DC welder capacity: up to 300A (35% duty cycle) / 250A (60% duty cycle)
Electromechanical regulation (steps): intuitive manual adjustment up to 36 steps for smooth and uniform results
Weldable electrodes: all types, including rutile, basic, and cellulosic
Thermal protection: included, with auto reset against overloads
Alternator type: Brushes | IP23 protection class
Available couplings: J609b (c25,4/35), B3/B9 (c30/38), IM B34, SAE
Made in Italy – robust, durable, and field-proven
Applications:
On-site welding for construction and civil engineering
Pipeline and medium-duty fabrication works
Agricultural and industrial maintenance
Auxiliary AC power generation in mobile and remote sites
