Weld Star CF2 G3Si1 Wire [15kg Spool]

The Weld Star CF2 (G3Si1) is a premium, non copper coated solid MIG wire engineered for the high volume welding of unalloyed and carbon manganese steels. By eliminating the copper coating found on traditional wires, the CF2 significantly reduces the amount of copper vapor and smoke in the breathing zone, creating a cleaner and safer working environment for the welder.

This "Green Wire" is manufactured using virgin raw materials from specialised steel mills, ensuring consistent chemistry and high radiographic quality. The absence of copper flakes also prevents the clogging of liners and contact tips, leading to superior wire feeding and reduced maintenance downtime. With exceptional mechanical properties down to -40°C and a stable, spatter free arc, the CF2 is the definitive choice for structural engineering, shipbuilding, and automotive manufacturing where weld quality and operator health are priorities.

Key Features

Copper Free (Non Coated): Reduced fume and smoke levels compared to traditional copper coated wires, better for the environment and the operator.

Superior Feeding Performance: The absence of copper coating prevents "copper flaking" in liners and tips, ensuring smooth, uninterrupted feeding for manual and robotic setups.

High Purity "Green Wire": Sourced from virgin raw materials to provide consistent, reliable metallurgy in every spool.

Zero Spatter Arc: Achieves high quality, clean welds even at increased welding speeds, drastically reducing post weld clean up.

Extreme Cold Toughness: Delivers excellent impact strength (up to 90J) at temperatures as low as -40°C.

Moisture Protection: Supplied in vacuum sealed packaging with an alignment hole clip for perfect start up and long term storage reliability.
