Performance

 

◎     Advanced in design; soft switch inverting technology; take the imported IGBT and micro-crystalline magnetic core as focus parts.

◎     Take the compressed air as the cutting air source to ensure a high economic efficiency.

◎     Curve cutting can be carried out on metal sheet with different thickness freely.

◎     Stable cutting electric arc; quick speed; smooth cutting edge; little deformation and hanging residue

◎     Contact striking arc model

 

For the adaptable to automatic cutting cnc machine

 

◎     Orignal framing signal: offering the orignal framing signal to system when cutting torch touch the workpiece

◎     Current with signal or not: offering the current signal to system after the cutting source power on.

◎     Signal of arc voltage heightening: offering the arc voltage signal to system through the cutting process. The system would adjust automatically the cutting height basing on the arc voltage.

◎     Short circuit protection signal: cutting power source automatically to protect cutting torch when there is short circuit for the cutting torch and workpiece.

 

Functions

 

◎     Widely used in such fields as chemical machinery, pressure vessel, decoration industry, kitchen equipments, shipping, vehicle, farming machinery industry. It can cut stainless steel, carbon steel, alloy steel, aluminum, copper, nickel and titanium.
