Brazing Instructions

Brazing Techniques: Clean the surface and preheat heavy sections. For thin flowing, adjust the torch to 3X carburizing and preheat to a higher temperature. Once the piece is preheated simply allow some of the flux to melt off the rod. When the flux flows through the joint melt off some of the alloy and keep the torch moving constantly until the alloy flows throughout the joint.
