Huayuan LGK 300 IGBT plasma arc cutting machine plasma power source
LGK-100/160/200/300IGBT inverter air plasma cutting machine is a new generated cutter of
our company. It has good characteristics as following:
1) This cutting machine adopts IGBT inverter technology which has high reliability and
efficiency. It is light weight.
2) Pre-set current function. Stepless adjustable cutting current, suitable for cutting various
thickness workpiece. To ensure cutting quality and save energy, low current is applied
to cut thin plate, and high current is applied to cut thick plate.
3) External and dynamic characteristics cutter are significantly better than leakage-reactance
typed cutter. High success rate in striking arc. Stable cutting current. Good arc stiffness.
Clean and smooth incision. Excellent technology performance.
4) It has the function of ascending current slowly, which can effectively extend the work
life of wearing parts and cutting torch.
5) Quite suitable for CNC automatic cutting and has all signal output which is required by
6) The cutting current is very stable and it will not be influenced by grid voltage
7) 100% duty cycle. It can work continuously under max current.
8) Have over/ under voltage and phase missing protection function.
It is suitable for cutting kinds of metal materials like low carbon steel, alloy steel and
non-ferrous metal and is widely applied in the manufacturing of boiler pressure container,
chemical container, industrial power station construction, metallurgy, aerospace industry,
automobiles, building an so on.
