Weld Star SG2 (G3Si1) Wire [15kg Spool]

The Weld Star SG2 (G3Si1) is a high performance, copper coated solid wire engineered for the most demanding professional environments. Known as "Green Wire," it is produced using premium virgin raw materials sourced from specialised steel mills, ensuring consistent metallurgical reliability and X-ray quality results in every spool.

Whether you are performing single pass or multi pass welding on unalloyed and low alloyed carbon-manganese steels, this wire delivers exceptional mechanical properties, including high impact strength even at sub-zero temperatures (-40ºC). Each 15kg plastic D300 spool is precision layer wound to eliminate snags and is vacuum sealed in aluminium foil to prevent moisture absorption, ensuring factory fresh performance from the moment you open it.

Key Features
