101C - Powerweld CO2 Flowmeter Regulator CGA-320

Precision CO2 Gas Control for Industrial Applications

The Powerweld 101C Regulator / Flowmeter is a specialized gas control device engineered specifically for the regulation and measurement of Carbon Dioxide (CO2) in welding and industrial environments. Unlike standard pressure regulators that rely solely on diaphragm gauges, this unit utilizes a vertical flow tube design, providing a visual and highly accurate reading of gas flow in Cubic Feet per Hour (CFH). This distinction is critical in industrial settings where precise shielding gas coverage is required to prevent porosity and ensure weld integrity.

Constructed from high-quality machined brass, the body of the 101C is built to withstand the rigors of daily shop use. The internal mechanism is designed to reduce the high cylinder pressure of CO2 down to a working pressure suitable for the flowmeter tube. The unit features a CGA-320 inlet connection, which is the industry standard for Carbon Dioxide cylinders in North America. This connection requires the use of a sealing washer (typically fiber or nylon) to ensure a leak-free seal, a crucial safety and efficiency factor when working with compressed gases.

The flowmeter tube is made from impact-resistant polycarbonate and is calibrated specifically for the density of CO2 gas. It offers a flow range typically between 0 and 60 CFH, covering the vast majority of MIG welding applications, from light sheet metal work to heavy structural fabrication. The adjustment knob allows for smooth, linear control of the gas output, enabling operators to fine-tune their shielding gas consumption to minimize waste while maintaining adequate coverage. The unit is also backpressure compensated, meaning the flow reading remains accurate even if there is resistance downstream in the hose or torch.

Safety features include an internal pressure relief valve designed to vent excess pressure should a malfunction occur, protecting the low-pressure components and the operator. The outlet connection is a standard 5/8"-18 RH female fitting, making it compatible with standard inert gas hoses used in the welding industry. For maintenance and repair operations (MRO) and procurement specialists, the Powerweld 101C represents a reliable, cost-effective solution for CO2 gas management.
