Type and Characteristics:<\/strong><\/p>\n\n\n\n

Agglomerated Manganese-Silicate type flux for high-speed welding. It is preferably used for welding thin plates at speeds higher than 2.5 meter\/min. Welding properties arc outstanding on either AC or DC up to 800A.
AMA OP155 is Suitable for Welding tube-web-tube joints on finned tubes. Exhibiting slag removal.
It is likewise suited for tandem and multi-wire welding.
AMA OP155 produce high Manganese pick-up which decreases with increasing Manganese content of the wire electrode.<\/p>\n\n\n\n
