The work clamp, also known as a ground clamp, establishes a secure electrical connection between the welding power source and the workpiece. It completes the electrical circuit, allowing current to flow for arc initiation and maintenance, and provides a safe ground path to prevent electrical hazards.
According to the directory reference, work clamps have a rated current of 300–600 A, as per IEC 60974-1. However, the exact rating depends on the specific model and must be confirmed with the manufacturer.
Selection should be based on the welding current required, the thickness of the workpiece (clamping capacity 1–30 mm), and the size of the welding cable (35–95 mm²). Also consider the duty cycle and operating temperature range. Always verify the specifications with the supplier.
Regularly inspect the contact surfaces for wear, corrosion, or damage. Ensure the spring force is adequate for a secure grip. Clean the contact points to maintain low resistance. If the clamp overheats or shows signs of arcing, replace it or have it serviced.
