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 tool to the back of the panel to be repaired and adjust the arm to back-up a hole up to 1" in diameter. Weld-deposited metal will not stick to the paddle, and the copper helps absorb heat to minimize warping. Limited lifetime mfr's. warranty.
