OVERVIEW

Technical Verification for MIG and TIG Processes

The ESAB® (Oxweld®) Gas Meter (SKU: 19043) is a precision instrument designed for the secondary verification of shielding gas flow rates in industrial welding environments. While cylinder regulators and flowmeters provide a reading of gas leaving the supply source, they cannot account for pressure drops (delta P) occurring throughout the gas delivery system. Restrictions in the gas hose, clogged solenoid valves, damaged liners, or spatter-filled gas diffusers can significantly reduce the volume of gas that actually reaches the weld zone. This portable flow checker bridges that gap by measuring the output at the point of use.

Engineered for durability and accuracy, this device features a clear, impact-resistant tube with distinct markings calibrated in Cubic Feet per Hour (CFH). It utilizes the variable area (rotameter) principle, where a ball float rises within a tapered tube in proportion to the gas velocity. The unit is equipped with a flexible, conical elastomer boot designed to create a gas-tight seal against standard MIG gun nozzles and TIG torch gas cups. This ensures that the reading reflects the total gas volume exiting the torch.

This tool is manufactured in the United States under the reputable Oxweld® trade name, ensuring compliance with industrial standards. It is compatible with all standard shielding gases, including pure Argon, Helium, Carbon Dioxide, and tri-mix blends. For welding engineers and QA/QC inspectors, this flow meter is a critical component of a robust welding procedure specification (WPS) adherence program, allowing for the validation of parameters on the shop floor. It effectively isolates equipment malfunctions from operator error when diagnosing shielding issues.

FAQ

Hold the meter vertically and press the rubber conical end firmly over your MIG nozzle or TIG cup. Trigger the gas flow (without striking an arc) and read the value where the ball hovers.

This device measures gas flow rate, specifically in Cubic Feet per Hour (CFH), not pressure (PSI).

Yes, the meter is suitable for measuring flow rates of Argon, CO2, Helium, and mixed shielding gases commonly used in welding.

A lower reading at the nozzle usually indicates a restriction in your system, such as a leak in the hose, a clogged diffuser, or a kinked cable. This tool helps you identify those losses.

No, it is a mechanical flow meter that uses the physics of gas flow to lift a ball in a tube; no power source is needed.

Yes, the flexible rubber boot is designed to fit over the end of almost any standard MIG nozzle or TIG cup regardless of the torch brand.

The scale is marked in Cubic Feet per Hour (CFH), which is the standard unit for shielding gas flow in the United States.

No, you should only use this to test gas flow before you start welding. Do not attempt to strike an arc while the meter is attached to the torch.
