PERFORMANCE

Arc Performance

•Pure DC generator welding arc is preferredby pipelinersand contractorsfor precise control of the arc in demanding code applications.

•All copper windings enhance arc stability for that really smooth high performancearc.

•Custom Arc® — Kubota® model includes 150 RPM High Idle (OCV) AdjustmentRange — enhanced fine tuning for performance on pipe.

•300 amps @ 60% duty cycle. Welds with up to 7/32" (5.6 mm) Fleetweld® 5P+ cellulosicand Excalibur® low hydrogenelectrode.

•Arc Gouging with up to 3/16" carbons.

GeneratorPerformance

•3,000 total watts of AC power from a 115V or 230V duplex receptaclefor power tools and lights.

•Circuit breaker protection.115V AC 20 amp output will operate up to a 9" grinder.

•Weather-protectedreceptaclecovers.

•GFCI (Ground Fault Circuit Interrupter)115V AC receptaclesare standardfor added safety.

Use the High Idle (OCV) engine speed adjustmentdial 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,especiallyon 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.

(Availableon Kubota® model only.)

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

•OptionalWire Feed Module for CV-wirewelding.Increasespro- ductivityand reducesweldingcosts. Recommendedwire feeders includeLN-25 PRO or LN-15 Across-the-Arcmodels. Module has 14-pin connectorfor Lincolnwire feedersthat use a controlcable with 115V AC input: LN-25, LN-23P,LN-7, LN-7 GMA and LN-8. Built-incontactorfor “cold-tip”electrode.(When CV wire welding with optionalWire Feed Module,idler may need to be set to “high” positionfor low currentprocesses.)

•OptionalK2464-1remotecontrolkit for stick and wire welding.For machinesthat have the Wire Feed Module installed.Make output adjustmentsup to 100 ft. from the machine.

“After our Local 375 school participatedin the evaluationof Lincoln Electric’s Classic® 300D, the company generously donated the machine to our facility.As an apprenticeprogram for the Plumbers

&PipefittersUnion, we are grateful for the opportunityto use such a high quality piece of equipment. We especially benefit from the Pure DC generator because it produces a superior arc. This characteristicis ideal in pipe welding, therefore, the Classic® 300D allows us to provide our students with exemplary models for their education.”
