Argon Regulator
This might be a dumb question!
I have been having much fun, ‘seriously’ with my group by TIG welder. Up to now I have been using argon shield gas from the MIG welder and gold tip
electrode at a bout 90 amps whilst modifying my pinto sump with half reasonable results.
Now I want to get some 'sexy' row of coins style welds so I need to use pure argon. I intend to start off using some disposable Clarke
bottles (110ltrs) before I shell out on a large bottle of pure argon
Question: - does anyone know where I can get a reasonably priced regulator for a disposable bottle with flow rate control?
Cheers in advance,
The Baron (with singed knuckles)

don't worry about it, if you are going to go to a proper bottle in the not too distant future then just set it by noise on the std little
regulator.
Retro RWD is the way forward...........automotive fabrication, car restoration, sheetmetal work, engine conversion
retro car restoration and tuning

for the amount of money you will spend on little bottles and a reg you could get a big bottle from Air Products with a built in regulator! You get a
specific flow regulator connection for your hose I went for 11 lpm and this is fine with a bit of tweaking on the torchvalve. If you are going to end
up doing a serious amount of welding i.e a locost worth just get a big bottle! I am on my third in two years having done the locost and a bit of other
welding including Land Rover bits and two sills on a Triumph Herald!

Machine mart cheapies can be very poor. I had to cut off the plastic bit with the scale to get it to work properly. That was the third one I had
from them, the forst two did nothing at all.

gas
The gas you want from B O C is called argonshield (light) and from air products is called (cougar). Hope this helps kev.

Argoshield and Coogar are mig gas, you need pure argon for tig. I don't understand how you have tig welded with Argoshield without burning your
tungsten away, it sounds like you have invented a new process

I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.
