How much does the Kjellberg HiFocus 440i neo cost?
Price estimate
We do not have a price for the Kjellberg HiFocus 440i neo that we can stand behind, so we show no number. Configuration, options and installation move the final price a long way: a quote is the reliable figure.
Overview
The Kjellberg HiFocus 440i neo is the largest single-cabinet power source of the HiFocus neo range. It delivers 440 A at a 100 % duty cycle and is listed with a cutting range of 0.5 - 120 mm (0.02 - 4.7 in) in mild steel and 1 - 120 mm (0.04 - 4.7 in) in stainless steel.
The distance between maximum and recommended range is wider here than anywhere else in the family, and it differs by material. In stainless steel the recommended range is 0.5 - 80 mm (0.02 - 3.1 in); in mild steel it is 0.5 - 60 mm (0.02 - 2.4 in). Piercing is listed up to 50 mm (2.0 in). So the 120 mm figure describes edge-started cuts in heavy sections, and stainless steel is the material where the extra current pays off most.
A buyer weighing it against the HiFocus 360i neo should look at exactly those rows. Piercing is the same, up to 50 mm on both. The mild steel recommended range matches the 0.5 - 60 mm of the 360i neo. What the 440 A source adds is the stainless band up to 80 mm and the reach to 120 mm.
That reach has a price in infrastructure. The slow fuse is 200 A and the connected load is max. 127 kVA on 3x 400 V, 50 Hz, the heaviest single connection in the range. The cabinet is the shared 1030 x 680 x 1450 mm housing and weighs 589 kg (1,299 lb). The torch is the PerCut 451, one of the two torches the PerfectBevel bevel cutting database is based on, and an underwater cutting version is available.

Strengths & Limitations
Strengths
- 440 A cutting current at a 100 % duty cycle, adjustable across 10 - 440 A
- Cutting range to 120 mm in both mild steel and stainless steel
- Recommended range of 0.5 - 80 mm (0.02 - 3.1 in) in stainless steel
- Piercing up to 50 mm (2.0 in)
- Also available for underwater cutting; HotWire is optional
- PerCut 451 torch, covered by the PerfectBevel bevel cutting database
Limitations
- In mild steel the recommended range ends at 60 mm, half of the 120 mm cutting range
- Piercing stops at 50 mm, so heavy plate is always edge-started
- Requires a 200 A slow fuse and a connected load of max. 127 kVA
- The stainless steel cutting range is listed from 1 mm, not from 0.5 mm as for mild steel
- Weighs 589 kg in a single cabinet

Frequently Asked Questions
01
The cutting range row lists 0.5 - 120 mm (0.02 - 4.7 in) for mild steel and 1 - 120 mm for stainless steel. The series brochure gives recommended ranges of 0.5 - 80 mm in stainless steel and 0.5 - 60 mm in mild steel, with piercing up to 50 mm.
02
On the listed figures the two are close in mild steel: the recommended range of the HiFocus 360i neo is 0.5 - 60 mm and its piercing figure is up to 50 mm, the same as here. The 440i neo extends the cutting range to 120 mm and adds a stainless steel recommended range up to 80 mm.
03
It connects to 3x 400 V, 50 Hz. The series brochure lists a 200 A slow fuse and a connected load of max. 127 kVA. Other voltages and frequencies are available upon request, according to the maker.
04
Yes. The series brochure lists bevel cutting from the HiFocus 280i neo upward, and Kjellberg's PerfectBevel database of bevel cutting values is currently based on the PerCut 451 and PerCut 4000 torches. The PerCut 451 is the torch listed for this power source.
