The machine supports multiple welding processes, including MIG/MAG, MMA, TIG Lift, and spot welding, making it suitable for a wide range of welding tasks. It delivers a maximum welding current of 400 A, with a duty cycle of 400 A at 60% and 350 A at 100%, ensuring stable performance during continuous operation.

The Evolution SP4-E operates on three-phase power (3 × 400 V, 50/60 Hz) and features an open-circuit voltage of approximately 63 V. The inverter technology provides precise arc control, smooth ignition, and reduced spatter, while advanced functions such as Hot Start, Arc Force, Anti-Stick, Soft Start, Burn-Back, and programmable welding parameters enhance usability and welding quality.

The machine is rated IP23S, making it suitable for demanding workshop environments. With an overall weight of approximately 115 kg, the SP4-E offers a solid industrial build while remaining mobile within the workshop. Cooling is provided by an efficient air system, with the option to use a water-cooled torch when required.

The Sincosald Evolution SP4-E is an ideal solution for metal fabrication, repair workshops, and industrial production environments that require a powerful and versatile welding power source.
