Miller Big Blue® 600 Air Pak Welder/Generator with ArcReach #907750

This all-in-one field-based welder/generator from Miller® eliminates the need for an auxiliary air compressor. With single-operator power for welding and carbon arc gouging, it's ideal for critical repairs and maintenance work. The generator produces 27,000 peak watts of power when using 3-Phase power or 15,000 watts on single-phase, and the built-in Ingersoll Rand screw-type air compressor is perfect for gouging and running pneumatic tools.

The Big Blue 600 will keep your crew productive with reliable welding equipment and time-saving innovations like ArcReach, which makes it possible to make parameter adjustments right where they're welding instead of having to walk back to the machine. And with the cleanest, greenest diesel power available, the T4F-compliant Deutz industrial diesel engine will have everyone breathing a little easier.

Experience the power of True Blue® for yourself, and you'll understand why so many pros choose Miller.
