Thanks very much for the reply, I really appreciate the info.
TBH I`m not looking to weld ally with it, just mild and stainless.
I`ve used a Mig before for stainless, but I wasn`t really impressed with the weld quality, so wanted to go the Tig route instead. Plus the chances of blowing through thin section mild steel, seems to be a lot less with Tig.
The Tig welder I used before was a full blown industrial model, with all the bells and whistles, and cost about 3 grand

. But I definately don`t want to spend that much

.
Thanks again for your help, I will have a look through the links later. I only have single phase power in my unit, so I won`t be doing any arc welding. Will have to keep an eye out for smoking plug sockets though...LOL...
Regards,
Ian.
