Hello everyone,
I was wondering if anyone could throw some light on an issue I've been having. At work I am the custodian and user of a Miller Diversion 165 TIG welder. It is mainly used on aluminium, and occasionally stainless.
It hasn't exactly got what might be termed "bells and whistles", however I have done some excellent work with it, if I do say so myself! It has been the mainstay of many of my work repair projects.
It has developed a niggling problem, however. Very often when attempting to start the arc, the HF does not kick in. On pressing the torch button, the blue LED indication for HF illuminates, but there is no audible indication that the HF is on (as is usual on this and other machines I've used), and the arc won't start. If I scratch start the arc then all is well and I can continue welding. As you can imagine though, scratch starting on aluminium and stainless is not exactly ideal.
I suspect that the HF board is the cause of the issue. I have the manual for this machine and it gives fairly comprehensive circuit diagrams and testing information, so I think I can diagnose the problem given time. I am just wondering if anyone here has witnessed anything similar with these (or any other) machines and what the cause was? I'm trying to see if I've missed something very obvious before I get more invasive.
Thanks,
Carl.
