Arc cutting machine

A packaged arc cutting machine KEDU-04 is developed by the «Composite Materials» Ltd. and is fabricated since 1989. The equipment allows cutting steel and cast-iron scrap, bimetals, titanium, aluminium and bronzes scrap. The machine forms the electric arc between the cut metal and the graphite electrode, due to the high temperature of the arc the metal melts in the cutting area.


Arc cutting machine KEDU-04 advantages:

- Abound cutting possibilities (nearly any metals and alloys).

- High efficiency.

- Capacity of one set is up to 6 cutting sections.

- Various thickness of cutting metal.

- Convenient consumable material – graphite electrodes.

- Operation temperatures -40 to +40ºC.

- Operation and servicing reliability and simplicity.

- No surface cleanliness and cut metal configuration requirements.


The arc cutting machine KEDU-04 was designed especially for metals scrap processing enterprises. The key peculiarities are simplicity, operation reliability and generality. The machine can cut almost any metals and alloys. The operational requirements are current source for 380 V and . Dirt, rust or protective coatings on the metal do not influence the cutting rate. The multisection division wall is possible in one trail.


Technical- economical characteristics:

Capacity at thin-walled metal cutting (for a single manual cutter):

- ferrous metals – up to 1000 t/month.

The consumptions for steel scrap cutting of 3A size:

- power: 50 -100 kW*hour;

- graphite electrodes: 1.5 – 2 kg.
