Product Description
Based on digital waveform control technology to achieve accurate current and voltage output, mixed gas and controlled pulse current to achieve welding ultra-low splash
DSP core device is used to quickly calculate and control welding current waveform, which is specially built for carbon steel and stainless steel welding
Segmented control of current and voltage waveform can cover the welding stability of small, medium and large current ranges
Rated load duration 100% (40ºC) technical index, suitable for high strength, harsh environment conditions
With a unified function, novice can also easily control
With the function of storage and call, it has 20 channels and saves 20 groups of parameters
It has the functions of overheat, overvoltage, undervoltage, phase deficiency and overcurrent protection
It has CAN communication interface and other extended communication interface to meet the matching use of robots and other automatic welding equipment
Product application
Ideal for all position welding of carbon steel and stainless steel solid wire
Mainly used in Bridges, ships, construction machinery, steel structures, large components and other high-quality weld requirements
