I am getting ready to buy a millermatic 252 with spool gun. I currently have a 110 miller mig and a tig welder. I have 2 bottles, argon and 75/25 and dont want to buy 2 more bottles to put on the 252 cart so I am looking for a quick disconnect system that would attach on the back of the machine and allow me to quickly swap machines.

any ideas?

 

Might check at a local welding supply shop and see what they recommend. Or I would think a regular compressed air disconnect would work there, low pressure after the regulator. Type I or Type T chucks would probably be easy to find:

 

I've been using push-in fittings for years, never had a problem. 1/4" OD clear beverage hose is only 20 cents per foot.

the fitting itself is about $3-5 depends where you buy them. this one in the picture is brass, but, I've used white plastic ones, they are just as good.

 

This is what I do because I have several welding machines set up at different parts of my lawn shed it works for me.

I have a normal every day cylinder cart most often seen in use with a oxy- fuel set up one cylinder 75/25 one pure Argon. 2 flow meters 2 hoses easy to move quick to change cylinders

All I need is a 11/16 wrench which stays in the tray on the cart

This was just one of those pure chance things that worked well because I had the cart and it was just sitting there .

 

so can someone link me to the quick change fittings on a site?

thanks for the help

 

 

i have been but cant really find argon specific ones.

 

any other ideas?

 

I did see a manifold set up a while back that used quick disconnect fittings if I recall the fittings were very expensive$$$

I looked into doing it . they might have come down in price but till i priced out the fittings I needed it would have paid for a few cylinder fills so I gave up on the idea.

Like said check with your local supplier

** I just looked Air Gas has them in the Catalog to fit B style Flowmeters they are color coded Blue for inert gas

 

yeah i looked at the oxy/acet setups and they are like 30$ per pair. wondering if air hose disconnects would work like roger mentioned...

 

They should work for you but I would get the twist lock kind so you don`t uncouple them by mistake.

Air is cheap compared to inert gas so you want to keep your hose as short as possible .That you are plugging into the female connector to keep your inert gas loss as little as possible

I would for sure break out the soap bubbles to be checking for leaks.

 

yeah, I was going to look up molecule size of air vs argon to see what kind of differences the seals might make also...
