Problem with Tig Welder

[McD]

I am an electrician working on an offshore project in Australia and the welders are using Maxstar 200 to Tig weld pipes together and today one of the guys tells me it would work and then stop on and off a few time and now wont work at all. The power is on and correct voltage, the display is on and set correctly to tig weld, I can hear the inverter squealing and when i press the button for the HF start it sqeaks a bit louder for a second and then nothing, no arc will strike and no gas flow, there is no fault codes coming up on the display only the amperage it is set to which doesn't change. I have removed the lid and all looks good and smells ok. I really dont know what else to look at ? It wont scratch start either, just seems like there is no output what so ever please help. Steve

check the cables in the torch back to the machine

as you will have seen invertors are very complex compared to the transforemr types
some one may come along with suggestions

As a electrical engineer myself Miller welders seem to be the best to work on?
