Type: differential pressure flowmeter Measuring range: 0-25L/min (m3/h) Accuracy class: 4 Nominal diameter: 8 (mm) Applicable medium: argon, AR CO2, etc Working pressure: 0.35 (MPa) Working temperature: 25 () Specifications: 1 Usage: 1. Put the gas flow meter at the nozzle of the welding gun, press the power supply test gas supply switch to detect the gas flow. 2. When the gas protection effect is not good and the weld seam has pores, the gas flow meter can be used to measure the terminal gas flow of the shielding gas and detect whether the gas flow is insufficient. 2 It is used to measure the gas flow at the nozzle of MIG, MAG or TIG welding gun. 3 Simply place the flowmeter on the MIG, MAG welding or TIG gas nozzle and measure the gas flow from the top of the ball. 4 It is applicable to Ar or CO2 gas or its mixture. 5 The general measurement range is 1-25L/min. Package Included: 1 * Gas flow meter
