IMPA: 851045

Screw-on Earthing Clamp for Marine Welding | IMPA 851045

This screw-on type earthing clamp (IMPA 851045) is an essential grounding accessory for marine welding operations. Designed to establish a solid electrical connection between the welding cable and the workpiece, it ensures a stable circuit and prevents welding defects caused by poor grounding. Its robust construction and screw-on mechanism provide a firm, adjustable grip on steel plates, pipes, and other ferrous surfaces commonly found aboard ships and in dockyards.

Manufactured from high-conductivity copper alloy with a steel screw assembly, this earthing clamp delivers excellent current transfer and long service life in harsh maritime environments. The screw-on design allows quick attachment and removal, making it ideal for temporary welding setups during ship repair, fabrication, and maintenance. The clamp accommodates welding cables of various sizes and offers a wide clamping range to suit different workpiece thicknesses.

As a vital piece of welding equipment for marine ship chandlers, this clamp meets the demands of professional welders and shipyard technicians. Order your IMPA 851045 screw-on earthing clamp today to ensure efficient, safe, and high-quality welding results onboard and ashore.

Frequently Asked Questions

What is the purpose of an earthing clamp in welding?

The earthing clamp (ground clamp) provides a solid electrical connection between the welding machine and the workpiece, completing the circuit and ensuring safe, effective welding. It also dissipates heat and prevents electrical shocks.

What size welding cable does this screw-on clamp accept?

This clamp accepts welding cables up to 35 mm² (2 AWG). It features a screw terminal for secure cable attachment.

Can this earthing clamp be used on painted or coated surfaces?

For optimal conductivity, the clamp should be attached to clean, bare metal. Painted or coated surfaces may interfere with the electrical contact and should be cleaned before clamping.

How do I maintain this earthing clamp for long service life?

Regularly clean the contact surfaces and screw threads to remove dirt and oxidation. Inspect the cable connection and replace worn parts as needed. Keep the clamp in a dry place when not in use.
