ELNA HFG 3-5 V 1011 High Frequency Generator

High Frequency Generators - Series HFG 3-5 and the equipment for them, are used for body and shoulder welding in tube producing machines as well as for sealing of already filled tubes. The generators include inductors and modules for different type of welding and controlling the processes of packing machines.
The HF generators are designed on the basis of power MOSFET transistors and they work in the frequency range 250 – 370 kHz and output power 5kW. HFG 3-5 is designed for welding of laminate tubes, made of ABL (aluminium barrier layer) and PBL (plastic barrier layer) foil. The tubes welding is performed under direct induction heating, when using ABL and indirect, when using PBL.
The generators have an option to control the welding time from 0,01s to 1s by steps 0,01s as well as to control output power from 50 to 100%. There are modifications of generators adjusted to work in continuous mode, too (HFG 3-5C) - for special purposes.
