Miller 907732011 Big Blue® 400X Pro Engine Driven Generator for Welding
Designed with the professional in mind, the Big Blue® 400X Pro is the best for ease of use, reliability and fuel economy, the Big Blue 400X Pro has been designed with the professional welder in mind. This machine has been constructed to last in the harshest industrial environments and workshops and provides a new standard in productivity and weld quality in arc performances.
SunVision™ technology enables welding parameters to be seen with superior clarity than analogue meters from virtually any angle. This feature can also be viewed in direct sunlight. The Big Blue 400X Pro possesses 'easy to set up' controls that do not require long-winded instructions and explanations.
Includes an industrial USB port, which can upload the latest Miller-branded software and download machine log files that contain detailed information such as diagnostics and machine statistics.
ArcReach Technology
The ArcReach system allows the welder to change weld settings from an ArcReach feeder or remote without travelling to the power supply. This revolutionary technology uses the existing welding cable to communicate welding control information between the feeder or remote and the power source. Therefore, the need for controls and their associated problems and costs is eliminated.
