Lincoln Maverick 325X Kubota Engine-Driven Welder/Generator - K3581-1
The Lincoln Maverick 325X (K3581-1) represents a revolutionary advancement in portable welding technology, delivering exceptional performance in a remarkably compact and efficient package. Weighing just 750 lbs (340.2 kg) and measuring 34.23 in x 21.25 in x 54.29 in, this innovative engine-driven welder/generator offers an optimal balance of power, portability, and advanced features for demanding field applications. Powered by a reliable 24.8 HP Kubota D902 naturally aspirated diesel engine that meets EPA Tier 4 Final emissions standards, the Maverick 325X provides substantial welding capability with 325 amps of output (IEC rated at 325A/33V at 100% duty cycle in extreme 104°F/40°C conditions) alongside 10 kW of clean, single-phase auxiliary power for tools and equipment, all while delivering significant fuel savings through its intelligent variable engine RPM and auto start/stop technology.
The Maverick 325X features a sophisticated digital interface with a heavy-duty 4.6-inch weatherproof LCD screen that provides unprecedented control over machine functions, including comprehensive process setup, maintenance reminders, and PIN authorization to prevent unauthorized use. This advanced user interface simplifies operation while maximizing productivity across diverse applications. The system's multi-process capabilities support stick welding, TIG, MIG, and flux-cored applications, with specialized modes optimized for each process and direct-connect spool gun compatibility for enhanced aluminum welding performance. The integrated CrossLinc Technology enables remote parameter adjustment directly at the arc without additional control cables, dramatically improving productivity, safety, and weld quality in challenging field environments by eliminating trips to the power source and reducing jobsite clutter.
Engineered for operational efficiency, the Maverick 325X incorporates intelligent power management features that significantly reduce operating costs and environmental impact. The variable engine RPM functionality automatically adjusts engine speed based on power demand, reducing fuel consumption and noise levels during idle periods or low power requirements. This is complemented by the Auto-Stop/Start technology, which automatically shuts down the engine during extended idle periods and restarts it when welding or power is needed, further minimizing fuel consumption, engine wear, and maintenance requirements. The system's 11.5-gallon (50 L) fuel tank provides extended runtime between refueling, while the remarkably quiet operation with sound levels as low as 73.5 dB at idle enhances operator comfort and facilitates better communication on the jobsite. With its comprehensive 3-year warranty, exceptional portability, advanced technology integration, and industry-leading fuel efficiency, the Lincoln Maverick 325X establishes a new benchmark for portable engine-driven welders that maximize productivity while minimizing operational costs across construction, maintenance, and field fabrication applications.
