Lincoln Ranger 330MPX EFI Welder/Generator W/Gfci (K4779-1)

The Lincoln Ranger 330MPX packs 330 amps of DC output into a footprint Lincoln says is 20% smaller and 25% lighter than other engine-driven welders in its class, with a digital push-and-turn control panel instead of analog dials. GFCI protection on this configuration adds a layer of shock protection at the receptacles, and the EFI-equipped Kohler engine is built for more reliable starts at altitude or in cold weather.

Technology aimed at less downtime

• ArcFX Technology shows instant graphical feedback on how a setting change affects the weld
• Chopper Technology for easy starts, a smooth arc, and low spatter
• CrossLinc remote voltage control over the single weld cable already in use
• A spool gun, K3569-2, that connects directly with no separate control box, which Lincoln calls a first for its class
• Supervisor and operator passcode locks for settings and weld mode
• Indicators flag service needs for the air filter, spark plug, brushes, and both oil and fuel filters

Lincoln rates the duty cycle at 100% at 330A DC CC and 100% at 312A DC CV, with arc gouging up to a 3/64″ carbon electrode. A 6-pin connector covers remote control or a foot/hand Amptrol, and the front panels open to protect the receptacles and weld lead connections when the machine is parked between jobs. Lincoln also measured it at 74.7 decibels at full load, up to 60% quieter than competing machines in its class by their own figures.

Engine and generator numbers

A Kohler OHV Command CH740 gas engine, two-cylinder, air-cooled, makes 25 HP at 3,600 RPM with electric start, drawing from an 11-gallon fuel tank and 2.0 quarts of oil. Generator output peaks at 11,500 watts with 10,000 watts continuous. The whole unit weighs 446 lbs, and Lincoln backs it with a manufacturer's warranty.

Does it need a separate control box for spool gun work? No, the K3569-2 spool gun connects directly with no additional control box or accessories. What protects the connections when not in use? Open/close front panels cover the receptacles and weld lead connections.
