my local welding supply company have just started stocking GYS gear. the 3 phase synergic migs and 200 amp AC/DC tigs have got me very interested mainly because of the price.
i have an 180amp gys ac/dc tig that i have been using for the past couple of years and it works quite well and has certainly paid for itself, i would recommend one based on price and its capabilities its not a top end machine but it has done all the work i have ever needed to do.
