Weld Star A15 ER 70S-2 Wire [15kg Spool]

The Weld Star A15 (ER 70S-2) is a premium micro alloyed solid MIG wire specifically engineered for the most challenging carbon steel applications. What defines the A15 is its triple de-oxidised chemistry, containing a precise balance of Titanium (Ti), Aluminium (Al), and Zirconium (Zr). These elements act as scavenging agents, effectively neutralising surface impurities to produce X-ray quality welds on greasy, rusted, or mill scaled surfaces.

This wire is particularly favoured in the automotive and repair sectors for its ability to produce porosity free welds on galvanised steel and subsequent to various coating processes. Part of the "Green Wire" range, it is manufactured from high purity virgin raw materials, ensuring a stable arc and excellent mechanical properties down to -30ºC. Whether you are working on pipelines, naval vessels, or petrochemical tanks, the A15 provides the reliability needed when base metal conditions are less than perfect.

Key Features

Triple De-Oxidised (Ti, Al, Zr): Advanced scavenging agents eliminate porosity when welding over surface contaminants like light rust or oil.

Galvanised Steel Specialist: The best solid wire choice for welding zinc coated or galvanised metals with minimal spatter.

Superior Weld Pool Control: Offers a fluid yet controllable puddle, ideal for root runs in pipelines and structural work.

Extreme Cleanliness: Produced using virgin raw materials (Green Wire) to ensure consistent metallurgy and reduced contact tip wear.

Low Temperature Toughness: Maintains high impact strength (50 J) in cold environments down to -30ºC.

Precision Layer Wound: Guaranteed smooth feeding for both manual and automated high production environments.
