Hello I have a one of these units with the WU-10 water cooler. There is virtually no parts or support for these machines in America so I figure I would ask this great site. My water cooler is not staying on when powered up. It will sometimes stay on for a few minutes but then it shuts down. Even if you hold the button in it will not allow you to weld. The welder will stick fine but no Tig which I believe is solely caused by the water cooler. I have disconnected the lines and the pump is pumping coolant. I have taken the cooler apart and nothing looks burnt or fouled up. This machine is a tranformer type probably from the early to mid 90's. From the little tech support I have gotten in America it is probably the pressure of the pump being to low or the circuit board is bad or part of it damaged. Well any help would be tremendously appreciated and I thank all ahead of time.
