in this video, you will see a 3g test plate welded with short circuit mig . AWS terminology calls this process gas metal arc welding - short circuit (GMAW-S)
I still call it short circuit mig.
I used .035" er70s6 wire and C25 gas (75 argon/25 co2)
The plates are A36 steel 3/8" thick with a 30 degree bevel.
gap was 5/32" with no land
Settings for root were 17 volts and 180 ipm on wire speed
second pass settings were 18 volts 210 ipm
cover pass settings were 17.7 volts 200 ipm
I also did a quick cut and etch macro test at the end to verify fusion between each pass.
