G'Day Guy's,
Well with toriods getting harder to find there a heap of old non working 3 phase welders here at work so I'm thinking of stripping one down for a look and the best part plenty of that 6x5mm or even bigger copper wire for making shunts is there for the taking. Now these 3 phase welders have 3 big transformers so by ganging up all 3 and winding a new secondary would make one think of it would be a pretty heavyduty transformer.
I will have to get motivated and wind up a secondary for that E-core I got out of that forklift battery charger and give it go with this inverter build.
Also I do have that toriod out of the Kipoint inverter which is rated at 3Kw with a 8Kw surge, as it's already wound for 24 volts it should be a drop in replacement.
But I like to think something can be done with these old 3 phase welders I now have access too.
Cheers Bryan
