Kjellberg SmartFocus 100

The Kjellberg SmartFocus 100 is a precision plasma cutting system engineered for high-definition cutting at the 100-ampere class. Developed by Kjellberg Finsterwalde — the originator of plasma cutting technology — the SmartFocus 100 represents Kjellberg's answer to the demand for laser-like plasma cutting quality on thin to medium plate without laser capital investment. The system is aimed at job shops, precision parts fabricators, and HVAC/ductwork manufacturers who need tight dimensional tolerances and clean dross-free edges on carbon steel, stainless, and aluminum up to roughly 25 mm.

The SmartFocus name reflects the machine's core differentiator: a plasma torch design that uses optimized gas dynamics and precision-bored nozzle geometry to produce an exceptionally focused plasma arc column. This narrow, stable arc minimizes kerf width and heat-affected zone compared to conventional plasma at the same current level. On 6 mm mild steel, the SmartFocus 100 is capable of cut quality approaching laser in terms of edge angularity (ISO 9013 range 3 or better) and surface roughness, making it practical for parts that would otherwise require laser or waterjet. At lower thicknesses (3–8 mm), the system produces near-bevel-free cuts that require no post-processing for weld prep.

Kjellberg has engineered the SmartFocus 100 with operator simplicity in mind. The system features a guided setup interface that presents pre-programmed cut charts organized by material type and thickness, eliminating the need for operators to manually calculate gas pressures, flow rates, or arc voltages. This job-shop-friendly approach reduces consumable waste and setup time significantly, especially when production involves frequent material changes. The SmartFocus integrates with standard CNC table THC systems via analog and digital I/O and is compatible with most major table manufacturers.

Consumable life in the SmartFocus 100 reflects Kjellberg's German manufacturing precision. Electrodes and nozzles are built to tight tolerances that minimize run-out and erosion variability, resulting in consistent cut quality from the first arc start to the last on a given consumable set. The torch design also incorporates anti-splash features that protect nozzle orifice geometry during piercing, which is a common source of premature consumable wear in production environments involving frequent pierce cycles.

The SmartFocus 100 is competitively positioned against ESAB and Hypertherm precision plasma systems in the 80–100 A class. Its German engineering lineage, combined with Kjellberg's deep process knowledge accumulated over decades of plasma development, gives it credibility in European and export markets where quality certification and provenance matter. For fabricators who run stainless steel or aluminum alongside mild steel and need a single plasma system that handles all three with high quality, the SmartFocus 100 is a strong candidate in this power class.
