OP 191

OP 191 is an agglomerated rutile type flux for welding general structural steels. It is also used for welding fine-grain steels with a yield strength of up to 355 MPa. Relatively high silicon pick-up is achieved with this flux and when used in conjunction with OE-S1, OE-S2 wire electrodes manganese pick-up also results. OP 191 is particularly well-suited to twin-wire, tandem and multi-wire welding at high speeds. It can also be used with the two-run technique especially when weld thin-walled spiral tubes. The good slag detachability makes OP 191 a standard for fillet welding. OP 191 can be welded on DC+ or AC at up to 1500 A.
