Type/characteristics:
Agglomerated fluoride-basic type flux for welding general structural steels pressure vessels, pipe steels, as well as fine grain structural steels. Owing to the manganese pick-up caused by AMA-OP120TT, low manganese wire electrodes will find an extended field of application. AMA-OP120TT is outstanding for tandem, multi-wire and twin-wire welding. It delivers a weld metal featuring excellent toughness properties and crack resistance.AMA-OP120TT can be used on either DC (positive) or AC up to approximately 1000A.Damp flux shall be redried by baking at 300°C-350°C

Grain size according to DIN 32 522:2-20

Main constituents:

CaF2	Al2O3 + MnO	CaO + MgO	SiO₂ + TiO₂
30%	20%	35%	15%

Basicity to boniszewskii: ~3.1

Metallurgical behavior: Pick-up and burn-off the alloying elements Si and Mn as a function of the alloy content of the wire electrode, DVS Merkblatt 0907, part 1
