1.adopt  IGBT inverting technique circuit

 2.compensation function to voltage fluctuation,with strong voltage fluctuation resistant ability

3.high efficiency and samll no-load loss,save more than 40% power compared with traditional welder.

4.small volume and light weight which is convenient to use in high working places.

5.arc-striking is easy ,small splash,low noise ,stable welding arc ,and perfevt welding seam .

6.with inner installing protective circuit of over-heat,over-current,under-voltage and over-vlotage .it is safe and reliable to use

7.parameter of arc beginning and arc ending is adjustable easily,suitable for any thickness metals welding ,and easy to start and end arc under discontinous welding.

8.length of welding cable is adjustable for different distance of earth led and section.
