Lincoln Ranger® 305 D Engine Driven Welder (Kubota®)

Lincoln Ranger® 305 D Engine Driven Welder (Kubota®)

Product Description


  • Simple Controls - Keep training time to a minimum with the straightforward control panel of the Ranger® 305 D. The flip-down control panel door keeps less frequently used controls out of the way.
  • Single, full-range output control dial. No confusion with taps and controls!
  • 4 welding modes: CC-Stick, Downhill Pipe, CV-Wire, and DC Touch Start TIG®.
  • Dual digital output meters for presetting weld amps for stick, TIG or downhill pipe modes, or voltage for CV wire mode. Also displays actual outputs while welding. Memory feature holds output readings for 7 seconds after welding stops for viewing by the operator.
  • Output at welding terminals controlled by electronic contactor. Can be switched to “On”, or to “Remotely Controlled”.
  • Remote is auto-activated when plugged into a 6-pin connector. For the CC-stick, downhill pipe and Touch Start TIG® modes, the machine output dial becomes a maximum current limit for more fine tuning with the remote control dial or Amptrol™.
  • Compatible with many Lincoln wire feeders including the LN-25 Ironworker™, LN-15, LF-72, LF-74, LN-7 GMA, LN-742, LN-8 wire feeders and Magnum® SG Spool Gun.
  • Wire feed voltmeter switch matches polarity of wire feeder volt meter to polarity of electrode.
  • Top-of-the-line water-cooled Kubota® 18.8 HP D722 diesel engine with electric start. EPA Tier 4 Final.
  • Fully enclosed case for equipment protection and low noise. Noise at rated load:
    – 104.2 dB sound power (Lwa)
    – 80.6 dBA sound level at 23 ft. (7 m)
  • Glow plugs for rapid starting down to 5°F (-15°C).
  • Mechanical fuel pump is activated when glow plug button is pressed

  1. High Altitude: For maximum rating, derate the output 2.5% to 3.5% for every 1,000 ft. (300 m). High Temperature: For maximum rating, derate 2 volts for every 18°F (10°C) above 104°F (40°C). See Operator Manual for additional information.
  2. DC constant voltage capability provides convenience and added safety when welding in electrically hazardous conditions.
  3. When welding, available auxiliary power will be reduced. Output voltage is within +\- 10% at all loads up to rated capacity.
  4. 120V will operate either 60 Hz or 50/60 Hz power tools, lights, etc.
  5. Circuits cannot be wired in parallel to operate the same device.
  6. Engine warranted separately by engine manufacturer.
