Mig Welding Aluminum

I have a Miller 3035 Spoolmate and was wondering if anyone has any Voltage and wire speed settings that would work for a test plate.The test is a 3/8'' plate with 30 degree bevel on one and a flat edge on other 1/2'' gap with 1/4'' backing bar.I am using .030 4043 wire.Thanks Dave.


probably 21-22 volts but wire feed will be over 400 ipm with that small .030 wire.
