ENGINE DRIVEN WELDERS
Diesel Engine-Driven Welder
- A powerful 300 amp DC CC/CV diesel engine-driven welder. All
rated outputs at 100% duty cycle 104°F (40°C).
Multi-Process Welding
- Excellent DC multi-process welding for general purpose stick,
downhill pipe (stick), TIG, cored-wire, MIG (CO
2
and 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.
Plenty of AC Generator Power
- A portable powerhouse delivers 10,000 watts peak (9,500 watts
continuous) of 120V/240V AC generator power. Enough
power to run lights, tools, and weld at the same time!
- AC generator voltage is constant at 120V or 240V at any weld dial
setting.
Skewed Rotor Design
- Skewed rotor design provides AC power waveshape suitable for
operating Lincoln Pro-Cut
®
plasma cutters and inverter power
sources. Lincoln was first in the welding industry with this feature.
One-Pak
®
Package
- Convenient way to order a welding system. See inside.
Three-Year Warranty
- Three-year Lincoln warranty on welder (engine is warranted
separately by the engine manufacturer).

Welding Performance
Provides superior DC arc welding performance for stick, TIG,

Lincoln
Chopper Technology.
CC-Stick mode is optimized for general purpose stick using
E7018 low hydrogen electrode.
Downhill Pipe welding mode 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.
Arc gouging with up to 3/16 (4.8 mm) carbons.
Touch-Start DC TIG
®
lift tungsten to start the arc.
AC Generator Performance
Two 120V 20A GFCI (ground fault circuit interrupter) duplex
receptacles with weather resistant covers. Circuit breaker
protection for, among tools, up to 9 grinder.
Up to 40 amps at 240V from the 120V/240V receptacle with
weather resistant covers. Circuit breaker protection.
AC generator voltage is constant at 120V or 240V at any weld
dial setting.

FEATURES
Simple Controls - Keep training time to a minimum with the
straightforward control panel of the Ranger
®
305D. 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 read-
ings 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 downhill pipe mode the machine output dial becomes
a maximum current limit for more fine tuning with the remote
control dial.
Compatible with many Lincoln wire feeders including the LN-25
PRO, LN-15, LN-23P, LF-72, LF-74, LN-7, LN-7 GMA, LN-742,
LN-8, Cobramatic 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
®
18.8HP D722
diesel engine with electric start.
EPA Tier 4 Final.
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:
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).
Electric fuel pump and automatic air-bleed system virtually
eliminates manual air bleeding if fuel tank is run dry. Activated when
glow plug button is pressed.
Patented and award-winning Lincoln
Chopper Technology
delivers superior DC arc welding performance for general purpose
stick, Downhill Pipe, DC TIG, MIG, cored-wire and arc gouging.
Benefits of Chopper Technology include:
- Easy arc starting
- Smooth arc action
- Low spatter levels
- Excellent bead appearance
WHAT IS TOUCH-START
®
TIG?
Traditional weld control is more
variable around the desired output.
Chopper Technology
delivers extremely fast response
for tighter output control.
WHAT IS CHOPPER TECHNOLOGY?
Touch-Start TIG uses a very low voltage to sense when the
tip of the tungsten electrode is touched to the work piece. When
this occurs, a complete circuit is established. When the tungsten
is then raised from the work piece, the circuit senses a change
in voltage and initiates the appropriate welding current and
voltage to support the TIG welding process.
Enjoy the added benefits of Lincolns Touch-Start TIG when
DC TIG welding. Not only do you avoid tungsten contamination
when arc starting, but you also dont need extra high frequency
equipment. Voltage sensing output stops the arc when the torch
is lifted at the end of the weld increased operator appeal. A CLOSER LOOK
