A work clamp, sometimes referred to as an earthing clamp, is an essential part of the welding process. It creates an electrical connection between the object to be welded and the welding equipment. In order to ensure that the current flows correctly and safely throughout the welding operation, this connection is necessary to complete the welding circuit.

High-quality welds and continuous, efficient operation in a variety of welding processes depend on the use of welding earthing clamps.
