Description
Specially designed for heavy industrial applications, the YUVA 400PR DC Inverter MMA Welder (PR Series) features a robust 70% duty cycle and advanced high-efficiency inverter technology with a 30kHz working frequency, ensuring energy savings and environmental protection. It offers reliable performance with under-voltage, over-voltage, and over-current protection, and adapts to a wide input voltage range from 280V to 560V in three-phase systems. With a stable arc CC feature, modular functional units, and new-generation IGBT modules, the machine provides high stability and reliability even when using long welding cables up to 500 meters or unstable generator power outdoors. Suitable for acid, basic, and high-strength electrodes, it includes smart fan technology and built-in VRD protection with an on/off switch to meet CE standards, making it a powerful choice for demanding welding environments.
