Regular-20:

REGULAR-20 is a heavy coated electrode designed for flat and horizontal fillet welding of mild steel where high strength and radiographic quality weld deposits are required. Characterised by deeply penetrating, forceful, spray type arc with easily removable slag. The electrode can be used by with high current and high speed of travel to get economical welding.
