Miller Big Blue 500X PRO Features
ArcReach® Technology
Equipped with exclusive ArcReach® technology, this feature allows process adjustments right from your weld cables, placing arc control beneficially at your fingertips. Ideal for both stick and solid wires, ArcReach ensures you’re no longer tied to the power source – a testament to the product’s superior convenience and reliability.
ArcReach Heater Compatibility
Assert control and efficiency in your preheating applications with the 400x Pro’s ArcReach Heater. Capable of reaching up to 600 degrees Fahrenheit (315°C), this system uses induction heating for quick, safe preheating. As part of the ArcReach technology platform, this heater is a beneficial accessory that provides soft tig arc starting.
Auto-Process Select™
Enhance your workflow with the 500x Pro’s Auto-Process Select™. This feature intuitively detects and switches to the correct process based on polarity and the connected ArcReach accessory, reducing the need to manually access the power source.
Advanced Features for the Professional Welder
The 500x Pro’s advanced features, including Adaptive Hot Start™, make starting stick electrodes a breeze. Benefit from infinite arc control in Stick and Wire modes, making arc control beneficial when fine-tuning tough-to-weld materials and out-of-position applications.
The Lift-Arc™ TIG feature minimises contamination risk during arc starting without requiring high frequency.
Control Panel Lock Out
There’s nothing to worry about accidental changes with its Control Panel Lock Out feature. It ensures that while an ArcReach accessory is in control, all process and amperage/voltage adjustments at the power source are securely locked out, preventing any unintentional alterations by non-operating personnel. This feature is your guarantee of absolute reliability and precision in every welding operation.
Dynamic DIG™
Expect a smoother, more consistent arc with Miller’s proprietary Dynamic DIG™. Compared to traditional DIG with preset short-clearing current, Dynamic DIG™ utilises a time-based algorithm to automatically adjust the required current to clear a short. This means you get an adaptable arc that can be customised to match the material, welder technique, application, and fit-up.
Fleet Compatibility
- Cross Platform Compatible: This ensures that ArcReach accessories used on engine-driven equipment are also compatible with select ArcReach-equipped XMT®, Dimension™, and PipeWorx 350 FieldPro™ power sources.
- Reverse Compatible: Reverse compatibility guarantees that ArcReach-equipped power sources work efficiently with non-ArcReach accessories, although full benefits are realised with the complete ArcReach system.
Heavy-Duty Low-Speed Deutz D2011 L03i Industrial Diesel Engine
More run hours mean more productivity with the heavy-duty, low-speed Deutz three cylinder oil cooled industrial diesel engine. Trusted in global industrial applications, engineered to provide hours of operation before major maintenance – backed by world-class service and support.
Increased Productivity & Safety
Complete your projects faster and safer with ArcReach. It significantly increases arc-on time and minimises the risk of trips, slips, and falls. With ArcReach, there’s less need to return to the welding power supply for process adjustments and arc amperage or voltage settings, boosting efficiency and safety.
Industrial USB Port
Conveniently keep your Miller Big Blue Pro 500x up-to-date and monitor its performance with the industrial USB port. You can download machine log files and perform software updates easily, offering valuable insights into diagnostics and machine statistics.
