If you are considering this item as an alternative to more expensive magnetic grounds, allow me to save you the time and frustration. The magnet is very weak, and the "ground" portion depends on a tiny spring to keep it in contact with the work/ table. The result: no (or intermittant) arc at the electrode, and a giant explosive arc at the ground. Be safe- stay away from this product!

This magnetic ground lead attachment is very easy to attach to any steel being welded. It provides a strong attachment close to the welding point without becoming intrusive. It is much easier to use and more secure than clamp on ground points. It uses a 1/2" bolt as the attachment point for your ground lead, so the ground lug you use has to have a 1/2" hole.

The weight of the cable causes the contact to pull away from the surface I am welding on. I thought this would be better for the auto body work I am currently doing, but I had to switch back to the old grounding clamp from before
