A high speed, diesel engine-driven welder/generator capable of dual or single operator DC multi-purpose welding. The machine features 220 VAC single phase and 380 VAC three phase auxiliary power, a user interface screen for advanced features, and patented Chopper Technology®. Powered by a 26.4 hp Perkins® D403-11 diesel engine. Not Available in the US, Canada, or EU.






Built for the construction site, the pipeline, and the rental fleet, the Dual Maverick® 450 is two complete welders in one. This best-in-class arc welding machine provides substantial power to multiple welding arcs, runs quietly, and promotes fuel savings with variable engine RPM and auto start/stop capabilities. Operators can be easily set for two operators to weld at the same time, or for one operator to gouge with up to a 3/8 in. (9.5 mm) carbon. Additionally, the machine boasts an advanced user interface on two heavy-duty 4.3” weatherproof LCD screens. These easy setup screens host intuitive user functionalities to keep things simple.


  • Optimized Operations – Utilizes a single engine to offer two welding arcs with up to 200 amps of output or choose single operator mode for one arc up to 450 amps of output to promote a more efficient welding environment. Save space and make transportation easier moving one machine instead of two!
  • Advanced User Interface – Features two 4.3″ weatherproof LCD screens with an intuitive interface to provide easy setup and increased functionality, and automatically notifies operators of upcoming maintenance needs to help keep the machine running at peak performance.
  • Quiet Operation – Designed to run at lower noise levels to allow for vital directions or control-related communication near the welding machine to help promote a safer and more ideal welding environment by reducing worksite noise.
  • Industrial Diesel Engine – Powered by a 26.4 hp, naturally aspirated Perkins® diesel engine for smooth and quiet operation.
