What does 'multiprocess' mean on these welders?

Multiprocess machines combine MIG (solid wire with gas), flux-core MIG (gasless), stick/MMA, and lift-start or HF TIG in one unit, and some add a spool gun for aluminum or even a plasma cutter. It lets one machine cover most jobs, though dedicated single-process welders can still outperform an all-in-one on any given process.
