Argon gas plays a vital role in TIG welding, offering clean and stable welds. It protects the weld area from contamination and ensures high-quality results.
TIG welding requires an inert gas to shield the weld pool from oxygen and moisture. Argon, being a noble gas, provides excellent protection without reacting with the metal. Different sizes of argon tanks, like 40, 60, 80, and 125 cubic feet, suit various welding needs.
Tanks come with CGA 580 valves for secure connections. Regulators and flowmeters help control gas flow for consistent welding performance. Some mixtures include 75% argon with 25% CO2, mainly for MIG welding. Pure argon, however, remains the best choice for TIG welding. Using the right argon gas and equipment improves weld strength and appearance.
