K2707-2 - Lincoln Outback 145 Kohler Engine Driven Welder Generator

Technical Overview of the Lincoln Outback 145

The Lincoln Electric Outback 145 (SKU: K2707-2) is a compact, engine-driven welding solution designed for service trucks, maintenance crews, and remote fabrication tasks. Engineered for durability and performance, this unit integrates a DC stick welder with a robust AC generator, powered by an industrial-grade 8.9 HP Kohler CH395 gasoline engine. The engine features a single-cylinder, 4-cycle overhead valve design with recoil start, ensuring reliable ignition and operation in various environmental conditions. With a substantial 6.8-gallon (25.7-liter) fuel tank, the Outback 145 offers extended operational periods, reducing downtime associated with frequent refueling. Fuel consumption is efficiently managed, rated at approximately 0.82 gallons per hour at 80 amps DC output.

Structurally, the Outback 145 is built to withstand harsh job site environments. It features a 1-1/4 inch (32 mm) diameter rugged tube frame, which is the largest in its class, providing exceptional protection for the engine and internal components. A key design innovation is the inclusion of Low-Lift Grab Bars (patent pending), which offer additional leverage points to facilitate safer and easier lifting of the 234 lb unit onto truck beds or elevated platforms. The machine's footprint is compact, with dimensions of 25.50 x 21.20 x 31.50 inches, optimizing cargo space in service vehicles.

In terms of output, the welder delivers up to 145 amps of DC current, suitable for a wide range of stick electrodes up to 1/8 inch (3.2 mm) in diameter. The DC output ensures a smooth, stable arc for high-quality welds on steel and stainless steel. Simultaneously, the unit functions as a powerful generator, providing 4,750 watts of peak single-phase AC power and 4,250 watts of continuous power. This auxiliary power capability is sufficient to run grinders, work lights, pumps, and power tools. Furthermore, the generator output is clean enough to power inverter-based welding sources; users can plug in a Lincoln POWER MIG 140C or POWER MIG 180C directly, effectively expanding the unit's capabilities to include wire welding processes without the need for adapters.
