up the purge gas flow? Do you use a dual flowmeter, with one line going
to the TIG torch and the other feeding the purge? Or do you run the
purge from a "Y" off the main feed to the torch (with the "Y" hooked up
after the gas flow solenoid)?
The former method has the advantage of being able to regulate the CFH
of the torch and purge feeds separately. However, if you forget to shut
off the purge when you're done welding, you'll use up a tank of gas
pretty quickly. Or is this something you don't forget after you've done
it once or twice!
The latter set up forces the purge feed to run at the same CFH as the
torch, but the purge will stop and start automatically with the torch
Suggestions welcome - thanks.
