I have an odd job at work that needs a BIG powersupply to run a small furnace - ideally I want to be able to dump 8 Kilowatts into a resistor, and let it get hot. Very, very hot. 2500F hot.
Now our existing system uses a 1500 USD transformer to do that, but I acquired an Inverter TIG a few months ago, which is almost the same output power, weighs next to nothing and cost damn all (by comparison to a transformer, power control electronics, circuit breakers etc in the current system). The saving in shipping costs for the final rig is worth considering too !
Is using a TIG supply a really stupid idea ? 30 volts is a typical on-load output voltage, at up to 150 Amps, at 100% duty cycle, which is just enough. Are there any obvious gotchas ?
Thanks for your input
