Plasma cutting unit with ^PLUS technology.

Plasma cutting machine FineFocus 800 and FineFocus 800/TWIN now with ^PLUS technology preferred for automated and mechanized cutting of all electrically conductive materials on cutting tables or with robots; with or without swirl-gas; also under water.

• Cutting range up to max. 80 mm thickness (material depending), quality cut up to 60 mm thickness, piercing with arc-voltage controlled height-sensing system up to 40 mm thickness
• Outstanding cutting quality and longevity of nozzles by swirl-gas technology
• Metallically clean cutting edges, dross free resp. nearly no dross
• Multiple-gas regime for plasma gases air, O2, Ar/H2/N2, Ar/H2, ArN2 for cutting results normally free of after treatment and therefore cost saving
• The plasma cutting machine FineFocus 800 is a unit with only one plasma torch connection
• Plasma cutting machine FineFocus 800/TWIN means: Unit with simultaneous connection of two plasma torches and changing use depending on process

Equipment possibilities:

• FineFocus 800 compact = direct plasma torch connection; torch hose parcel max. 15 m length
• FineFocus 800 distance = plasma torch connection via plasma ignition box and hose parcel extension, range of action max. 55 m from power source
• FineFocus 800 Robo = with special plasma torch for robot application

Characteristics of the FineFocus 800:

• FineFocus technique with ^PLUS technology for mild steel with the slightest inclination tolerance and very high cutting speed
• or Double-Straight-Effect for the technological use of both cutting edges, no waste
• Cutting with suction (dry-plasma cutting) or cutting under water (UWP)
• Metallurgicaly perfect cutting edges by XL-Life-Time System for cutting of mild steel with oxygen; no after treatment for the following welding operation necessary
• High reliability of plasma torches through a direct and extremely effective cooling of the beam generation system and the torch head
• Manual plasma cutting with powerful hand torch PB-S75 WH-1 up to max. 80 mm thickness (material depending)
• Step-less adjustable cutting current between 80 A and 300 A at 100 % duty cycle
• Plasma rectifier with 12-pulse circuit for an extremely smooth cutting current; high efficiency and power factor
• Excellent suitable for CNC-controlled application
• Contact-less high-voltage ignition for start of pilot arc
• Direct pre-selection of plasma gases and plasma gas mixtures (O2, air, Ar/H2, Ar/H2/N2)
• Quick adaptation to numerically controlled guiding systems by serial, compatible interface
• Pre-selection of rate of current rise for a nozzle saving process
• Preset control for pre-selection of cutting current and digital display for cutting current and arc voltage
• Select-control for setting of cutting current from potentiometer of power source by remote control or CNC system (cutting table, robot, direct setting)
• Service-friendly diagnosis system for control and monitoring of working conditions: Stand-by, pilot arc, main arc, pilot arc limitation, nozzle protection circuit, control mains connection, coolant flow, coolant temperature, plasma gas, thermal overload, cumulative error
• Correspond to highest safety regulations according to BGV D1
