Adaptors /converters big to little bottle

[pidgeon chit welder]

I have a pal up in East Anglia who has an industrial Co2 gas bottle connected to his DIY mig welder , 2 years ago when I was last there I noticed that he has some brass adaptors to enable him to run his welder off the big bottles.
Can any of you please point me in the right direction to locate such adaptors/ fittings .
I do not think he fabricated them himself .

Not sure from your post but if you mean he had a 'hobby' MIG connected to full size bottles (like BOC or AP type bottles), and you want to do the same then suggest you contact weldequip, a user on here. He should be able to fix you up.

Cheers

You can buy them readily off the shelf at any good welding supplier it has a push on type connector to go on the small pipe from memory.

Sounds like you're looking for something like this



Right hand connector goes to regulator and 4mm pipe from welder into left hand fitting.
