Applications

Suitable for welding of copper materials,for example copper and tin bronzes,especially used for joining of copper zinc alloys and steels. Also suitable for repair welding of cast bronzes.For large work pieces preheating is recommended.For multilayer welding on steel,pulsed arc welding is recommended-also appropriate for oven soldering.
