OP 190

OP 190 is an agglomerated aluminate-basic type flux for the welding of general structural steels, boiler and pipe steels, as well as fine-grain structural steels. To be used in combination with the wire electrodes OE-S2, OE-SD2 and OE-S2 Mo. OP 190 is suitable for twin-wire, tandem and multi-wire welding using the single layer or multi-layer techniques. For higher level of toughness, an OE-S2 Mo wire electrode is recommended when welding from both sides in one pass or when welding one-sided with the single layer technique. The finely rippled bead surface and the good slag detachability make OP 190 perfectly suited for fillet welds. It can be welded on DC and AC up to 1000 A with the single-wire technique.
