The Power of Blue.
	®
					Weld meters now standard.
The professional welder’s choice with higher outputs is					With a compact and lightweight

designed to deliver the best arc performance with enough weld power to dominate larger diameter flux cored wires and air carbon arc gouging thru 1/4 in carbons.

Toolless top and side engine access allows easy and faster maintenance with little clearance space needed.

Toolless remote oil drain is standard.

Standard 14-pin receptacle easily connects feeders or remote controls for enhanced process operation.

12,000 watts of generator power is regulated to provide constant, strong power and very good motor starting characteristics. Power is independent of weld control settings so that the correct voltage is available at all times.

Strong 120/240 V power while welding to run tools and inverter welders. See page 3 of literature.

Automatic Start at Idle™ idles engine immediately when started, extending engine life and reducing

fuel consumption and noise.

Weld at Idle™ — lock in idle and weld in

DC up to 180 A.

Welder/generator is warranted for 3 years, parts and labor.

Engine is warranted separately by the engine manufacturer.

design at only 998 lb, a smaller truck can be used, and related transportation costs will be reduced. Low height allows the driver to see over the machine when mounted on a truck bed and the machine fits sideways in a standard pickup.

Even better weld performance with an arc that dominates the competition. In Stick mode, you get a smooth E7018 and a great E6010 arc with Arc-Drive and Hot Start™ standard. Great MIG/FCAW arc and machine idles with feeders hooked up. More stable AC TIG and excellent starts in DC scratch start TIG.

26 HP, 3-cylinder Kubota diesel engine with its durable, proven liquid-cooled design is the world standard for small diesel engines. Engine shutdowns standard.

Cold weather starting aids such as standard glow plugs and block heater ensure good starts in cold weather.

Automatic idle in all processes, including MIG/FCAW with feeders to save fuel and reduce noise.

Performance Data

FUEL CONSUMPTION DATA

•13-gallon fuel capacity.

•Welding at 150 A at 40% duty cycle, uses only

.61 gallon per hour — over 20 hours of operation.

Performance Data (continued)

All Trailblazers have 2 generators —

a 4-pole, 3-phase weld generator and a strong power generator.

TRAILBLAZER ADVANTAGE: No interaction between grinders, power tools, etc. and the welding arc. Generator power is also independent of weld control settings.

	Rotor				Stator

POWER IS IN THE NUMBERS

•Tested and rated at higher temperatures, 104˚ F (40˚ C), to ensure consistent operation in all climates.

•Patented generator control technology matches the generator’s output to engine horsepower providing maximum efficiency and more weld output.

•The generator is voltage regulated to provide strong power while keeping the voltage 120/240 volts. This increases tool/motor performance and tool/motor life.
