I want to be able to internally purge stainless pipe fabrications, but
can't justify hiring two full size bottles. Can you buy an adaptor to
run two regulators off one full size Argon mix bottle? One to run the
TIG and one with desperate pressure control, to purge the fabrication? I
am in the UK if anyone knows who sells such a thing. Thanks.

You should be able to make your own manifold. The standard configuration
for Argon regulators in the US is a CGA580 to 1/4" NPT pigtail coming
into the regulator. A good welding equipment supplier will have 1/4" NPT
T's, elbows, and nipples. Unscrew the CGA580 pigtail from your regulator
and screw it into the T. A pair of 1/4" NPT close nipples to a pair of
elbows followed by a pair of 1/4" NPT long nipples to the regulators and
you are good to go. Use pipe dope or teflon tape during assembly and
leak test with soapy water when done.
If your gas supplier does not have these parts, Swagelock or
Parker Hanifin (sp?) will have them in brass or stainless. I would use
brass, assuming that your regulator bodies are brass.

tank pressure. Go to McMaster-Carr for properly rated hardware.

Rather than mess with dual regulators, the normal way this is done is
with a single regulator and dual flow meters with control valves.
Cheaper and safer.

This seems to be the accepted method. at least when I asked my welding
supply about purging they immediately fished out the fittings to adapt
two flow meters/valves to the regulator.
