I know some people who will not allow flux in their
houses and others who would solder nothing without flux.
I have read tutorials about soldering and the use of
flux is either encouraged or not.
I have used Tix Flux for years with no apparent
problems, on track and electronic items, like decoders.
So I am turning to this group for some reasoned
arguments for or against the use of flux.
What has experience taught you and what has your own
research taught?
