Hello Am wondering if any of the readers of this newsgroup have been following the efforts of several different people with regard to Home-Built TIG welding equipment and in particular the effort to attach a unit after the main transformer/rectifier of an existing TIG welder , I would be very interested hearing from anyone that has had success or failure with this process , Mr. Dave Barrett from B.C. has published a set of schematics for such a device at

, would be interested in hearing from someone that has built or experimented with this unit , I contacted Dave Barrett and he is too busy at this time to give much effort to the project , their must be a bunch of older welders out in the field that could be updated to modern standard , with the price of modern welders from $4,000 to $11,000 , I think it could be worth the effort , again , I would welcome all ideas . Thanks Phil L. W8KLK
