Hi
Mick
Pleased to see you are back on the job
Your alloy welding looks fine
A foot pedal makes a massive differance to the ease of welding

Nothing new to post I am afraid lads , as it looks like fault on the welder is causing the breaker to trip each time it turned on :zap: :bang: :bang: :bang:, so as usual one job leads to another job as the first job stands unfinished :palm: :palm:. My mate who knows about these matters is coming to test things on Saturday so fingers crossed its something fixable.
I noticed the welder let me down the instant I mentioned that Migatronic was good kit .................. Typical , I should have known better :(
Cheers Mick

Keep trying bigger circuit breakers - eventually the fault will reveal itself in the welder - just follow the smoke back to it's source :Doh: :doh: :doh: :Doh:
My professional welder mate uses Migatronic stuff pretty much exclusively, so it's obviously (normally) good stuff.

dont tell him to do that we did that at work ( Stanton Iron Works ) on the DC system it was a floating system with neither leg decked , we used two lamp in series with the centre point connected to earth to fault find earths ( a fault one the - to deck and one on the + to deck was a short ) but it could play tricks with the control ccts
the object of the post revolves around a stubborn earth fault we knew which breaker it was on 500a one so we strapped a large copper bar on a spare 1000a breaker to earth for the other leg , switched on a bit of a spark ( these were open switch gear ) the fault cleared ,
we when down stairs for a brew hey Jeff I can here a fire engine going up the road ( we had our own works Fire engine ) the oil store was in flames we found out later that it had DC lighting ccts so we did find the fault but burn down the oil stores about 500 gals of lub oil for the cranes and machine shop
so yes you may find the fault but it can backfire on you Take care with the sparky stuff it does not take prisoners if it get you hand to hand :zap:
