Applications

Joining and overlay welding of copper zinc alloys,low copper materials,also for an excellent wear resisting overlay welding on low and unalloyed steel as well as cast iron.For MIG overlay welding of large work pieces preheating is recommended.For multilayer welding on steels,pulsed arc welding is  recommended.Appropriate for MIG brazing of zinc coated sheets.
