APPLICATION
The screen protects the plasmatron nozzle from forming a double arc and burning through accidental contact with a metal workpiece. The tool directs a gas jet to cool the nozzle.
The screen is used in manual and automated cutting equipment. Plasma cutting of metal is used in mechanical engineering and shipbuilding, oil and gas industry, production of metal structures
The screens are suitable for plasma cutting equipment of the following types:
- Mechanized and manual
- Vertical and oblique cutting
- Low-carbon and stainless steel, aluminum
- Marking
The quality of the plasma cutting screen affects the service life, cutting quality, and overall performance of the equipment.
The plasma cutter screen is subject to wear during operation. The main reasons are burning the sheet too close to the plasma cutter and exposure of the screen surface to melt drops.
Follow the recommendations in the operation manual and monitor the nozzle condition. If signs of degradation are detected, replace the screen.
The range includes all the necessary plasma tools: electrodes, nozzles, bushings, screens, protective caps, swirlers.
FEATURES
Screens for plasma cutting equipment are made of standard quality. To extend the service life, components must be selected depending on the operating current and the equipment characteristics.
The screen surface is smooth and has no roughness. Nanocoating on the screen reduces the sticking of molten metal splashes and clogging of openings.
The screen is easily mounted with a threaded connection.
Operation requires regular inspection and replacement in case of color change or degradation caused by melt.
STRUCTURE AND OPERATION
The cutter of plasma cutting device consists of an electrode unit and a nozzle separated by an insulating bushing. The screen protects the plasmatron interior from melt drops.
The electrode consists of two parts: the housing and the insert. The housing serves as a current conductor and heat sink. The insert is made of a refractory metal (tungsten/hafnium).
An electric arc is ignited between the electrode insert (cathode) and the nozzle (anode). The bushing is used for connecting current-carrying parts and serves as an insulator.
Air is supplied to the inner chamber of the nozzle under pressure. Once in the electric arc, the gas turns into plasma and is blown out by a new portion of air through the nozzle opening.
The nozzle is cooled by air flow. High-power plasma cutting tools use liquid cooling, which provides a better cutting quality.
The plasma jet melts the section of metal above which the plasmatron head is located. When it moves along the trajectory set by the program or operator, the melt is blown out by the airflow and a cut remains in the metal.
The plasma cutting tool can work with 30-800A current sources
