Application:
PHOENIXWELD HW751 fllux is acid flux. It can transit Si and Mn to the weld bead. It is insensitive to a small amount of rust and oxide scale and it has strong anti-porosity capability, which makes it especially suitable for the occasion when the base metal is not strictly cleaned before welding. It has good weld bead appearance, excellent slag removal and it is especially suitable for the high-speed fillet welding with double wire and multi-wire. It has excellent welding performance, stable arc combustion. The maximum welding current can be 1000A. It can weld low carbon steel, low alloy steel and heat resistant steel with proper welding wire. It is used for the welding of ships, boilers and pressure vessels.

Notes：
1.Re-dry the flux at 300-350℃ for 60 minutes before welding.
2.Remove rust, water scale, primer and other contaminants on the base metal before welding to obtain excellent weld deposit.
3.Add new flux regularly before using the recycled flux to prevent defective weld bead.
