Application /
Properties:
Agglomerated
fluoride-basic type flux
for welding general
structural steels. As
regards silicon, AP125 produces a
slight pick-up. Where as
it is relatively neutral
as to manganese.
The weld profile is of smooth
and uniform.
AP125 can be used on
either. DC (positive) or
AC up to 1200 A on a
single wire.
Damp flux shall be
retried by baking at
300-350°C
Grain size in according
with DIN 32 522:3-18.
