Not sure if it's in my head, but I seem to get cleaner welds and less spatter from inverter mig.
They even weld nice and clean on pure co2, I'm currently using argoshield but it doesn't seem any better whereas transformer migs seem to weld cleaner with argon in the mix.
You don't have the huge inrush current needed to saturate the transformer core with electromagnetics either so they're easier to run off generator or inverter.
