NITTETSU SF-3AM FLUX-CORED MIG WIRE

SF-3AM is a seamless rutile flux cored wire for welding using Argon/CO2 mixed shielding gas. This ensures a stable welding arc with less spatter, excellent visual bead shape and smooth transition to the base material. SF-3AM has acceptable Charpy impact values down to -60°C. The flux cored wire is CTOD-tested with good results. Due to the seamless design, the wire has an extremely low diffusible hydrogen content (typical 3 ml/100g), which greatly eliminates the risk of hydrogen cracks. SF-3 AM has low visible welding fumes and has excellent weldability in all welding positions. The wire has a clean copper coated surface, which, together with exact diameter and roundness, ensures stable and even wire feeding. Wire stick out should be between 15-25 mm depending upon welding parameters. Voltage should be about 10% of the Ampere, which is about 1-3 Volts lower than that of which conventional folded flux cored wires require.
