Description

Applicable industry: Pressure vessel, petroleum pipeline, boiler manufacturing, mechanical production, electronic/chemical/oil construction

1. Powerful ability to resist grid fluctuation: The welding output parameter will not be affected by 土15% voltage fluctuation, what's more, it can be matched with the field operation of motor.

2. The lengthening-line current has not been attenuated: The welding line can be lengthened to 50m, then, the welding voltage will be automatically compensated without attenuated current.

3. Digital displayer meter: The panel display meter can show the preset current and input voltage.

4. With the thrust modulation function: Effortless arcing, fine globular transfer, small spatter, non-adhesive tape and satisfactory weld appearance.

High load persistency rate: Apply the high-performance components and three air shaft technology.

6. The machine has high self-protection grade: Employ the humanized cant design appearance and four-corner protective design to significantly enhance the product protective degree and make the appearance be beautiful and elegant.
