Agglomerated alloy-bearing type flux for hard surfacing purposes, to be used in combination with 50-11 wire electrode. 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/50cm/min. AMA OP 250 A is suitable to be used on either DC or AC.
