What is the size of the hose to the tig torch?

[amron]

Hi
I would like to know what is the size or how you define the prresure hose that has the power cord inside (the one that return the water from the torch). I have a problem with it and I have to make new one - I've searched and I cant
find the exact one, so I have to improvize and replace the original brass fitting from the new hose with the one that I had to disassemble from the original hose and know I have to find where I can swage it, so that's why I need to know the size of the hose.
Thanx for your help.
BTW - the welder is a Rilon wse315.

Hi Amron,

On my lead the flexable plastic pipe is 12.7 o/d x 8mm i/d. (1/2" x 5/16")

To crimp the copper braid I have a piece of bar in which I have drilled an 8mm hole, and then cut the bar so half a hole remains.
I place the current nipple in the half round slot and tap a groove in the copper to crimp the copper flex with a wide screw driver blade.

To crimp the plastic hose back on I use a "lemon clip".

'Current nipples' come in either 'machine end' or 'torch end' forms.

Hope this helps.
