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. Turn Table Working Station
This machine have two working station in trun-table, that mean machine can be alternately working by one worker control, more suitable for simple work-piece welding.
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 Parameters 
Application
Final products done with HF welding
Common products manufactured with HF welding method are tarpaulins, tents, ceilings, advertising outdoor banners, waterbeds, inflatable boats, drip and blood bags, tensile structures, conveyor belts, rain clothing, etc.
What materials 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.
