Magnaloy Weld Pad Kits are designed for use with Magnaloy's Weld Style Dampening Bars. Welding directly to the Magnaloy Motor Dampening Bar can cause damage to the metal-to-rubber bond resulting in premature failure. Welding should be limited to the ends only (across the W dimension) to prevent damage to the rubber vulcanization by the heat generated during the welding process. Extreme care should be exercised whenever welding to assemblies containing vulcanized rubber. Bond Separation will occur if the metal/rubber surface interface reaches a temperature above 500F.
