SF-70W

FIller Metal Breakdown

SF-70W

SF-70W is the most widely used titania type flux cored wire for all position welding with CO2 shielding gas. Arc stability is excellent, so spatter loss is low and slag covering is uniform with good removability. SF-70W is effective for use in insufficient in insufficient ventilation and/or space areas.
