So I recently bought a haas induction shrink fitter machine for my shop.
I didn't do my homework until it arrived and was surprised to realize it needed 220v 3ph. I realize that shouldn't be surprising.
I do have an RPC in my shop, BUT right now it's directly wired into my VF2, and it will be a logistical nightmare to add a subpanel just because of space constraints on the wall, I can do it if I have to.
BUT, right where I want to put the machine I have a 30 amp 220v 1ph plug on a dedicated 30A circuit. I was thinking I could put a VFD on that circuit to run the heat shrink machine.
Now, the shrink fitter says it will pull 30A 3ph, so that's significantly more than the circuit is rated for, BUT the maximum run time of the shrink fitter is 9 seconds, most of my tooling will require a 5 second heating cycle. I suspect it won't trip the breaker in that amount of time. Is it totally insane to think I can do this with the VFD?
Or should I just suck it up and do a multi-thousand dollar subpanel for the RPC and be done with it.
