Energysaving Argon Gas Meter: The AR191 external thread pressure gauge is designed to effectively measure argon gas pressure while reducing gas wastage through an energysaving design. This helps lower operational costs and promote efficient gas use. CGA580 Thread for Easy Connection: The inlet features a CGA580 thread for a secure, leak connection to argon gas tanks. This enables quick, hassle installation and reliable performance in daily use. Accurate Pressure Measurement: The AR191 has a brass exterior for durability and a pressure range suitable for precise argon gas readings. It provides dependable, precise measurements to support stable welding conditions. Convenient Outlet Nozzle: An 8 mm outlet nozzle allows easy attachment to hoses and other equipment, delivering smooth gas flow and efficient operation during welding processes. Practical use scenarios: TIG welding of aluminum or stainless steel: Monitor and control argon shielding pressure to maintain arc stability and gas efficiency during welding. Argon gas cylinder setup and routine welding maintenance: Connect to the gas tank via CGA580, verify pressure levels, and ensure consistent supply with minimal waste. Workshop gas line use and purging: Attach quickly to hoses and equipment with the 8 mm nozzle for reliable argon flow during setup and testing.
