The WIA Austfil Excel 71LF Flux Cored Wire, 1.6mm in a 200kg drum, is a high-performance rutile flux cored welding wire engineered for professional welders and fabricators. Designed for all positional welding, it delivers optimal results with both Argon/CO2 and pure CO2 shielding gas mixtures, making it suitable for a wide range of industrial applications.

This wire is ideal for welding mild, carbon, and carbon-manganese steels where reliable impact properties are essential. Its formulation ensures a smooth arc transfer and a wide operating window, allowing for ease of use in various welding positions and environments. The high deposition rate and forgiving parameter range make it especially effective for heavy fabrication, structural steelwork, truck body manufacturing, shipbuilding, earthmoving equipment, storage tanks, and bridge construction.
