Inverter Plasma Cutting Machine

The Inverter Plasma Cutting Machine features an Untouch startup system that uses HF to control smooth arc strikes.
It supports continuous adjustment of the cutting current.
Its fast arc-hit design features high-quality narrow cuts and excellent travel speeds.

Product Details

Description:

There are large-scale applications in custom car workshops as well as in car manufacturers' custom chassis and body manufacturing. Construction companies use plasma cutting machines for large-scale engineering to cut and manufacture large beams and sheet metal parts. When the customer is locked outside the door, the unlocking master can use a plasma cutter to drill holes in the safe area.

Principle

Plasma is a gas that is heated to a very high temperature and is highly ionized. It transfers the arc power to the workpiece. High heat causes the workpiece to melt and be blown off, forming a working state of plasma arc cutting.

After the compressed air enters the torch, two channels are distributed from the air chamber to form a plasma gas and an auxiliary gas. The plasma gas arc acts to melt the metal, while the auxiliary gas cools the various components of the torch and blows away the molten metal.

The cutting power supply consists of two parts: the main circuit and the control circuit. The electrical principle block diagram is shown in the figure:

The main circuit consists of a contactor, a three-phase power transformer with high leakage resistance, a three-phase bridge rectifier, a high frequency arc ignition coil and protection components. The high-leakage resistance is caused by the steep external power characteristics. The control circuit completes the entire cutting process through the push button switch on the torch:

Pre-ventilation - main circuit power supply - high frequency arcing - cutting process - arc - stop.

The power supply of the main circuit is controlled by the contactor; the short-circuit of the gas is controlled by the solenoid valve; the control circuit controls the high-frequency oscillator to ignite the arc, and stops the high frequency after the arc is established.
