Applications

Particularly suitable for MIG brazing of zinc coated sheets in the car engineering,good flowing properties of weld pool,low tendency to porosity and spatter,also suitable for welding of zinc alloys, large work pieces preheating is recommended.For multilayer welding  low alloyed copper,for low and unalloyed steels and cast iron.For large work pieces preheating is recommended.Ideal for the use in car body making.
