The Lincoln Electric PIPEFAB™ Welding System (K3731-1) is a comprehensive solution engineered specifically for the rigorous demands of the pipe and vessel fabrication industry. This Ready-Pak™ integrates cutting-edge power source technology with a robust wire feeder and a complete accessory package, delivering a turnkey setup for high-level production environments. At the core of the PIPEFAB™ system is its breakthrough arc performance, which includes the improved Surface Tension Transfer (STT®) process. This technology provides a superior root pass solution, offering faster travel speeds and exceptional stability compared to traditional methods. Additionally, the system features Smart Pulse™ Technology, which enhances puddle control and arc stability for out-of-position welding, ensuring high-quality results from root to cap.
Designed with industrial versatility in mind, the PIPEFAB™ system utilizes PowerConnect® Technology, allowing it to automatically adjust to input power ranging from 200V to 600V, 50 or 60 Hz, three-phase. This flexibility makes it an ideal choice for facilities with varying power infrastructures or for mobile fabrication units. The machine supports a wide array of processes including Stick, DC TIG (High Frequency & Touch Start), MIG, Pulsed MIG, Flux-Cored, and STT, making it a true multi-process workhorse. The system's architecture is built around reliability and efficiency; it features dedicated, electrically isolated process outputs. This design innovation means operators never have to swap cables when switching between TIG, Stick, or Wire processes, significantly reducing setup time and wear on connectors.
The K3731-1 package is meticulously curated to include everything needed to start welding immediately. It comes standard with the PIPEFAB™ Power Source and Feeder, a heavy-duty Cart with a Dual Bottle Rack for mixed gas operations, and two premium Magnum® PRO Curve™ welding guns (200 amp and 300 amp models). Also included are essential consumables such as tapered contact tips, flush nozzles, and multiple drive roll kits for different wire sizes and types. This comprehensive approach ensures that the PIPEFAB™ system is not just a machine, but a complete fabrication partner ready to tackle the most challenging pipe geometries and materials.
