The On-Torch Air Flow Tester is a simple but essential tool for welders using TIG or MIG torches. Instead of relying solely on regulator-mounted gauges, this tester lets you measure actual gas or air flow right at the torch nozzle — where it matters. That means you can quickly confirm that your shielding gas (argon, CO₂, or mixed) or air supply is reaching the weld zone at the correct flow rate, avoiding gas starvation or wasted gas.
Whether you are setting up a new welding station, switching torches, or simply performing maintenance, this flow tester gives peace of mind that you’re welding under optimal gas/air conditions.
Key Features
Torch-End Flow Verification: Measures shielding-gas (or air) flow at the actual torch tip - not just at the regulator — ensuring accurate flow right where it matters.
Simple “Peashooter” Design: Slide the tester over your MIG or TIG torch nozzle, open gas flow, and read the ball indicator in the transparent tube - no complex setup required.
Works with Common Welding Gases: Compatible with argon, CO₂, and common argon/CO₂ mixes — suitable for most MIG and TIG welding applications.
Helps Avoid Porosity & Gas-Related Weld Defects: Ensures you have adequate shielding gas coverage to protect weld pool from atmospheric contamination, reducing risk of porosity, oxidation, or weld-quality issues.
Quick, Portable & Easy to Use: Lightweight and easy to carry, ideal for workshop use or on-site weld checks — useful for setup, maintenance, or periodic verification.
