Oerlikon Carbofil 1A description: CARBOFIL 1A is a general application welding wire electrode used for both single- and multipass welding. Weld metal impact toughness properties are down to -40C. CARBOFIL 1A is available with a wide range of packaging formats, from few kgs for small MlG/MAG welding equipments to high-quantity (max. 550 kgs drum) robotic application. The increased level of Manganese and Silicon scavenge oxides enhancing weld pool fluidity and stabilizing the arc, minimising weld metal spatter and resulting in a higher strength weld metal. Excellent weld bead appearance with an even contour finish and freedom from undercut.
