- 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
■ A voltage fluctuation of ±20% is allowable
■ Small size, light weight
■ Support frequent welding, little spatter, high efficiency in melting metals
■ Support MIG welding, MMA welding
