Thanks for all your replies and infomation fella's.

Like I said I only used to use a VERY OLD 3 phase thing that stood about 4' high, and was about 2' wide, had a lot of things on the front you used to push or pull to change power, and that was all trail and error as nothing was marked. I was just after something to do a bit of the odd welding around the place and I was told not to get a small welder as they have problems getting the amp or voltage up high enough to start cleanly and often they stick. And of course, it is cheap enough!

Thanks to all
