Purpose and function Heavyduty 400A earth clamp designed to provide a secure, lowresistance grounding connection for welding operations and earthing terminals. Stable electrical contact reduces welding defects caused by poor grounding and improves overall job safety. Key benefits (why you need it) conductivity brass body delivers consistent current flow and low contact resistance for reliable welds. Brass construction with oxidation resistance extends service life and reduces maintenance frequency. Special Gclamp design locks securely to workpieces and cabling, minimizing the risk of slippage or accidental disconnection during use. Rated for up to 400A to handle a wide range of welding currents used in industrial settings. Compatibility and applications Compatible with Argon arc welding, submerged powder welding, resistance welding, bolt welding and other common welding systems. Suitable for use as a rollout earthing terminal or permanent grounding clamp where dependable contact is required. Industries and typical uses Shipbuilding and shipyards: secure grounding for hull assembly and panel welding to reduce rework and maintain weld quality. Automotive manufacturing and accessories: reliable earthing for resistance welding lines and component assembly. Mechanical engineering and oil production: grounding for maintenance, fabrication, and onsite welding tasks. Electrical grounding terminals: safe, longlasting connection for earthing points and rollout terminals. Performance and reliability Durable brass material ensures good electrical performance even in corrosive or humid environments. Robust clamp geometry and firm grip lower the chance of interruptions during current welding. Designed for repeated industrial use with low wear on contact surfaces. What it solves Eliminates unstable grounding that causes spatter, inconsistent weld penetration, and equipment errors. Reduces downtime from clamp failures or frequent replacements. Improves operator safety by maintaining a secure connection during current operations. Specific scenarios Shipyard plate welding: attach the 400A earth clamp to hull sections to provide a consistent path for Argon arc or submerged arc welding, reducing porosity and improving seam integrity. Automotive assembly line: use the clamp as the grounding for resistance welding stations to ensure repeatable spot weld quality across volume cycles. Field service on oil production equipment: clamp onto structural frames or designated earthing points for safe, corrosionresistant grounding during onsite repairs and bolt welding. Materials and specifications Body material: quality brass — good conductivity and oxidation resistance. Clamp type: special Gclamp design for secure attachment. Current rating: 400A suitable for a broad range of industrial welding applications. Ordering notes Intended for use with standard welding equipment and earthing terminals; confirm fit with your cable and terminal sizes as needed.
