The Lincoln Electric Lincoln PIPEFAB Engine-Driven Welder Generator is a purpose-built multi-process welding system engineered specifically for pipe fabrication and structural pipe welding applications. Integrating a high-performance power source with a wire feeder, the PIPEFAB Ready-Pak supports MIG (GMAW), Pulse MIG (GMAW-P), Flux-Cored (FCAW), and Stick (SMAW) processes optimized for the welding procedures used by pipe fabricators, spool shops, and construction contractors.
The PIPEFAB system is engineered around Lincoln Electric's advanced waveform technology with specific pipe welding programs designed to optimize root-pass, fill-pass, and cap-pass weld quality. Its Ready-Pak configuration delivers an integrated, deployment-ready system that minimizes setup time and system integration complexity for pipe shops and prefabrication facilities. The U3734-1 is a low-hour factory-certified demo Ready-Pak offering the same complete system capability at a significantly reduced price.
