Miller Blue® 500 X Diesel Engine-Driven Welder/AC Generator

Availability : in stock

Heavy-duty low-speed industrial diesel engine is designed to operate over 10,000 hours before the first basic overhaul. Backed by worldwide support and service.
Meter maintenance displays
• Fuel gauge
• Hour meter function
• Oil change interval
• High coolant temperature and low oil pressure shutdowns
• Low fuel shutdown — engine shuts down before system runs out of fuel, making restarts easy.
Arc-Drive™ makes welding easy. Automatically enhances stick welding, especially on pipe, by focusing the arc and preventing theelectrode from going out.
Miller engine drives are tested to perform in high-temperature climates, even at the highest recorded temperature on earth — 56.7°C*. They are designed to excel in extreme heat by optimizing engine cooling, reducing harmful environmental effects. In addition, the machines are equipped with thermal overload protection which prevents machine damage if the duty cycle is exceeded, the airflow is blocked, or if the thermostat detects overheating
Hot Start™ provides positive stick electrode starts making it easy to start all types of electrodes and it also works great for bead tie-ins.
Three-phase rotating field generator efficiently produces smooth DC weld output using 20 to 30 percent less fuel than a rotating armature-type DC generator.
Enclosed robust case design protects internal components from impact and allows air flow to cool and prolong the life of the engine. Also reduces sound levels.
Quick and easy maintenance with single-side access to oil level check, oil fill, oil filter, fuel filter and air cleaner.
Remote toolless oil drain allows oil to be drained without getting under the engine and reduces the chance of oil spillage.
HD powder coat with zinc-rich primer protects sheet metal from rust and corrosion.
GFCI receptacle as required on most jobsites to protect operators from electrical hazards.
CSA, IEC and NEMA compliant for welders. Degree of protection provided by enclosure IP23.
