Earthing Clamps - ARC Welding Accessories

Earthing clamps are essential accessories in arc welding systems, designed to provide a secure and reliable ground connection between the welding power source and the workpiece. The GCL series earthing clamps are engineered for durability, safety, and excellent electrical conductivity across a range of welding applications.

Made from high-conductivity copper or brass alloys, these clamps ensure minimal voltage drop and consistent arc stability. Their robust spring mechanisms maintain strong clamping pressure for firm contact with various surfaces, including flat plates, pipes, and structural elements.

Each model in the GCL range is rated for a specific current capacity, with heat-resistant components and corrosion-resistant finishes. These clamps are compatible with a wide range of welding cables, ensuring flexibility and reliability even in demanding industrial environments.

⚠️ Caution – Safe Use of Earthing Clamps

To ensure safe and reliable operation of GCL series earthing clamps, follow these important guidelines:

Safety Guide – Earthing Clamps (GCL Series)

Earthing clamps are critical components in arc welding setups. Follow the safety instructions below to ensure safe, efficient, and long-lasting operation.

  1. Use of Protective Gloves
  • Always wear properly insulated welding gloves when handling earthing clamps.
  • Gloves protect the user from electric shock, high temperatures, and sharp edges.
  • Never operate the clamp with bare hands during or immediately after welding.

 

  1. General Usage Caution
  • Use only the clamp model rated for the welding current you intend to apply.
  • Ensure the clamp forms a clean and solid connection with the workpiece.
  • Avoid contact with painted, rusted, or oily surfaces, as these reduce conductivity.
  • Adhere strictly to the rated duty cycles:
    • 35% duty cycle: Operate up to 3.5 minutes in any 10-minute period.
    • 60% duty cycle: Operate up to 6 minutes in any 10-minute period.
  • Inspect clamps regularly for wear, corrosion, or mechanical damage.
  • Always turn off the welding power source before connecting or disconnecting the clamp.
  • Avoid using earthing clamps in wet or humid environments to reduce electric shock risk.

 

  1. Insulation Safety
  • Do not tamper with or remove the insulation on any part of the clamp.
  • Inspect insulation before each use. Cracks, burns, or wear can expose conductive parts.
  • Never attempt to repair damaged insulation with electrical tape or substitutes.
  • Replace any clamp with damaged insulation using original, manufacturer-approved parts.
  • Do not use clamps in wet areas unless they are specifically rated for such conditions.
