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.
