The Frontier® 400X is an advanced, next-generation engine-driven welder/generator offering best-in-class arc performance, coupled with the latest welding technology innovation for maximum versatility and productivity on demanding construction and pipeline job sites. This professional machine's comprehensive multi-process welding capability provides optimized CC (Constant Current) and CV (Constant Voltage) welding modes, plus specialized advanced modes to support mechanized welding equipment and advanced GMAW applications including revolutionary STT® (Surface Tension Transfer®) and pulse welding processes. The Frontier® 400X features an industry-first, next-generation 7-inch digital display with enhanced operator-focused features such as save and recall weld parameter memories, proactive maintenance reminders, and optional PIN user authorization for equipment security. Additional advanced features include intelligent Auto-Stop/Start technology to help reduce unnecessary engine idling, save on fuel costs, and avoid excessive wear on the diesel engine, along with CrossLinc® Technology which allows the remote adjustment of machine welding output directly at the arc to promote productivity, job site safety, and overall weld quality. Experience the latest in professional welding innovation!
- Complete Job-Site Process Versatility - Delivers up to 400 amps (IEC rated at 325 amps) of powerful welding current to tackle numerous welding processes and carbon arc gouging applications. Includes six optimized CC and CV welding modes, plus advanced specialized modes to support pulsed TIG, pulsed MIG, STT® (Surface Tension Transfer®), and mechanized welding equipment for maximum application flexibility
- All-Day Auxiliary Power Generation - Provides up to 11 kW of continuous three-phase auxiliary power to simultaneously run industrial tools and equipment such as plasma cutters, hydraulic pumps, grinders, or inverter welders directly on the construction job site without requiring separate generators
- Next-Generation Digital Display - Bright, durable 7-inch digital user interface provides unmatched machine control and visibility - Save and recall weld parameter memories for consistent results, receive proactive maintenance reminders to maximize uptime, and enable optional PIN authorization for equipment security and user accountability
- CrossLinc® Remote Control Technology - Industry-leading CrossLinc® technology allows digital communication through a standard weld cable to enable voltage or current control directly at the arc without requiring additional control cables, helping to improve job site safety, weld quality, and operator productivity with fewer trips to the power source and significantly reduced job site clutter. Built-in True Voltage Technology™ (TVT) automatically compensates for voltage drop over long cable distances to further improve welding operations and weld quality
- Extended Runtime and Fuel Efficiency - Weld longer with a class-leading large-capacity 20 US gallon (75.7 L) fuel tank and integrated intelligent Auto-Stop/Start feature, specifically designed to prevent excessive unnecessary engine idling to help save on fuel costs, avoid unnecessary engine wear, and extend time intervals between required maintenance services
