FLUX N 203

General description

Active flux for limited pass welding

Good general purpose flux, including semi-automatic

High speed on dirty plate

Good resistance to porosity on rust and primer

Good slag removal, good bead shape

Note: Use another flux for thick plates and multi-pass welding of thick plates (without particular caution) and for low quality steel
