1. Safety device
When the current exceeds its limit, the overload relay functions automatically to protect oscillation tubes and rectifier. Frequency deviation caused by misoperation is also prevented.
2. Strong Foot Pedal Machine using a special designed mechanism, the maximum pressure of foot pedal can reach up to 400KGS so as to meet most operating conditions. The high quality components make these machines work very smoothly and precisely.
3. Easily Adjustable Tuner Machine output power can be adjusted at the tuner according to electrode size and material thickness. In addition, other control devices and special electrical circuits have cut down required welding time considerably to raise the machine productivity.
4. Jamming Prevention Device High frequency welding machine equipped with frequency stabilizer and high frequency magnetic leakage suppressor, this device provide leakage of electron magnetic radiation to avoid jamming other electrical instruments such as television and radios etc.
Machine Working Principle
HF Welding relies on certain properties of the material being welded to cause the generation of heat in a rapidly alternating electric field, so called dielectric heating of the material to be welded.
This means that only certain materials can be welded using this technique. The dynamic electric field causes the molecules in polar thermoplastics to oscillate.
Depending on their geometry and dipole moment, these molecules may translate some of this oscillatory motion into thermal energy and cause heating of the material. A measure of this interaction is the loss factor, which is temperature and frequency dependent.

Final products done with HF welding Common products manufactured with HF welding method are Binders, folders, rings, files, tarpaulins, tents, ceilings, advertising outdoor banners, waterbeds, inflatable boats, drip and blood bags, tensile structures, conveyor belts, rain clothing, etc.
What material can be HF welded The material most common in high frequency welding in PVC (something called simply vinyl) and PU (polyurethane). The material can be thick or thin, reinforced or coated. It cab also be plain, coloured or structure/patterned.
Polyvinylchlorde (PVC) and polyurethanes (PU) are the most common thermoplastics that are weldabele by HF also it is possbile to perform HF welding on other types of materia inculding naylon, PA, ABS, modified TOP, PETG, but particular attention should be pay on working parameters. HF welding is not suitable for PTFE, polycarbonte, polystyrne, polyethylene or polypropylene. Howeve, a special type of mixed fabrics have been produced recently, which have the capability to be HF welded.
