Can I use ANY MIG welder with gasless mode, aka. Flux core? (sopuli.xyz)

I'm a total newbie, and I want to buy a cheap-ish welder that can do MIG and Flux Core (apparently this is gasless MIG), in case I want to opt into trying out in the future.

The big difference between a mig welder and a flux core only welder is the control hardware for the gas solenoid. The mig machine will have it and the flux only machine will not.

There might be a difference between the guns, but that is mostly the gas nozzle in the gun. You need it for GMAW but not for FCAW.

Upgrading from a FCAW only welder to GMAW will require buying a new welder. Modifying a FCAW only welder wouldn't be worth the effort.

If money is the issue, it was for me when I got my first welder, check out the welders offered on Amazon. Some of those are surprisingly good quality.
