1.2MM SF-3A X 12.5KG D300 NITTETSU FLUX-CORED MIG WIRE GAS-SHIELDED

SF-3A is a seamless, rutile flux cored wire designed for welding of steel with impact requirements down to -40°C such as grade E often used in shipbuilding. The flux cored wire uses an Argon/CO2 mixed shielding gas which gives good weldability and a stable arc, minimum spatter, good visual bead, and even transition to parent material. Due to the seamless design, the wire has an extremely low hydrogen content, (typical of ≤2.8 ml/100g) which greatly reduces the possibility of cold cracks. SF-3A emits little welding fume and has great weldability in all 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 15-25mm depending upon the welding parameters. Voltage should be approx. 10% of the Ampere, which is 1-3 Volts lower than that of which conventional folded flux cored wires require.
