Magnetic Hole Plug Welding Tool

Product Review (submitted on June 11, 2014):

This is a great idea. I use it often to weld up small cracks or fill holes in sheet metal. Some times, the use of a clamp on the back helps hold it tighter. Using copper as a backup works very well on thin metal. Lets you get good penetration without blowing through.
