FAQs About Welding Gas Regulators
What is the use of a regulator in gas welding?
A regulator controls the pressure of gases coming from the cylinder to make welding safe and stable. It reduces high cylinder pressure to a usable working level for the torch. This ensures steady gas flow, clean welds, and prevents dangerous surges. Without a regulator, gas flow would be hard to control.
What type of regulator for TIG welding?
For TIG welding, you need an argon or argon/CO₂ regulator designed for shielding gas. These regulators typically come with a flowmeter to set the gas flow in cubic feet per hour (CFH) or liters per minute (L/min). A single-stage regulator is fine for most TIG work, while a dual-stage regulator gives more consistent flow. Always match the regulator to your gas type and cylinder fitting.

Do you need a regulator for TIG welding?
Yes, a regulator is essential for TIG welding. It keeps the shielding gas flow steady, which protects the weld pool from contamination. Without a regulator, you can’t control the gas pressure or flow properly. This can lead to poor weld quality, porosity, and wasted gas.
What psi should my welding gas be?
For TIG welding, the cylinder pressure can be over 2000 psi when full, but the regulator lowers it to a safe working range. Most TIG welding runs with a flow of 10–20 CFH (about 7–14 psi depending on your regulator and setup). Thin materials may need less gas, while outside or drafty areas may need more. Always adjust flow by the flowmeter, not cylinder pressure alone.
