The Lincoln Electric Lincoln Frontier 400X Pipe Kubota Engine-Driven Welder Generator is a Kubota diesel-powered engine-driven welder/generator purpose-engineered for professional pipe welding applications. Delivering multi-process capability optimized for pipeline construction and pipe fabrication — including Stick (SMAW), MIG (GMAW), Flux-Cored (FCAW), and TIG (GTAW) processes — the Frontier 400X Pipe provides the arc characteristics and power output demanded by certified pipe welders working in the field.
Pipe welding demands precise arc control across all positions, including vertical-up fill passes and overhead caps. The Frontier 400X Pipe's Lincoln Electric arc technology and Kubota diesel engine combine to deliver the output stability and fuel efficiency required for extended pipeline construction campaigns and remote pipe spool fabrication. The U3485-2 is a factory-certified demo unit available at a reduced price with full Lincoln Electric performance verification.
