Curious, with the Prime Weld Cut60, do you really ever use it in the 110v setting? Looking at the cut chart not much you can cut with it? Am I wrong?
Regardless of the plasma cutter used, running it at 110v not only reduces capacity, but also duty cycle.
Run it on 220v.

It’s true halving the volts halves the (wattage) capacity which halves the amperage once it’s DC but the one thing it doesn’t affect is the duty cycle which stays constant whether using 220 or 110.
The duty cycle is a percentage relative to the amperage being used at the time.
@Terryg Use 220v if you have it available like @Kwikfab said.
I have a Miller passport plus which runs on 220 or 110 with a external or internal cylinder. It’s super handy if I have to climb up on a roof and make a little repair. But it’s always nice to have all the amps you can have.

I guess I’m being kind of semantical.
110 or 220 effects which duty cycle range you would choose from.
Compare one range to the other versus amperage it would be half.
But if you compared the entire range to each other it would be equivalent.
Can’t run both ranges at the same time.
Electrical always adding up somehow…
I think you’re missing some perspective. For Primeweld Cut 60, the maximum current you can get running at 110V is 30A output. At 30A output, 110V supply, you are limited to 60% duty cycle. Cutting the same material (using 30A of course) with 220V supply you have 100% duty cycle. It’s all about what you’re cutting and the current it needs to cut. I’d say probably in most cases, if the PC is duty cycle limited at 110V, it will NOT be limited with 220V input at the same output current.
With my PC, the max current with 110V input is 35A, but the PC will run at 100% duty cycle at this current, whether it’s 110V input or 220V input. It’s limited to 60% duty cycle at 55A output but I can’t possibly get 55A output with 110V supply.

Overthinking it.
I am saying your Duty cycle is relative to the amount of available power.
it’s like a gas gauge in a car can be full or empty or somewhere in between .
the gauge is relative to amount of fuel left not the quantity of fuel left.
1/2 full is 1/2 full regardless if it is a 20 gallon tank or a 35 gallon tank.
It’s not recommended, regardless. Call an electrician or upgrade your shop power yourself to get the required 240 volts. You will thank me later.
