The DLW300ESA1 Diesel-Powered Welder/Generator is a premier choice for professionals seeking a versatile, durable, and efficient machine for industrial welding and onsite power needs. Combining robust welding performance with powerful generator capabilities, this model is engineered to deliver maximum productivity and reliability in harsh environments and demanding job sites.

Overview of the DLW300ESA1 Diesel-Powered Welder/Generator

The DLW300ESA1 stands out by offering up to 300 amps of welding current and 10.5 kW of clean AC generator power in a single compact package. This dual-functionality ensures users can efficiently perform rigorous welding tasks while simultaneously powering essential jobsite tools and equipment. The machine is built around a Tier 4 Final Kubota D722 diesel engine known for longevity, fuel efficiency, and reduced emissions, making it environmentally compliant and dependable under continuous heavy use.

Key Features and Innovations

• Delivers a maximum 300 amps for welding and produces 10.5 kW as a generator, covering both single- and multi-phase needs.

• Supports a full suite of welding processes, including SMAW (Stick), FCAW (Flux-cored), GMAW (MIG), GTAW (TIG), and ACAC (Air Carbon Arc Cutting).

• Users can draw ample AC power while welding, allowing for uninterrupted operation of lights, pumps, compressors, and other tools alongside welding tasks.

• Outstanding voltage regulation at ±1.5% ensures stable output for sensitive electronics and precision tools.

• Features Arc Force control for smoother, higher-quality arcs and E-mode for low fuel consumption, allowing users to weld at idle up to 160 amps—ideal for light fabrication and maintenance tasks.

Technical Specifications

Advanced Performance Benefits

The DLW300ESA1 utilizes state-of-the-art Arc Force control, allowing operators to fine-tune DC output during difficult welding conditions and preventing electrodes from sticking during short-arc-length operations. This guarantees smooth arc starts, uniform penetration, and high-quality welds regardless of project complexity.

E-mode further enhances efficiency by letting users weld up to 160 amps at idle, dramatically reducing fuel consumption, operating noise, and overall costs. This feature is perfect for light-duty work and maintenance applications where full output isn't required, supporting sustainable work practices and substantial cost savings.

Simultaneous Welding and Power Generation

With the ability to generate AC power while welding, the DLW300ESA1 acts as a mobile jobsite powerhouse. Its tightly regulated voltage output protects even the most delicate jobsite electronics, so operators can run grinders, fans, lighting, and communications equipment without interrupting welding tasks.

Noise Reduction and Jobsite Compliance

One of the quietest diesel welders in its class, the DLW300ESA1 produces only 59 dBA at 23 feet, allowing for operation in noise-sensitive environments such as hospitals, schools, or residential areas. The sound-attenuated cabinet and full GFCI-protected panel meet OSHA and NEC standards for workplace safety, making this machine suitable for virtually any public or private sector jobsite.

Versatility and Multi-Process Capability

Supporting stick, MIG, TIG, flux-cored, and air carbon arc gouging processes, the DLW300ESA1 is designed for maximum flexibility. From heavy structural fabrication to fine TIG repairs, this unit’s capabilities ensure users can handle almost any fabrication or repair job on the same platform.

Rugged Build and Low Maintenance

Built with a heavy-gauge steel housing and protected control panel, the DLW300ESA1 is engineered for hard jobsite use. Routine maintenance is straightforward with externally accessible fluid drains for oil, fuel, and coolant—keeping downtime to a minimum. Kubota’s Tier 4 engine offers reliable, low-emission performance with extended service intervals, adding to the machine’s low total cost of ownership.

User-Focused Design and Options

• Ergonomic lifting bale and convenient points for hoisting and truck bed mounting.

• Full instrumentation with vandal-resistant LED display for instant readout of load and machine status.

• Available options include lightweight or heavy-duty trailers (with up to a 28-gallon fuel capacity), remote controls, welding cable carriers, toolboxes, cold-weather kits, and more—allowing total customization for unique site needs.

Safety and Environmental Controls

Automatic safety shutdowns for water, oil level, and DC thermal overload protect both the operator and the investment, enabling worry-free performance on long shifts or in extreme weather. The model’s full GFCI protection, OSHA and NEC compliance, and minimal emissions further guarantee peace of mind.
