Clamp G TYPE Half Brass 600 AMP Heavy Duty

The 600A G-Type Earth Clamp is a premium, high-amperage grounding solution engineered for the most demanding South African industrial environments. Featuring a Half-Brass body construction, it is the primary choice for professional boilermakers and site contractors who require a secure, low-resistance electrical circuit for heavy-duty MIG, MMA (Stick), and Submerged Arc welding. Unlike standard spring-loaded clamps, the G-clamp design uses a precision screw-thread mechanism to provide a "crushing" grip, ensuring a 100% stable arc even on thick-gauge structural beams and heavy plate work.

Key Performance Features

• High-Conductivity Half-Brass Body: The lower jaw and main body are cast from a high-purity brass alloy, significantly reducing electrical resistance and preventing the "voltage-drop" common with steel-bodied clamps.
• 600A Industrial Capacity: Specifically engineered to handle the high heat and current flow of 400A–600A welding cycles without the clamp body overheating or "fusing" to the workpiece.
• Heavy-Duty Screw-Thread Mechanism: Features a large-diameter, copper-plated screw with a heavy-duty T-handle, allowing the operator to apply massive clamping force for a vibration-proof connection.
• Copper-Wash Grounding Point: Equipped with a dedicated, heavy-duty terminal point and copper sleeve to ensure a secure, low-heat connection for 50mm² to 70mm² welding cables.

Ideal Applications

• Heavy Structural Fabrication: The industry standard for grounding I-beams, columns, and heavy-duty trusses where a reliable arc is critical for x-ray quality welds.
• Mining & Earthmoving Repair: Perfect for high-amperage maintenance on heavy-duty buckets, chassis components, and specialized underground mining machinery.
• Shipbuilding & Marine Engineering: Provides the robust electrical contact needed for thick-walled hull welding in high-moisture or corrosive environments.
• Automated & Robotic Welding Cells: Ideal for stationary welding tables where a permanent, high-conductivity ground is required for consistent automated performance.

Product Benefits

• Reduced Arc-Blow: By providing a superior, direct electrical path, this clamp helps minimize "arc-blow" and instability, resulting in cleaner weld beads and less spatter.
• Extreme Durability: The heavy-cast brass and reinforced steel components are designed to withstand the "Highveld-abrasion," spatter, and mechanical impacts of a busy industrial workshop.
• Universal "C-Clamp" Versatility: The wide jaw opening allows the clamp to be attached to various profiles, including thick plate edges, angle iron, and large-diameter piping.

Pro Tip: To maintain the full 600A capacity, always ensure the brass contact face of the clamp is free from spatter and oxidation. A quick pass with a wire brush or file before attachment ensures a clean metal-to-metal contact. For the best performance on heavy structural work, place the clamp as close to the welding joint as possible to reduce the "path of resistance" and prevent the cable from running hot.
