The best high frequency welding machine suppliers is davison-machinery's High Frequency Welding Machine >>>> Hot air welding of PVC is an alternative to high frequency welding of PVC. In high frequency welding we use radio waves to heat the two materials directly at the point of contact. Whereas in hot air welding, it usually involves a heatgun to melt the PVC. This is followed up by a roller to press the PVC together resulting in a welded joint.
Pros of Hot Air Welding
There are some great pros to using hot air welding, for example,
It is portable
Great for repair work. Especially where only a little bit of welding is needed.
Relatively fast
No need for 3 phase power or compressed air
Cons of Hot Air Welding
However there are also some large cons, such as,
Far weaker weld than that of a high frequency welding machine
Not suitable for large repair work
May rip or fail if there is moderate tension applied to the pvc canvas
Will perform terribly in unskilled hands – spotty welding, burnt patches and other problems.Top Quality High Frequency Welding Machine By Davison-machinery !
