Ok, oddball question.
I have a need to use a very large welding power supply for creating a stable arc. The arc is created in an inert atmosphere between a water cooled piece of copper and a tungsten electrode and the radiant heat melts samples such as platinum or rhodium. Thus far, I have been using my TIG welder, but I'd like more power...I'm at 300 A right now.
I can pick up 650 A power supplies pretty cheap, but they are constant voltage...I've always had a rudimentary understanding that CV was for wire feed and CC was for TIG or Arc welding and that fundamentally it's transformer design that sets them apart. BUT...I have no understanding of whether or not a CV power supply will be able to maintain a stable arc for a relatively short period of time.
In this application, the arc is started with a high frequency arc starter and then the arc length is kept relatively constant.
Is anyone able to explain what the difference would be between my current, CC power supply, and a CV power supply.
I just need power...and lots of it.
