Welding Gas — now purchasable on Amazon (correction)

Filled 100% Argon and 75/25 Argon/CO2 cylinders (40/80/125 CF) are currently sold directly on Amazon (e.g., PrimeWeld-brand tanks) with HazMat-compliant shipping to the lower 48 — the source video's "can't buy gas on Amazon" claim is outdated.

Buying locally from a welding supply shop is still often the better move in practice — face-to-face fill/exchange service, and you avoid one-way HazMat shipping costs on a heavy pressurized cylinder. Starting with 100% Argon for versatility across TIG on steel, stainless, and aluminum is accurate, standard guidance.
