Diesel Welder Generators
A quality diesel welder generator is essential for mobile welding operations, remote construction sites, and rental fleets requiring independent power and welding capability. Our comprehensive range includes professional-grade diesel welder generators from Site-Arc, featuring robust Yanmar diesel engines, and Arc-Gen machines delivering super-silent operation and advanced fuel efficiency. Whether you need a portable 200-amp mobile solution or a powerful 500-amp skid-mounted unit with 15KVA generator capability, we stock the equipment for every welding demand. With many options offering and site tow options, our diesel welding generators combine durability, fuel efficiency, and reliable performance for professionals who can't compromise on power.
Professional Diesel Welder Generators for On-Site & Mobile Welding
Portable & Towable Diesel Welders: Freedom to Weld Anywhere
Our diesel welder generator range includes mobile and towable options that bring professional welding capability directly to remote job sites, construction projects, and maintenance locations. From the compact 200-amp WDY-200-DC with carrier frame, inbuilt tool tray, and foam-filled wheels for effortless transport, to larger skid-mounted models, each diesel welding generator is engineered for mobility without sacrificing performance. Whether you choose a Site-Arc or Arc-Gen model, these portable diesel welders deliver consistent, high-capacity DC welding power plus reliable auxiliary output to run additional tools and equipment simultaneously on-site. The flexibility to position your diesel welder exactly where you need it eliminates costly site infrastructure and power supply challenges.
Yanmar & Kubota Engines: Fuel-Efficient Power You Can Rely On
Engine quality defines reliability in diesel welder generators, and our selection prioritises proven industrial powerplants. Site-Arc machines feature robust Yanmar diesel engines with multi-voltage auxiliary power and advanced chopper technology, engineered for demanding environments. Arc-Gen models utilise Kubota water-cooled, electric start diesel engines, consuming just 2.32 litres per hour on the 330CCCV model whilst delivering superior performance. Both manufacturers prioritise fuel efficiency without compromising welding capability -critical for extended runtime and cost-effective operation on extended job sites.
Multi-Amperage Range: 200A to 500A for Every Welding Application
Our diesel welder generator selection spans 200-amp to 500-amp welding output, giving you flexibility to match machine capability to your specific application requirements. The Site-Arc WDY500-DC delivers 500A DC welding with 15KVA generator output, engineered with high-capacity CC and CV output for both MMA and MIG wire feed welding. Arc-Gen's 300AVC offers super-silent operation at 66dB with 300A output and up to 10.5 hours uninterrupted runtime from a 19-litre fuel tank. The 400CCCV delivers 400A capacity handling electrodes up to 8mm with both constant current and constant voltage modes. Each portable diesel welder in this range is optimised for continuous duty welding, whether you're handling routine fabrication, pipeline work, or heavy-duty arc gouging.
