Hi, I have an SIP MIG welder and have been happy with it. However recently I attended a course and discovered the great finish that can be had with a TIG machine. So I am considering getting one. I am hobbyist only (Although if I become good at it I could consider car bodywork). No expertise at all, so would be interested in getting the most inexpensive one that is straightforward to learn with. Has anybody any experience and if so could you advise? Thanks.
