OP 143

OP 143 is an agglomerated calcium-silicate type flux for welding general structural steels, boiler and pipe steels. The welding flux produces a high silicon and manganese pick-up when using wire electrodes OE-S1, OE-S2. OP 143 is particularly suited for twin-wire and multi-wire welding at higher speeds and for welding from both sides in one pass. For enhanced weld metal toughness OE-S2Mo should be used. The high current carrying capacity up to 1200A single wire technique makes OP 143 the ideal flux for all applications where high currents are involved for example multiwire welding or surfacing. Easy slag removal in all cases. The slag freezes quickly and allows circumferential welding of small-diameter work pieces without the slag running off.
