It looks OK, but just be aware that it should not run off a 13A socket.

As far as gas is concerned, get a cylinder, the disposables will cost a fortune and only last about 20 minutes (if you are lucky). There are two options Rent or Buy, Renting will cost you more and if you buy you can go pub gas or argon welding mix. Pub gas (Carbon dioxide) is cheaper but the proper weld mix gives better results https://www.hobbyweld.co.uk is a good place to look. Don't forget you will also need a regulator and flow meter.

I would also recommend an auto-darkening mask.
