K3697-1 - Lincoln Electric In-Line Gas Flow Sensor Kit

Precision Gas Monitoring for Industrial Welding

The Lincoln Electric K3697-1 CWT GFM Gas Flow Monitor is an essential accessory for high-stakes industrial fabrication environments where weld quality cannot be compromised. Designed to integrate directly with advanced Lincoln Electric wire feeders, this in-line device provides continuous, real-time monitoring of shielding gas flow. By ensuring that the gas flow rate remains within the specified Welding Procedure Specification (WPS) parameters, the K3697-1 acts as a critical safeguard against common weld defects such as porosity and oxidation.

For facilities utilizing bulk gas systems or complex manifold setups, maintaining consistent pressure and flow at the arc can be challenging. This monitor bridges the gap between the gas supply and the weld pool, offering immediate feedback to the operator and the power source. If the gas flow drops below the user-defined threshold—whether due to a kinked hose, an empty cylinder, or a regulator issue—the system can trigger an alarm or stop the welding process entirely, preventing the production of scrap parts.

Seamless Integration and Data Tracking

Beyond simple monitoring, the K3697-1 is a key component of a data-driven welding operation. When paired with Lincoln's Power Wave® technology and CheckPoint™ production monitoring software, this device allows fabrication managers to track gas usage trends, verify compliance for every weld made, and identify inefficiencies in gas consumption. This level of transparency helps in accurately costing jobs and reducing shielding gas waste, which is often a significant hidden cost in welding operations.

Robust and Easy to Install

The unit is designed for the rugged reality of the shop floor. Its compact form factor allows it to be installed in-line with the gas hose at the back of the wire feeder, keeping it protected while remaining accessible. It draws power and communicates directly through the feeder's internal connections, eliminating the need for bulky external power supplies or complex wiring harnesses. Whether you are welding stainless steel, aluminum, or mild steel, the K3697-1 ensures your shielding gas coverage is always exactly where it needs to be.
