1-5 grade power wind is 800w, 900w, 1000w, 1100, 1200w. When the sealing diameter is less than 30mm, the power should be set to high grade. The sealing speed can be increased when the sealing diameter is greater than 60m, and the power should be set to low grade. Better sealing quality can be obtained. Simple operation panel: simple interface, simple operation, intuitive and clear power, time and switch, powerful function Function Bottle mouth diameter 20 mm: sealing time about 1.5 seconds Bottle mouth diameter 48mm: sealing time about 1.2 seconds Bottle mouth diameter 69mm: sealing time about 0.6 seconds Sealing diameter 80 mm: Sealing time about 0.4 seconds The larger the diameter of the bottle mouth, the less sealing time is needed. Specification Power supply: AC150 270 Power: 0.8-1.2kW Working frequency: 30 5 Sealing diameter: 20-100mm Whole machine weight: 0.8kg Breakpoint memory function: Yes Notes: 1. Only the above list is included. The other products in the picture only show how they are used. 2. Due to manual measurement, please allow 1 3cm error and make sure you don't mind before ordering.Compact and lightweight, simple operation, bonding time is short,fast, fastness strong, stable performance, for small batch production and laboratory operations. Light and easy to carry. Heat sink omni directional heat sink, ventilation and heat dissipation faster to avoid equipment overheating to multiple protection of machine circuit. Rugged and durable with overheating for longer life. The induction disc made of pure copper coil makes the equipment run more efficiently and consume less energy.Pure copper coils are used to make the induction disk, which is more efficient and consumes less energy. Automatic sleep when not working, protect the machine and save more electricity. Safe, the frequency range 25-100KHz, the human body without injury, equipment with overcurrent, overheating and overload protection device. It is safer to use the equipment by thicker and thicker high temperature resistant power cord. Imported modular power supply components, high efficiency low consumption, good performance not only for the sealing of polyethylene, polypropylene containers, Sealing. performance and less on the PET bottles, glass bottles are also good sealing effect.
