Overview
The Computer Weld A0A0036 GTFM IV is a 120 VAC in-line gas turbine flow monitor engineered for precise measurement of welding shielding gas flow rates. This compact, industrial-grade instrument is designed to integrate directly into welding gas delivery lines, providing real-time monitoring of gas flow to ensure consistent shielding during arc welding operations. The system supports both English and metric measurement scales.
