Yes you can buy one. ££££££ Click here

I wanted nitrogen, but the cost for what I wanted it for made it too much for the project

For the argon, look up you neares 'Hobbyweld' dealer...
https://www.hobbyweld.co.uk/products/argon/

Plasma, A far as i'm concerned, theres only one name in Plasma cutting, Hypertherm. Top notch gear, using it at a professional level, i dont have room for any inferior machines.
Not very helpful for a DIY forum I know, but i just dont have any experience of lesser machines..... but is a plasma cutter really what you need? As in the other thread- Retired mentioned a plasma many times, but discovered a bandsaw was a better investment...

What sort of stuff do you plan on cutting/making?

Sounds like you are heading along the right path then. :thumbleft:

I keep linking back to http://www.mig-welding.co.uk/tig-tutorial.htm for welding related tips and such.
Might be worth looking on the forum section regarding the plasma too, fair few of the guys there have budget cutters.

The tutorial was created with the assistance of a dceent time served Tig welder.
The biggest tip I can give you is make sure you are resting your hands steady and practice welding with the torch and rod before you press the button on the torch- easier to see where you are going wrong when everything is daylight and you havnt got a head shield on.
Just practice moving the torch along without touching the tungsten, then start pretending to add rod without touching the tungsten or taking it too far away.
Youll save yourself a fair bit of gas and consumables if you master that.... when you actually go for it, it will feel different, but youll be half way there.
