absolute, "no-slip" grip on heavy-gauge electrodes (3.2mm to 6.3mm). Rated for 500 Amps, this holder is the "powerhouse" for heavy-duty inverter and transformer machines, providing superior electrical conductivity and extreme heat resistance during high-amperage, continuous-duty welding.

Key Performance Features

• Heavy-Duty Brass Alloy Head: Manufactured from high-purity brass to ensure maximum current transfer and minimize "voltage drop," preventing the holder from overheating during thick-plate welding runs.
• High-Torque Screw-Action Grip: The twist-handle mechanism provides a mechanical "locking" force on the electrode, ensuring a stable arc even when working with heavy 5.0mm or 6.0mm low-hydrogen rods.
• Reinforced "High-Impact" Insulation: Encased in a flame-retardant, high-dielectric polymer shell that protects the operator from electrical shock and the intense radiant heat of a 500A arc.
• Precision-Machined Multi-Angle Seating: Features deep grooves in the brass head to lock electrodes securely at 45°, 90°, and 180° angles, providing maximum versatility for structural joints and heavy machinery repairs.

Ideal Applications

• Heavy Structural Steelwork: The industry standard for welding thick-walled I-beams, industrial trusses, and bridge components.
• Mining & Earthmoving Maintenance: Perfect for the high-amperage hard-facing and structural repair of excavator buckets and underground machinery.
• Heavy Agricultural Manufacturing: Ideal for fabricating heavy-duty multi-row plough frames, industrial grain trailers, and heavy tractor hitches.
• Foundry & Steel Mill Utility: A reliable primary tool for maintenance teams working in extreme heat environments with heavy-duty power sources.

Product Benefits

• Reduced Operator Fatigue: The balanced weight distribution and ergonomic twist-grip allow for comfortable use throughout full 8-hour industrial shifts.
• Extreme Service Life: With no external springs to lose tension or clog with spatter, the KD500 is built for the "dropped-on-site" reality of heavy construction.
• Secure High-Amperage Connection: Designed for a 100% tight fit with 50mm² to 70mm² welding cables, reducing heat build-up at the cable-to-holder joint.

Pro Tip: To ensure the longevity of your KD500, always keep the internal brass threads clean. In high-amperage environments (400A+), ensure the cable grub screws are checked weekly for tightness; a loose cable connection is the leading cause of handle "meltdown." When using 6.0mm electrodes, a quick twist of the handle provides far more clamping pressure than a standard spring holder, preventing "electrode-wobble."
