LGK-160 plasma cutter is mainly used to planning and chipping of carbon steel, stainless steel and metal materials such as aluminum, aluminum alloys, copper and copper alloys.

Inverter welding machine is a new type of welding power supply. The working principle is as follows: First, power frequency voltage of AC network is converted to DC voltage after being rectified and filtered by the rectifier. Then, after the interchangeable effect of high-power switch electronic components like MOSFET or IGBT, the DC voltage is inverted to AC voltage with frequency ranging from tens of kHz to hundreds kHz. Subsequently, the step-down transformer lowers the voltage to tens of volts which is suitable for welding.
