Operator Negligence

This is probably the top cause of damage to high frequency welding machines and seemingly gets the least attention.

While the various issues are to numerous to document here are a few categories of how operators can damage the machines.

    Ignoring minor faults till they become major faults – like flashing (see here),  or mechanical wear and tear
    Being rough with the machine
    Not understanding the basics of how the machine works

When a high frequency plastic welding machine first starts giving trouble you will find certain things occur. Usually the following

    Arcing/Sparking/Flashing at various points on the machine
    A need for more time/power than usual
    An increase in interruptions due to overloads/antiflash events

If you have good operators they should report this to their supervisor who in turn should contact people like us (hey guess what, we repair these things!) or your maintenance staff.

Unfortunately for whatever reason the staff do not report these minor events and may even report them to late. By that time the damage may already be done. What may have cost just a small call out fee now becomes an entire valve/tube replacement (we do those too!).

As valve/tubes are the most expensive item on a high frequency plastic welding machine, and you don’t want to be replacing them often.

Unfortunately it may not just be the tube that is damaged but it could be any other of High Frequency PVC Welding Machine the components in the machine, such as the Rectifiers, transformer, anti flash etc.
