Quickly and easily weld up holes in sheet metal.
Use a MIG or TIG welder to fill holes in the middle of a panel with metal. Magnetic Backing Tool makes it easy to weld-shut a hole in the middle of a panel. With this versatile tool, you'll leave your 2 hands free for welding while the copper head backs-up that hole. Strong magnetic mount secures the adjustable 1-1/4"- diameter copper swivel back-up head up against the hole to be repaired.
Just attach to the back of a panel and adjust the arm to back up holes. Weld will not stick to the copper while also absorbing heat to minimise warpage.
