this gas mix will be axial spray which is more penetration . if u face this issue only with some welders and others is OK , this may related to more welders training is needed . U can cut macro from one good welder and one u r doubted " using same parameters " then compare

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,
