A WELDER FOR ALL SEASONS - Make the Ranger 305 G your portable welding station for general stick and downhill pipe, Touch Start™ TIG, MIG, and flux-cored wire capability. The 9,500 watt continuous single-phase AC generator powers motors starting, tools and inverter welders for extended range and process capability.
The Ranger 305 G features digital weld meters that monitor actual welding output, making it easy to precisely pre-set your procedures and track performance in real-time. With a generous 12-gallon fuel capacity, the unit allows for extended operation on job sites without frequent refueling interruptions. The electric fuel pump helps avoid vapor lock during high-altitude operation, ensuring reliable performance in challenging environments. Powered by a robust 23 HP Kohler carburetor gasoline engine, the Ranger 305 G delivers excellent DC multi-process welding capabilities for general purpose stick, downhill pipe welding, TIG, cored-wire, and MIG applications using CO2 and mixed gas. This is the only compact gasoline welder in North America rated at 29V for 300 amps of stick or CV welding, providing exceptional power in a portable package.
The Ranger 305 G incorporates Lincoln Electric's proven Chopper Technology® which provides easy starts, a smooth arc, low spatter, and optimal bead appearance for superior welding results. Beyond welding capabilities, the unit serves as a powerful generator with 10,500 watts peak single-phase AC generator power and 9,500 watts continuous output for high capacity needs such as back-up power generation or operating Lincoln Electric Invertec® inverter welders. The AC generator maintains constant voltage at 120V or 240V at any weld dial setting, providing clean power for lights, grinders, and other power tools. The innovative skewed rotor design provides AC power suitable for operating Lincoln Electric inverter power sources - a feature Lincoln Electric pioneered in the welding industry. Built for rugged reliability, both welding and AC generator outputs are rated for operation at 104°F (40°C), ensuring dependable performance in extreme conditions. The Ranger 305 G represents the perfect balance of portability, power, and versatility for contractors, pipeline welders, maintenance crews, and fabricators who need a reliable all-season welding solution for remote locations and demanding applications.

Yes — this is a factory demo or low-hour unit directly from Lincoln Electric. Units may show light cosmetic marks from display use but are mechanically sound. The warranty on this unit is the same as on a new machine. Lincoln’s Industrial Limited Warranty (form IMWS1, Apr-2026) lists a 3-year warranty period for “All Lincoln welding machines, wirefeeders & plasma cutting machines”, and Lincoln states: “Lincoln will assume both the parts and labor expense of correcting defects during the warranty period.” As on a new machine, the engine is not covered by Lincoln’s warranty — Lincoln states: “All engines and engine accessories are warranted by the engine or engine accessory manufacturer and are not covered by this warranty.” This machine’s Kohler OHV Command CH730 engine is warranted by Rehlko (formerly Kohler): “Three Years”, and that term “BEGINS ON DATE OF PURCHASE BY END USER.” Lincoln footnotes the Rehlko (formerly Kohler) three-year term “First owner only.” Lincoln directs buyers to the engine maker — WWW.ENGINES.REHLKO.COM / 1-800-544-2444 Rehlko Service Department.

This factory demo unit is supplied as the machine only, verified directly by WeldingMart’s owner. Lincoln’s English product page for K1726-5 is retired (404), so Lincoln publishes no included-items list for this product number. Not included: welding leads (electrode and work cable), electrode holder, work clamp, and accessory kits. No printed operator’s manual, WeldingMart demo-prep certification document or Lincoln warranty registration paperwork ships with the machine. Consumables (electrodes, gas cylinders) are not included. Leads, holders, clamps, cable connectors, undercarriages, spark arrestors, remote controls and wire feeders are sold separately — contact WeldingMart and we will quote the exact set you need.
