Page 24: Shielding Gas Recommendation
The general rule to be followed for shielding gas flow rate is 10 to 12 times of the wire size. It may increase for different welding applications where higher stick out and parameters are used. When using helium mixtures, the flow rate must be 1.5 to 3 times more than with argon. 0463 730 001 - 24 - © ESAB AB 2021... -
