[MW:32196] GMAW change gas from 100 %CO to Ar+5%O2

Dear all,
I faced a problem with penetration in fillet welds when decide to change the gas type, as mentioned.
Most welders are doing well with this change, but some make loser penetration.
Details: mild steel, 2F welding position, wire feed speed 450ipm (optimized), 10˚ push angle, 

What could be the reason?  

Thanks,
