Rated cutting current
Air plasma
Cutting
Plasma cutting
2. Characteristics
LGK-40/63IGBT inverter air plasma cutting machine is the latest development cutter in 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) 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) The cutting current is very stable and it will not be influenced by grid voltage fluctuation.
5) There is over-voltage protection function.
6) Fast cutting speed, high production efficiency, and the speed is 2-5 times higher than
flame cutting speed.
7) Compressed air as cutting gas is low cost.
3. Usage
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.
◆ Safety and Attention

Please follow the notes for the safety of you and others.

It is forbidden to unfreeze the pipe line by cutting power or other usages except for
cutting.

The cutter casing should ground reliably. Please make sure the grounding bolts of
power ground reliably in case of electric shock.

Cutter is the equipment with high voltage. Please wear insulated protective shield
