This machine is a high frequency device, whose self-exited oscillator of the electron tube can produce high frequency electromagnetic field. And the plastic to be processed is in the high frequency electromagnetic field between the upper and low electrode. When its interior molecules are polarized and produce heat automatically by mutual movement and friction, it will be welded with the pressure of the die.
1. Anti-spark electric system
When the spark occurring, the high sensitiveness spark electric system will cut the high frequency power immediately to protect the mould and material.
2. Jamming Prevention Device
Equipped with high frequency stabilizer and magnetic leakage suppressor, this device can prevent the leakage of electromagnetic radiation to avoid other electrical instruments jamming such as televisions and radios, etc.
3. Safety Device
When the current over its limit, the overload relay works automatically to protect the oscillation tubes and rectifier. The frequency deviation caused by mistake is avoided.
4.The Special Mechanical Structure
With a excellent design and structure, the machine can works precisely and intensively.
5.Easy Tuning And Special Protection Circuit
The selectable output power can ensure the stable quality of the product. While the welding process, it could largely reduce the heating time.
6.Pneumatic Pressure Device
It is provided pneumatic pressurizing device, which can adjust the pressure in the practical situation, greatly decrease the operation difficulty and impaction equipments, changing the controlling method may modify the high-frequency process technology.

a. Add oil lubricant in each function parts every several days, and often wipe cleanly.
b. To cleanout and lubricate each parts of the machine every half year, clear away the dust in the parts of transformer, high voltage capacitor, blower fan and Resonant Cavity.
c. f the aluminium pan of the output adjusting capacitor and the capacitor in the side of resonant cavity, was ablated by caustic caused by dust or eyewinker, the caustic surface should be repair flatly and smoothly in time.
