Help with gas flow settings

What are the gas flow parameters for 90/10 argon/co2 mix in GMAW. Using .052 @ upto 29 volts and 450 WFS ?????


---------------------------------------------------

nozzle size is a big factor. and that is a pretty big puddle with high current and speed rates.

try around 30-35 cfh.

to save gas, you can gradually adjust lower until you get problems like porosity.

then increase by about 5 cfh to be safe.
