1.5 Functions and characteristics of the cutting machine

Features

The machine adopts advanced inverter technology. High inverter frequency of 20 KHz greatly
reduces the volume and weight of the cutter.

Great reduction in magnetic and resistance loss obviously enhances the cutting efficiency
and energy saving effect.

Closed loop feedback control, stable output cutting current, workable under mains voltage
fluctuation within ±15%.

Non-contact ignition with pilot arc, excellent arc ignition, can cut rusty and painted metals
conveniently.

Excellent dynamic characteristics, high arc stiffness, smooth cutting surface, high cutting
performance.

Current upslope function is available when arc is ignited to carry out cutting, which can
reduce the arc ignition impact. Beside, the constant pilot arc technology can effectively
prolong the lifespan of the electrode and nozzle of the cutting torch.

The cutting current can be accurately preset and stepless adjustment can be achieved
through the preset current function. Thus, the machine is can be used to cut workpiece with
different thickness. Low current is used when cutting thin plate and high current is used
when cutting thick plate to ensure cutting quality and save energy.

With protection function of over/under-voltage, overheating and low gas pressure inside
the machine; gas-check and 2T/4T function available; arc establishing signal and
output signal optional; convenient to connect all kinds of CNC machine tools.

Adopting main components of world's top brands, with high reliability.
Application

Economic and practical by adopting compressed air as the plasma gas source. The plasma
cutter has a wide range of use, especially for cutting metal plates of carbon steel, alloy steel,
stainless steel, galvanized steel, copper and aluminum, etc.

It can be widely in various industries involving metal cutting such as boiler and pressure
vessel manufacturing, chemical container manufacturing, power plant installation and
construction industry, metallurgy, chemical engineering, aerospace, automobile and
engineering vehicles manufacturing and construction, etc.

1.6 System characteristics

1) Duty cycle
Rated duty cycle refers to the percentage of the normal work time of the machine under rated
maximum current holding in the period when taking 10 minutes as a period and the
environmenttemperature is 40℃.The rated duty cycle of this machine is 60%. That is to say,
under the working current of 160A, the plasma arc can work for 6 minutes continuously in a
10-minute period without leading to overheating of the machine. Using the cutting machine
arc voltage
