Excellent for Pipelines, Construction
and Maintenance
The Classic®300D is popular throughout North America for
pipeline, construction and maintenance welding. It features
proven, simple and rugged construction, along with Lincoln’s
well-known pure DC generator design for excellent performance
on pipe. The Classic
water-cooled industrial diesel engines from Perkins
The Classic
®
run grinders and lights. CV wire welding can be added with the
optional Wire Feed Module. Also choose from several packages
available with trailers.
®
300D is offered with a choice of 4-cylinder,
®
and Kubota®!
300D includes 3,000 watts of AC generator power to

Arc Performance
• Pure DC generator welding arc is preferred by pipeliners and
contractors for precise control of the arc in demanding code
applications.
• All copper windings enhance arc stability for that really smooth
high performance arc.
• Custom Arc®— Kubota®model includes 150 RPM High Idle
(OCV) Adjustment Range — enhanced fine tuning for performance
on pipe.
• 300 amps @ 60% duty cycle. Welds with up to 7/32" (5.6 mm)
Fleetweld®5P+ cellulosic and Excalibur®low hydrogen electrode.
• Arc Gouging with up to 3/16" carbons.
Generator Performance
• 3,000 total watts of AC power from a 115V or 230V duplex
receptacle for power tools and lights.
• Circuit breaker protection. 115V AC 20 amp output will operate
up to a 9" grinder.
• Weather-protected receptacle covers.
• GFCI (Ground Fault Circuit Interrupter) 115V AC receptacles are
standard for added safety.
Use the High Idle (OCV) engine speed adjustment dial to change the
heat input to the arc:
• Set the arc in the machine’s “sweet spot”.
• Dial in a softer or more digging arc.
• Reduce root pass internal undercut, especially on X60 and X70
pipe.
• Stack iron faster with low heat and a clear puddle on fill passes.
• Avoid arc breaks. Avoid slag that crowds the arc.
• Control fusion on the cap pass with good puddle size and clarity.
(Available on Kubota
®
model only.)
FEATURES
• Choice of two industrial 4-cylinder, smooth-running, water-cooled
diesel engines:
– Perkins®404D-22
98.1 dB sound power (Lwa) at rated load.
– Kubota®V2403M
99.9 dB sound power (Lwa) at rated load.
• Gauges indicate oil pressure, engine temperature and battery
charging amps.
• Engine hour meter to track scheduled maintenance.
• 15 gallons (57 ltrs) fuel capacity to work an extended day
without refueling.
• Oil drain valve and tube are standard.
• Compact size for installation on truck beds.
• Local/Remote switch and recptacle are factory installed for easy
connection of the remote control.
“After our Local 375 school participated in the evaluation of Lincoln
Electric’s Classic
machine to our facility. As an apprentice program for the Plumbers
& Pipefitters Union, we are grateful for the opportunity to use such
a high quality piece of equipment. We especially benefit from the
Pure DC generator because it produces a superior arc. This
characteristic is ideal in pipe welding, therefore, the Classic®300D
allows us to provide our students with exemplary models for their
education.”

Stick Welding
• Optional K924-5 Remote Control Kit for stick welding (for
Classic
®
300D codes 10911 and higher). Includes Remote Box
and 100 ft. cable. Make fine current adjustments up to 100 ft.
from the machine.
Wire Welding
• Optional Wire Feed Module for CV-wire welding. Increases productivity and reduces welding costs. Recommended wire feeders
include LN-25 PRO or LN-15 Across-the-Arc models. Module has
14-pin connector for Lincoln wire feeders that use a control cable
with 115V AC input: LN-25, LN-23P, LN-7, LN-7 GMA and LN-8.
Built-in contactor for “cold-tip” electrode. (When CV wire welding
with optional Wire Feed Module, idler may need to be set to “high”
position for low current processes.)
• Optional K2464-1 remote control kit for stick and wire welding. For
machines that have the Wire Feed Module installed. Make output
adjustments up to 100 ft. from the machine.
