Outstanding Features: Auto-tension control. Continuous fixed-length cutting mode Minor adjustment at the cutting edge for the continuous cutting Automatic tab welding and taping function is integrated with electrode cutting PLC Touch screen control panel MTI has granted the patent 201821974061.8 for the Automatic Slitting Machine MSK-520/MSK-521 series since September 2019.SPECIFICATIONS: Working Voltage Single-phase 208~240VAC, 50/60Hz, 4 kW Feeding Material Requirements Electrode Roll: 6-80 mm (W), 50-800 mm (L), O.D. ≤ 400 mm, I.D. is 3" for loading on roller. Tab Roll: 1.5 - 4 mm (W), 20-70 mm (L), O.D. ≤ 400 mm, I.D. is 80mm for loading on roller. Protection Tape: 6- 20 mm (W), 6-80 mm (L), O.D. ≤ 200 mm, I.D. is 3" for loading on roller. Winding Alignment ±0.5 mm Cutting Position Accuracy ± 0.3mm Tab Welding Tensile Force >8 N Tab length outside of trail 6-30 mm Part Lifetime Lifetime for electrode blade: 500K times Lifetime for tab blade: 500K times Lifetime for welding head: 500K times Compress Air Requirement 0.5~0.8MPa (Please note that an air compressor is a need for the operation of this machine. Air Compressor is not included. please click here to order or order from your local hardware store) Attention: If a gas cylinder is used instead of an air compressor(pic2), a two-stage pressure regulator(pic1) must be installed on the gas cylinder to limit the pressure within the required working range for safe operation.
