Ideal Gas Pressure For Mig Welding. For most pressure regulators for welding process the outlet pressure is set in psi or in some cases in bar or kPa is regulated from a minimum of 25 psi 17 bar 170 kPa to 80 psi 55 bar 550 kPa. Another thing to watch for is not to have the gas setting to high.

MIG Welding Gas Pressure For most gas regulators the gas pressure PSI from your gas flow regulator or pipeline is set at a minimum of 25 PSI and as high as 80 PSI. Helium He can be added to increase penetration and fluidity of the weld pool. The gas pressure in the hose going into a wire feederwelder while welding typically varies from 3 to 8 psi.

Argon is heavier than air so whatever gas is released in welding stays in the atmosphere to be recaptured again and again.

Regulators designed for CO2 generally range from 50 to 80 PSI. The normal gas for TIG welding is argon Ar. Welds made with argon shielding gas will be smooth and attractive with no slag or oxidation visible. Regulators designed for CO2 generally range from 50 to 80 PSI.
