FAETURE& FUNCTION
●IGBT inverter technology. Processes Stick/ MIG.
20KHz inverter frequency, small ,light ,easy to carry wherever you want.
●Significantly reduce the copper loss and core loss, obviously improved the
efficiency of the machine, energy-saving effect is remarkable.
●The switching frequency in the audio, virtually eliminates the noise pollution.
●The control way of leading.
●Closedloop feedback control, stable output voltage, reduces power grid and
voltage (± 15%).
●Welding voltage and welding current can be adjusted continuously, to achieve
accurate matching, excellent welding characteristics.
●The unique characteristics of control circuit for welding, welding arc stability,
welding spatter, forming beautiful, high welding efficiency.
●With post weld ball function, eliminate the wire end droplet beads,
supplemented by high noload, slow wire feed function, improve the
success rate of an arc.
●For the protection of carbon dioxide gas (CO2) or mixed gas (MAG) welding.
●The design of functional.
●The wire feeding part and is separated from the main part of wider,
the welding operation.
●The preset current manual arc welding, gas metal arc welding preset voltage,
convenient operation.
●Spot / long welding, spot welding sheet metal is not easy to weld penetration.
