0445013881 - ESAB Nozzle Gas Flow Tester / Peashooter

Precise Verification of Shielding Gas Flow

The ESAB Gas Flow Meter (SKU: 0445013881) is an essential diagnostic tool for any welding operation prioritizing quality control and efficiency. In complex welding setups, the flow rate indicated on the cylinder regulator or flowmeter does not always correspond to the actual volume of gas exiting the torch nozzle. Discrepancies can arise due to backpressure in long cable assemblies, micro-leaks in hose connections, or restrictions within the torch liner itself. This handheld device, often referred to as a 'peashooter,' provides a definitive measurement of the gas flow actually reaching the weld zone.

Designed for versatility, the ESAB flow meter is compatible with all standard shielding gases, including Argon, Carbon Dioxide, and Helium blends. It features a graduated scale that allows operators to read flow rates in Liters Per Minute (LPM) or Cubic Feet Per Hour (CFH), depending on the specific model calibration. By placing the rubberized intake over the gas nozzle of a MIG gun or TIG torch, the device utilizes a ball-float mechanism to indicate the precise flow rate. This immediate feedback allows for the calibration of power source solenoids and cylinder regulators to ensure they match the required Welding Procedure Specifications (WPS).

For industrial environments adhering to ISO standards, verifying gas flow at the nozzle is a critical step in equipment validation. Insufficient flow leads to porosity and oxidation, while excessive flow creates turbulence that pulls atmospheric air into the arc. The ESAB Gas Flow Meter eliminates the guesswork, ensuring that the shielding gas envelope is stable and laminar. Its durable composite construction ensures it can withstand the rigors of the shop floor, making it a mandatory addition to the toolkit of welding engineers, inspectors, and maintenance personnel.
