The Miller's Diesel engine driven autonome welders for the most demanding weld applications, Stick (SMAW), Flux Cored (FCAW), Lift-Arc DC TIG (GTAW), air Carbon Arc (CAC-A)electrode .Ideal for rental or fleet managers who value
reliability, ease of service, and long life at an economical price.
Heavy-Duty Low-Speed Kubota V1505 Industrial Diesel Engine
Used in industrial applications around the world, the V1505 is designed to run 10,000 hours before major overhaul. Backed by worldwide support and service.
Improves work site safety and communication.
Digital Meters with SunVision™
Enables welding parameters to be viewed with greater clarity at virtually any angle. Meters can be seen clearly even in direct sunlight.
Industrial USB Port
Quickly upload the latest software and download machine log files to retrieve in-depth information such as diagnostics and machine statistics.
Auto Remote Sense™ (ARS)
Detects if a remote control is plugged into the 14-pin receptacle and eliminates confusion of a remote/panel switch.
Requires no elaborate procedure - just select process and weld!
HD Powder Coat
All painted sheet metal is pretreated with a zinc-rich primer to provide extra protection against rust & corrosion (comparable to stainless steel).
Advanced Features for the Professional Welder
- Adaptive Hot Start™ makes starting stick electrodes easy without creating an inclusion.
- Infinite arc control available in the Stick and Wire modes for easier fine tuning of tough-to-weld materials and out-of-position applications.
- Lift-Arc™ TIG provides arc starting that minimizes the risk of electrode/work contamination without the need for high frequency.
Low OCV Stick (VRD)
When activated, reduces the open-circuit voltage to 15 volts when the power source is not in use, increasing operator safety without compromising arc starts.
Other Standard Features
Output contactor control, automatic idle, thermal overload protection, and 120-volt engine block heater.
Air Carbon Arc Cutting and Gouging (CAC-A)
