bercoweld K8

Range of application

bercoweld K8

Copper wire (rod), silver- alloyed, with a slightly higher percentage of phosphorus, suitable for TIG- and gas welding. Good flowing properties of the welding material. High electric conductivity, viscous weld pool. Preheating for wall thicknesses of more than 3 mm (approx. 100°C for every mm of sheet thickness, not more than 600°C
