Features
- Run Longer and More Efficient – Weld longer with a class-leading 20 US gal. (75.7 L) fuel tank and integrated Auto-Stop/Start feature, designed to prevent excessive idling to help save on fuel costs, avoid unnecessary engine wear, and extend time between required maintenance.
- Field-Proven Diesel Engine – Powered by a 24.8 hp, naturally aspirated Kubota® diesel engine to provide extremely smooth and quiet operation while meeting EPA Tier 4 Final compliance.
- Trusted Reliability – Engineered tough to withstand harsh conditions and backed by trusted industry support and 3-year warranty.
- CrossLinc® Enabled – Allows communication through a standard weld cable to enable voltage or current control at the arc without a control cable to help improve safety, quality, and productivity with less trips to the power source and reduced jobsite clutter. Built-in True Voltage Technology™ (TVT) compensates for voltage drop to further improve operations.
- Full Job-Site Versatility – Offers up to 400 amps (IEC rated at 325 amps) of welding current to tackle numerous welding and carbon arc gouging applications. Includes six optimized CC and CV modes, plus advanced modes to support pulsed TIG, pulsed MIG, STT®, and mechanized equipment.
- All Day Auxiliary Power – Provides up to 11 kW of continuous three-phase power to run industrial tools such as plasma cutters, pumps, or inverter welders.
- Next-Gen Display – Bright, durable 7 in. digital user interface for unmatched machine control - Save and recall memories, receive maintenance reminders, and enable PIN authorization.
