APPLICATION
The bushing is designed for assembling the electrode and nozzle into a single tool. The bushing insulation material separates the cathode and anode.
The consumable tool is used in manual devices and 2D/3D machines. Plasma cutting is used in mechanical engineering and shipbuilding, oil and gas industry, and production of metal structures.
The bushings 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 bushing affects the service life, cutting quality, and overall performance of the equipment. The worn bushing must be replaced.
The range includes all the necessary plasma tools: electrodes, nozzles, bushings, screens, protective caps, swirlers.
FEATURES
The bushings for plasma cutting equipment are made of standard quality. The use of the components in the correct operating modes extends the tool life and increases the equipment performance.
The insulation bushing prevents burst of the coolant during high-voltage ignition of the plasma arc and the appearance of traces of electrochemical corrosion on the inner surface of the parts.
The bushing is easy to install and requires no maintenance. The consumable tool must be regularly checked and replaced if defects are detected.
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.
