Heavy Duty Screw Type Welding Ground Clamp with Solid Copper Jaw Earth Clamp for MIG TIG Arc Welding

Welding Ground Clamp 400A / 500A Heavy Duty Copper

Professional screw-type welding ground clamp with a solid copper jaw, engineered for a stable earth connection on MIG, TIG and arc welding machines. The copper contact face keeps the return path at low resistance, so the clamp does not heat up under sustained current.

• Stable Earth Connection - Solid copper contact jaw keeps the earth path at low resistance and the clamp cool under sustained current.
• Heavy-Duty Spring Tension - Reinforced screw tension holds the clamp firmly on sheet, plate and pipe workpieces without slipping.
• Multiple Jaw Styles - Available in A-type, C-type and Holland-type patterns rated from 300A to 800A, covering most workshop requirements.
• Fits Most Welding Machines - Standard bolt and screw terminals accept standard earth leads and work with MIG, TIG and arc welding equipment.

Fitment must be verified against the serial number and parts manual of the specific machine before ordering. This is a direct-replacement spare part and is not a genuine original part.
