Uses |
| |
Argon (Ar) |
Inert |
Welding virtually all metals except steel |
| |
Helium (He) |
Inert |
Al & Cu alloys four greater heat and to minimize porosity |
| |
Ar & He (30-80 to 50-50%) |
Inert |
Al & Cu alloys for greater heat and to minimize porosity, but with quieter, more readily controlled arc action |
| |
Nitrogen (N2) |
Reducing |
On Cu, very powerful arc |
| |
Ar + 25-30% N2 |
Reducing |
On Cu, powerful but smoother operating more readily controlled arc than with N2 |
| |
Ar + 1-2% O2 |
Oxidation |
SS & alloy steels, also for some deoxidized copper alloys |
| |
Ar + 3-4% O2 |
Oxidation |
Plain carbon, alloy & ss (generally requires highly deoxidized wire) |
| |
Ar + 20-30% O2 |
Oxidation |
Various Steels, mainly with short-circuiting arc |
| |
Ar +5% O2 + 15% CO2 |
Oxidation |
Various steels using deoxidized wire |
| |
Co2 |
Oxidation |
Plain-carbon & low alloy steels, deoxidized wire is essential |
| |
Co2 + 3-10% O2 |
Oxidation |
Various Steels using deoxidized wire |
| |
Co2 + 20% O2 |
