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. 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 pro- ductivity 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. “After our Local 375 school participated in the evaluation of Lincoln Electric’s Classic® 300D, the company generously donated the 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...
