CUTFIRE 70 / 90 / 105 / 125 air plasma cutting machines 20–125 A
Country: Germany · Model: CUTFIRE 70 / 90 / 105 / 125
The CUTFIRE 70, 90, 105 and 125 air plasma cutters cut structural steel at currents from 20 A up to 70, 90, 105 and 125 A, with a maximum thickness in the series of 60 mm. Plasma is formed by compressed air, so a three-phase supply and a compressor are enough to work. They are used for repair and installation work, in workshops, in blank preparation areas and on simple cutting machines.

Description
The series is mobile, and the machines cut manually and in mechanised mode. The CUTFIRE 70 is made for workshops and field work, the CUTFIRE 90 for varied metalworking tasks, the CUTFIRE 105 with a 100 % duty cycle for workshop and production use, and the CUTFIRE 125 for large thicknesses, and besides steel all of them cut other metals. The KjellCut 125 (manual) and KjellCut 125M (machine) torches are air cooled, so there is no liquid cooling unit. Power is three-phase 380/400/415/440 V ±10 %, 50/60 Hz, the IP 23 housing is protected against splashes, and the machine can be taken out to an installation site. Weights are 28, 30, 45 and 49 kg, and dimensions are 585×303×505 mm for the CUTFIRE 90 and 678×390×610 mm for the CUTFIRE 125.
How to choose
The machine is chosen by the everyday thickness and by the length of continuous work. Recommended steel thicknesses are 20, 25, 30 and 40 mm, limit thicknesses 35, 40, 50 and 60 mm, and piercing 15, 20, 20 and 25 mm. The duty cycle at 40 °C and a 10 min cycle is 60 % for the CUTFIRE 70, 80 % for the CUTFIRE 90 and 100 % for the two higher models, so the 105 or 125 is taken for a cutting machine. For the CUTFIRE 90 the description gives a current of 20–90 A and the table 20–70 A, so confirm the upper limit when ordering. For CNC cutting of large thicknesses there are the iQ and Smart Focus systems.

FAQ
What steel thickness does CUTFIRE 125 cut?
Recommended is 40 mm, maximum 60 mm, with piercing up to 25 mm at a current of 20–125 A and a 100 % duty cycle.
Is a separate gas needed for CUTFIRE?
No, plasma is formed by compressed air from a compressor, and cylinders with industrial gases are not needed.
What power and fuse should be allowed for CUTFIRE?
Consumption is 16.1 kVA for the CUTFIRE 90, 18.9 kVA for the CUTFIRE 105 and 21.6 kVA for the CUTFIRE 125. A 32 A fuse is used for the CUTFIRE 90 and 63 A for the CUTFIRE 125.
Can CUTFIRE be installed on a cutting machine?
Yes, for mechanised cutting there is the KjellCut 125M machine torch with air cooling, and the 100 % duty cycle of the CUTFIRE 105 and 125 means cutting can go on without pauses.
