Smart Focus 130 / 200 / 300 / 400 plasma systems 35–400 A for machine cutting

Country: Germany · Model: Smart Focus 130 / 200 / 300 / 400

The four Smart Focus 130, 200, 300 and 400 plasma power sources deliver a cutting current of 35–130, 35–200, 35–300 and 35–400 A at 100 % duty cycle and work on CNC coordinate machines. The top model cuts metal up to 100 mm and pierces up to 50 mm. The series is used for cutting structural and stainless steel and aluminium where repeatable quality is needed in heavy-duty conditions.

Description

The Smart Focus 130 holds steady cut quality, the Smart Focus 200 cuts and marks flexibly in demanding conditions, the Smart Focus 300 is made for serial production, and the Smart Focus 400 for critical cuts of large thicknesses. A marking current of 10–50 A is enough for individual marks on parts. Plasma is formed by O2, Ar/H2, N2 or air, and piercing is done in argon or nitrogen. Accurate holes with a diameter to thickness ratio of 1:1 are cut with Contour Cut, with Contour Cut Speed the same quality comes up to 50 % faster, stainless steel and aluminium of 1–6 mm are cut with HiFinox, and from 6 mm with an Ar/H2 mixture. The Smart Focus 400 is supplied with the PerCut 4000 torch, including a quick-change head version, and the cabinet measures 1030×680×1450 mm and weighs 563 kg.

How to choose

The model is chosen by the thickness the shop cuts every day, not by the limit. From SF 130 to SF 400 the recommended ranges are 1–32, 1–40, 1–60 and 1–70 mm, the maximum thicknesses are 40, 60, 80 and 100 mm, and piercing is 25, 30, 40 and 50 mm. For precision cutting of thicknesses up to 160 mm look at the HiFocus neo, and for manual cutting and robots at 60–200 A the K 200 source.

FAQ

What thickness does Smart Focus 400 cut?

Up to 100 mm with a recommended range of 1–70 mm and piercing up to 50 mm. The current is adjustable within 35–400 A at 100 % duty cycle.

Which gases does Smart Focus need?

The plasma gases are O2, Ar/H2, N2 and air, and argon or nitrogen is supplied for piercing. Several gas lines are connected to the machine, and a compressor alone is not enough.

How much quieter does Smart Focus cut with Silent Cut?

At currents of 60–160 A Silent Cut reduces the sound pressure level by up to 15 dB(A), which is noticeable for operators near the machine.

What is the supply voltage of Smart Focus?

The standard version is connected to a 3×400 V, 50 Hz mains supply, and other voltages and frequencies are supplied on request.
