Not long ago I dug out my old Gysmi HF130 inverter which went pop many years ago - but the MMA side of things was still functioning fine so have been using it for that purpose until yesterday evening...
I as welding up some simple brackets using 2mm rods (50amps or so on the dial) and upon finishing and lifting the welder out of the way whilst still switched on there was a feint click and the welder shuts off - I swear I saw out of the corner of my eye a small arc jump from the case of the welder to a plastic barrel of hydraulic oil as I lifted it up???. Whatever happened it tripped both the 16amp breaker for the ring main and also the main 42amp breaker for the circuit board. Upon resetting the breakers the welder now seems dead - the main switch lights up but the cooling fan doesn't fire up nor is there any power to weld.
I opened the case to have a quick look and can't immediately see anything majorly wrong, plugging it in and turning it on results in what looks like a relay constantly clicking and a white ceramic looking component next to it gets very hot within 10 seconds or so and has a scorch mark on its side:
It's definitely not worth sending it off to be looked at as now I have an oil cooled arc welder it's largely redundant (though still handy for jobs out and about and the odd scratch start tig job) but being fairly handy with a soldering iron but not so good at electronic circuitry is there anything worth me checking / replacing before chucking it completely?
Any advice appreciated...

. Thanks for the offer - If I get any advice with what to test I'll get in touch for some reference voltages etc.
