The Kjellberg HiFocus 360 is a plasma cutting system in the transformer version. The machine holds 360 A at a 100% duty cycle, it cuts steel up to 80 mm and pierces up to 50 mm. The weight of the unit is 517 kg.
What this machine is for
This is a power source for steel service centres, shipyards and plants cutting thick plate on numerically controlled tables. A 100% duty cycle at 360 A means cutting without breaks for cooling, through a whole shift and longer. The maximum cutting thickness in structural steel reaches 80 mm and the piercing capacity 50 mm, which draws the line between cutting from the edge and piercing in the material.
The transformer version weighs over 500 kg, because it has heavy output chokes and large magnetic parts. That weight turns into a stiff characteristic and a steady arc, and into resistance to dust, swarf and voltage swings in the plant mains. This is a system for continuous work, not for moving between stations.
The High Precision technology limits the bevel on the edge. The description puts the edge quality in class 2 to 3 to ISO 9013, that is in the band usually tied to laser cutting. Contour Cut lets you cut holes with a diameter to thickness ratio of 1 to 1, so the part comes off the table without reaming. The cutting speed in steel of 20 mm thickness the description gives as 1700 mm/min, and you mark and centre punch with a current from 5 to 50 A.
Features and equipment
- Transformer power source in the heavy duty version, 100% duty cycle at 360 A.
- High Precision and Contour Cut technology, holes with a diameter to thickness ratio of 1 to 1 without reaming.
- FlowControl gas control and work with torches of the PerCut line.
- Closed Kjellfrost coolant circuit, the liquid reaches the cathode and the nozzle directly.
- Wear parts in the YellowXLife line, the description gives up to 3.5 times longer electrode life than with standard solutions.
- Marking and centre punching of parts with a current from 5 to 50 A.

What to watch out for
The weight of 517 kg calls for a fork lift, a prepared place and a strong floor, and you plan the unloading and the setting up ahead. The description gives no supply voltage and no gas requirements, so confirm the setup before you buy, and the same for the needs of the compressed air or industrial gas line.
The item name gives the marking HiFocus 360A and the description the 360i version, so settle the exact marking of this unit before you buy as well. Torches of the PerCut line and YellowXLife wear parts you buy separately, the description does not list them in the set. Liquid cooling means you check the coolant level, the flow and the tightness of the circuit before every start.
How we sell used machines
This unit was checked in our service workshop in Krotoszyn with measurements to PN-EN 60974-4 and a load test. The price includes the first year of the basic service package: an inspection with cleaning of the machine and a validation measurement. Further years can be added. We ship across the European Union, collection in person by appointment.
