Now it’s easier than ever to use your MIG or TIG welder to fill that hole in the middle of a panel with metal! This versatile tool features a strong magnetic mount and an adjustable 1-1/4″ diameter copper swivel back-up head. Just attach to the back of the panel to be repaired and adjust the arm to back up holes up to an inch in diameter. Weld deposited metal will not stick to the paddle and the copper helps absorb heat to minimize warpage. Limited lifetime manufacturer’s warranty. Imported.
