>>714725908not quite how mig switch works, mig switch on switch 1 (when done properly and you don't get banned immediately after the cartridge is loaded) is a one to one copy of the original cartridge, but there still has to be some kind of cartridge giveaway that switch 2 can pick up on
the armchair engineer in me is clueless, could be anything from a minute pressure difference in the cartridge loader to a real one or it just could be the switch 2's OS is a bit more foolproof
