Cobel 200 TIG gas inlet

[Neil.]

Hi guys.
Just a quick one. Anyone know what the gas inlet size is on this machine?

Yes I know I've just bought a Sherman, but at 200 quid, it would have been rude not to....

Does it say in the instructions?
Otherwise measure it and somebody can make a guess.
I guess 3/8" but no idea from looking at a photo really

Just whipped one up on the lathe.

Ta anyway.
