- Excellent DC multi-process welding for general purpose stick, downhill pipe (stick), TIG, cored-wire, MIG (CO2and blended gas) and arc gouging.

• Digital Weld Meters

- Digital weld meters for amps and volts makes it easy to precisely pre-set your procedures and monitor actual welding output.

• Superior Arc Performance

- Lincoln’s Chopper Technology provides easy starts, a smooth arc, low spatter and excellent bead appearance.

Gasoline Engine

305G is built with a totally

305G ...

• 10,500 Watts Peak Single-Phase AC Generator Power

- 10,500 watts peak for motor starting. 500 watts more!

- 9,500 watts contiuous for high capacity needs such as a back-up generator, powering a Pro-Cut

plasma cutter or an Invertec

inverter welder. Also for lights, a grinder or other power tools.

• Skewed Rotor Design

PERFORMANCE

Welding Performance

• Provides superior DC arc welding performance for stick, TIG, cored-wire, MIG and arc gouging.

• Lincoln Chopper Technology.

- Easy Starts.

- Smooth Arc.

- Low Spatter.

- Excellent Bead Appearance.

• CC-Stick mode is optimized for general purpose stick using E7018 low hydrogen electrode.

• Downhill Pipe welding mode is excellent for cellulosic electrodes, such as Fleetweld®5P+. Fast travel speeds, especially on fill passes. Arc control adjustment for a softer, buttery arc, or a more forceful, digging arc.

• Arc force control provides a soft or more forceful digging arc in CC-stick or downhill pipe mode and inductance/pinch control in CV wire mode.

• Built-in “hot” start for easier starts and restrikes minimizing the electrode “sticking” to the work.

• Touch-Start DC TIG™ - lift tungsten to start the arc. No high frequency required. Avoids tungsten contamination in the weld. Voltage sensing output stops the arc when the torch is lifted at the end of the weld - increased operator appeal.

• Arc gouging with up to 3/16” (4.8 mm) carbons.

AC Generator Performance

• 10,500 watts peak AC generator power. Use for motor starting.

• 9,500 watts continuous AC generator power. For high capacity needs such as a back-up generator, powering a Pro-Cut cutter or an Invertec

inverter welder. Also for lights, a grinder or

plasma

other power tools.

• Up to 40 amps at 240V from the 120V/240V receptacle with weather resistant cover. Circuit breaker protection.

• Two 120V 20 Amp duplex receptacles with weather resistant covers. Circuit breaker protection. Will operate up to 9” grinder.

• Maximum generator power (while not welding) is available at any weld dial setting.

• Skewed rotor design provides AC power suitable for operating Lincoln plasma cutters and inverters.

FEATURES

• Simple Controls - Keep training time to a minimum with the straightforward control panel of the Ranger 305G. 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 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 output control is auto-activated when plugged into a 6-pin connector.

• Compatible with many Lincoln wire feeders including the LN-15, LN-25, LN-35, LN-23P, LF-72, LF-74, LN-7, LN-7 GMA, LN-742, LN-8, Cobramatic™ wire feeders and Magnum SG Gun.

• Wire feed voltmeter switch matches polarity of wire feeder volt meter to polarity of electrode.

• Top-of-the-line Kohler OHV 23 HP Command

• 12 gallon fuel capacity allows you to run an extended day.

20% longer than competitive machines.

engine.

• Fully enclosed case for equipment protection and low noise. Lower noise than partially-enclosed welders of comparable size. You can hear the difference! Noise at rated load:

– 101.3 dB sound power (Lwa) – 76.7 dBA sound level at 23 ft. (7m)

• Choose mechanical or electric fuel pump.

– Mechanical for most environments. – Electric fuel pump avoids vapor lock. Assures consistent fuel

delivery in locations having a combination of high altitude, warm ambient temperatures, and high anti-pollution additives in gasoline.

• Electric fuel gauge located on control panel makes it easy to

check the fuel level during operation. Helps you eliminate running low on fuel during critical jobs.

• Large top fuel filler neck is easily accessed for refueling.

• Electric start. Engine battery charging system light to indicate abnormal charging.

• Oil drain valve (no tools required) with removable extension tube.

• Convenient truck or trailer mounting with front and rear holes in base.
