Type/ Characteristics: Agglomerated alloy-bearing type flux for hard surfacing purposes, to be used in combination with 50-11, 50-22  wire electrodes. The alloying effect of the flux depends to a large degree on the welding parameters chosen. Optimum parameters for a 4 mm dia. wire electrode are 600A / 32V / 50 cm/min. welding speed. AMA OP 350 A is suitable to be used on either DC or AC. Damp flux shall be redried by baking at +300 ˚C
