Weld Star – A31|ER 80S-D2 TIG Wire (3.2mm) 5kg


SKU: 3010300284 Category: Tag: Brand:

Product Description

Features and Applications

A copper coated heat-resisting wire containing 0.5% molybdenum.

Weld deposit yields excellent quality and bead appearance on carbon and low-alloy steels.

Suitable for operating at high currents giving a stable arc with a low amount of spatter.

Recommended working temperatures of up to 500°C.

Typically used on creep steels for construction steam boilers, pressure tanks, gas pipes, shipbuilding sector, petrochemical industry, heat exchangers, building of cranes, bridges etc.

Green wire is produced using virgin raw materials sourced from specialised steel mills, which ensures consistent reliability and quality.
