K3734-1 - Lincoln PIPEFAB Multi-Process Pipe Welding System

Advanced Pipe and Vessel Fabrication System

The Lincoln Electric PIPEFAB™ Ready-Pak® (K3734-1) is a revolutionary welding system engineered specifically for the demanding environments of pipe and vessel fabrication. Designed from the ground up to address common industry pain points, the PIPEFAB system integrates cutting-edge technology with rugged reliability. At its core is the breakthrough arc performance that supports a wide range of processes including Stick, DC TIG, MIG, Pulsed MIG, Flux-Cored, and the industry-renowned Surface Tension Transfer (STT®) process. This allows for high-quality results from the root pass to the cap, ensuring structural integrity and efficiency in every weld.

One of the standout technical innovations of the PIPEFAB system is its proprietary Cable View™ Technology. This feature continually monitors cable inductance and automatically adjusts the waveform to maintain consistent arc performance, regardless of whether the cables are long or coiled. This is critical in large fabrication shops where cable management can often lead to variable weld quality. Additionally, the system features PowerConnect® Technology, offering incredible input power flexibility ranging from 200V to 600V, making it adaptable to various shop power configurations without manual linking.

The user interface is designed for unmatched simplicity. With one-button process changes and straightforward digital navigation, operators can switch between modes instantly. The machine also features dedicated, electrically isolated process outputs for Stick, TIG, and Wire processes. This "Industry Driven Design" means welders never have to swap cables when changing processes, significantly reducing downtime and setup errors. The Ready-Pak configuration provides a turnkey solution, including the power source, wire feeder, cart, dual bottle rack, and two Magnum PRO Curve guns, ensuring you have everything needed to start fabricating immediately.
