Argon (Ar) — argon refill and cylinder exchange for welding

Argon is an inert gas used to shield the weld, giving a clean weld bead. It is ideal for stainless steel, aluminium and metals that require high-quality welds.

FAQ

Is argon flammable?

No — it is an inert gas and does not burn. But it is heavier than air and can accumulate in low or confined spaces, creating a risk of oxygen deficiency, so use it in a well-ventilated area.

What is the difference between pure argon and mixed gas?

TIG welding mainly uses pure argon, while MIG/MAG welding of steel usually uses an argon + CO₂ mix. See the mixed gases page for details.
