Miller has a useful, short article on TIG brazing with silicon
bronze
up on their website:

It's worth knowing about.

I just tig brazed a cracked swivel base on an old athol vise that
was cracked badly
used alum bronze. Rod flows really well on cast iron
preheated and used a pretty long arc and a sharp tungsten
100 amps max with a pedal
AC with the ac balance maxed out.
Used alum cause Jody at welding tips said it shrinks less.
Did seem to pull quite a bit but short beads and cooled in a bucket
of sand overnite.

Hi Leon

Has anyone measured how hot they could preheat a chunk of cast iron on
a propane or charcoal barbecue?
