Miller® Trailblazer® 302 Air Pak™ Welder with Air Cooler/Water Separator, GFCI and Electric Fuel Pump 907549003
The Miller® Trailblazer® 302 Air Pak™ with Air Cooler/Water Separator, GFCI and Electric Fuel Pump is a 300 amp gasoline engine driven welder/13,000 watt generator with an integrated rotary screw air compressor. It is a powerful all-in-one tool that is designed for repair and construction with unbeatable multiprocess weld quality. The Trailblazer Air Pak's integrated rotary screw air compressor produces 31 CFM of air at 100% duty cycle with a range of 80 to 160 PSIG; all with no storage tank. The air cooler with water separator separator comes already installed and reduces compressed air temperature, while removing up to 70 percent of moisture from the air supply. It is designed for use in ambient air temperatures above 32 degrees F (0 degrees C). The cooler/separator can be bypassed when air temperatures go below freezing.
The Trailblazer 302 Air Pak supplies a full 13,000 peak watts and 11,000 continuous watts of pure, four pole AC generator power. Auxiliary power is completely independent, which means you have full generator power even while welding. The Trailblazer Air Pak also comes standard with battery charge/crank assist for charging 12 volt or 24 volt batteries or for up to 450 amps of jump start power. Battery charge/cranks assist controls are conveniently located on the front panel. (Charging cables NOT included).
The model comes standard with two - 120 volt duplex receptacles with Ground Fault Circuit Interruption (GFCI) and an electric fuel pump. The electric fuel pump provides reliable starts and smooth engine function when operating above 5,000 feet above sea level.

Features
Installed Air Cooler/Water Separator cools air which turns vapor moisture into droplets and the separator removes the droplets
Removes 70 percent of the moisture from the air
Use for most applications including tools, blasters, plasma cutters and gouging
Effective when temperatures are above freezing (this is also when the most moisture is in the air). Below 32 degrees Fahrenheit (0 C) the separator can freeze. If this happens, bypass the cooler/separator system and continue air operations without drying it
Fully integrated inside of the Air Pak
Electric fuel pump provides reliable starts and smooth engine function when operating above 5,000 feet above sea level.
Two installed 120 volt GFCI duplex receptacles come standard for operation in areas where state or federal law requires Ground Fault Circuit Interruption.
Battery Charger/Jump Starter - Provides selectable 12 or 24 volt battery charging capability. Provides up to 450 amps of battery jump-starting capability.
Three take-charge tools in one - The all-in-one tool that delivers multiprocess output for welding, plasma cutting, gouging, and air tools.
- Accu-Rated™ 13,000 watts of usable peak generator power
- Professional welding performance in all processes with the best welding arc in its class.
- Rotary-screw compressor delivers 31 CFM of air at 100% duty cycle
Requires Half the Space - Takes only half the bed space of a separate engine-driven air compressor and welder, freeing up 50% more room on your truck for equipment and supplies.
Better Truck Payload - Offers up to 25% less axle weight for payload advantage.
Strongest Combined Generator/Compressor Power - Delivers an industry-leading 13,000 watts of peak generator power independent of weld settings - enough to power a Spectrum® 875 plasma cutter, and provide air for plasma cutting at the same time. (Rated 5/8" mild steel)
Easy to Service - Side and top access doors make it fast and easy to reach engine and air compressor compartments. Digital maintenance meters automatically track hours, service schedules.
Lower Fuel Consumption and Emissions - Air compressor, welder and generator are all run with one engine, reducing emissions and reducing fuel consumption up to 50%.
Ultra-Reliable Rotary-Screw Compressor -

Deliverable Air, On Demand - Produces 100% deliverable air at 80 to 160 PSIG when you need it: no more down time waiting for an external tank to fill. Airflow can be selected depending on tool requirements.
Front Panel Air Pressure Adjustment -
- Simple to dial in the correct air pressure for specific applications (80-160 PSI)
- Increases engine power for more gouging and plasma cutting capabilities
