          Lower voltage to 18V on your Miller Multimatic 220 AC DC, use 20 CFH argon, reduces flicker.

            Check mig wire quality on your Miller Multimatic 220 AC DC, bad wire causes flicker, use 230 ipm.

              Clean liner with alchohol on your Miller Multimatic 220 AC DC, dirty liners cause flicker, check contact tip.
