I've seen something similar in Mig welders also.. although they are suppose to be constant voltage while TIG and stick is suppose to be constant current.
I have a Hobart Cyber-TIG also. It works but the current control pot on the front needs to be replaced as it is flaky. I have the single phase version and it is the most powerful single phase welder I have ever used. I've only used it for stick welding so far, but I have a tig torch setup for it also. They don't make them like that anymore! I have no idea if the meters on the unit even work as I really can't look at them while it is in use also.
