I am thinking about getting a TIG welder and need some advice.

The frame I will be building is 5mm thick section, so the first question is - What power welder do I need ?

Is this one suitable ? It is in my price range http://welduk.com/product/sip-05266-...-torch-160-amp AND WeldUK deal with welding equipment and not much else. I have bought from them before and I trust them. I say this because the cheaper 200A welders on eBay all seem to be sold by businesses that sell all sorts of fancy goods and have low feedback scores.

What does the team think ?
