Flux for Submerged Arc welding of General Struct

AMA OP250A

Standards: EN 760: S A CS 3 97 AC
DIN 32 522 B CS 3 97 CCrMo AC8

Type/ Characteristics:

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.
