Description
Weld Star – A31 (ER 80S-D2) Wire (0.8mm) 15kg
Weld Star – A31 (ER 80S-D2) is a copper-coated wire designed for welding applications that require heat resistance. It contains 0.5% molybdenum, which contributes to its excellent welding properties. This wire is particularly suitable for high current operations, producing a stable arc with minimal spatter. It is recommended for use at temperatures up to 500°C.
Key Features:
- Copper-Coated Wire: Contains 0.5% molybdenum for heat resistance.
- Weld Quality: Produces excellent bead appearance on carbon and low-alloy steels.
- High Current Operations: Offers a stable arc with minimal spatter.
- Precision Layer Wound: Ensures superior wire feeding characteristics.
- Virgin Raw Materials: The green wire is produced using virgin raw materials from specialized steel mills for consistent quality and reliability.
