Argon ArSupplier & Manufacturer in India

Welding-grade argon shielding gas for TIG / MIG.

Formula: ArPurity: 99.99%+Appearance: Colourless, odourless, inert
Ar

Inert argon shielding gas for TIG and MIG welding, metal production and high-temperature processes — pure and in tailored mixtures.

Argon (Ar) is a noble, completely inert gas separated from air during cryogenic distillation. Its inertness and density make it the standard shielding gas for arc welding, where it protects the molten weld pool from atmospheric oxygen and nitrogen to produce clean, strong, spatter-free joints.

IIGAS supplies welding-grade and pure argon in high-pressure cylinders, cylinder banks and as liquid argon, along with argon-CO₂ and argon-helium mixtures tuned for specific metals and deposition rates. Beyond welding, argon is used for steel degassing, heat-treatment and sintering atmospheres, crystal growth, and as a fill and carrier gas in analytical instruments and lighting.

Frequently asked questions

Argon is the standard shielding gas for TIG and MIG welding, plus steel degassing, heat-treatment and sintering atmospheres, crystal growth, and analytical instruments and lighting.
Welding-grade argon (99.99%+) suits most TIG/MIG work; argon-CO₂ and argon-helium mixtures are available for specific metals and deposition rates.
Argon is completely inert and denser than air, so it blankets the molten weld pool and protects it from atmospheric contamination, giving cleaner, stronger welds.
Yes — Ar-CO₂ and Ar-He blends prepared to specification for welding and other applications.
Yes, liquid argon is available for high-volume users alongside cylinders and cylinder banks.
Argon is separated from air during cryogenic distillation in air-separation units.
Welding and pure grades at 99.99% and above, with higher purities for specialised use.
Argon is inert and non-toxic but can displace oxygen in confined spaces; ensure good ventilation.
47 L cylinders at 150–200 bar, cylinder banks and bulk liquid argon.
