Big Blue® 800 Duo Air Pak
Miller Electric Mfg. LLC.
The most powerful T4F diesel welder/generator/air compressor in the industry. The Big Blue 800 Duo Air Pak offers robust output for welding and power generation, and is ideal for dual-operator applications on labor intensive jobsites, or jobsites with limited space.
Features & Benefits
Multi-arc Welding
One dependable engine—two independent arcs with up to 400 amps each. Or plug in additional inverters for a true multioperator work platform! Example: Two additional XMTs equals four operators, up to 200 amps each.
Electronic Engine Display
Simultaneously displays fuel level, engine hours, coolant temperature, oil pressure, battery volts, and engine RPM. Also tracks oil change intervals and displays engine diagnostics for quick and easy servicing.
Air Compressor - Ingersoll Rand
Ultra-reliable industrial rotary screw air compressor. 30,000-hour life expectancy. Independent on/off control for applications not requiring compressed air — allows greater fuel savings and longer compressor service intervals.
Low OCV Stick (VRD)
Reduces the open-circuit voltage to 15 volts when the welding power source is not in use, increasing operator safety without compromising arc starts. Remote Oil Drain Prevents spills and makes servicing engine and compressor oil easy.
More Power & Increased Efficiency
33 percent increase in rated output equals 800 amps of weld power and 27,000 watts of generator power. More arcs and better fuel economy equal increased profits for your business.
Heavy-Duty Low-Speed T4F and T4i Industrial Diesel Engines
The cleanest, greenest diesel power available. Utilizes Diesel Oxidation Catalyst (DOC) technology to keep the air clean with NO exhaust after-treatment maintenance.
The Vault
The vault allows for the ultimate control board reliability in CC/CV models. Hardened solid-state control technology, housed in a sealed vault.
Infinite Arc Control
Allows the arc characteristics to be changed for specific applications in Stick, MIG and FCAW Thermal Overload Protection Prevents machine damage if the duty cycle is exceeded or airflow is blocked.
