BIG BLUE 500 X

Designed for fleet owners that demand the ultimate in reliability and performance.

ARC-DRIVE Makes welding easy. Automatically enhances Stick welding, especially on pipe, by focusing the arc and preventing the electrode from going out.

Remote toolless oil drain allows oil to be drained without getting under the engine and reduces the chance of oil spillage.

Industrial-grade, sealed marine ignition switch starter interlock prevents the starter from engaging while the engine is running. Protects ring gear and starter from abuse.

The Big Blue 500 X is ideal for pipline contractors, rental or fleet managers who value reliability, ease of service, and long life at an economical price.

4-cylinder industrial liquid-cooled engine designed, built and proven to operate over 10,000 hours before the first basic overhaul.

Automatic engine shutdown protects engine if low oil pressure or high coolant temperature occurs.

Engine gauges are standard Oil pressure and coolant temperature gauges provide visual engine vitals.

Three-phase rotating field generator efficiently produces smooth DC weld output using 20-30% less fuel than a rotating armature-type DC generator.

Hot Start™ provides positive Stick electrode starts to make it easy to start all types of electrodes, and works great for bead tie-ins.
