Features
■ Adopt the soft switch technology, high efficiency, low power consumption
■ Automatic protection from overcurrent, overheat, over/under voltage
■ Support digital display and presetting of current and voltage, wide adjustment range of voltage
■ Particular function of automatically removing melting-ball from the end of the welding wire
■ Adopt the closed-loop system to control arc and waveform control system to adjust the arc force
■ Suitable for low carbon steel and low alloy carbon with solid/flux-cored welding wires of different specifications
■ Widely used in such areas as automobile, shipbuilding, bridge, petrol chemistry and construction, and so on
■ Wire feeder is driven by four wheels, big power, and feeding wire stably
■ Wide range of supply voltage, as wide as ±20%
■ C type is the one with duty cycle of 100%
■ S type support MAG/MMA welding
