Lincoln Outback 145 Engine Driven Welder Kohler – K2707-2

The Lincoln Outback 145 (K2707-2) is a compact, lightweight engine-driven welder/generator built for one-person portability and field reliability — delivering up to 145 amps of DC stick welding output and 4,250 watts of continuous AC generator power from a 8.9 HP Kohler CH395 gasoline engine. At just 234 lbs (106 kg), it is the go-to machine for service trucks, fence contractors, pipeline maintenance crews, farmers, ranchers, and any professional who needs both welding capability and auxiliary power without access to grid electricity.
The Outback 145 is purpose-built for portability without sacrificing protection. Its 1-1/4 inch (32 mm) diameter tube frame — the largest in its class — provides superior impact resistance for machines that get loaded, unloaded, and moved daily. Low-Lift Grab Bars at both ends reduce the effort required to maneuver the unit onto and off truck beds and into confined spaces, while providing additional bumper protection during transport. The large 6.8-gallon (25.7 L) fuel tank delivers extended runtime before refueling, keeping crews productive through long work sessions in locations where fuel access is limited.
The Outback 145 handles stick welding with up to 1/8-inch (3.2 mm) electrodes for general maintenance, repair, and light fabrication — carbon steel, cast iron repair, and hardfacing. Its DC output provides stable arc characteristics for out-of-position and overhead work. When a wire feeder is needed, the Outback 145 is compatible with Lincoln Electric wire feeders including the POWER MIG 140C and POWER MIG 180C for MIG and flux-cored wire processes, significantly expanding application flexibility for general fabrication. The 4,750-watt peak / 4,250-watt continuous generator output supports grinders, work lights, water pumps, battery chargers, and other field equipment.
Why choose the Lincoln Outback 145?
The Outback 145 fills the gap between a compact portable generator and a full-size engine-driven welder. For farm and ranch operations where a single machine needs to fix fence posts and power a work light, for rural pipeline maintenance crews who handle occasional stick repairs on small-diameter pipe and utility lines, and for service technicians who need a machine that fits in a truck bed and won’t require two people to move it — the Outback 145 delivers. The Kohler CH395 engine is a proven, parts-available platform. The Lincoln Electric brand stands behind every unit with comprehensive warranty support. No other machine in this weight class matches the Outback 145’s frame protection and Low-Lift grab bar system.
