Question: Why uv liquid not dry on the mini UV coater ?

Answer :

There are 3 possible reasons for the UV varnish not dry.

1. The UV tube's life time is 800hours. If you use up to 800 hours, you need to change the UV tube.

2. The UV varnish maybe too thin, it has been added too much alcohol.

3. Watch if the UV tube moves smoothly when the machine works, if the UV tube does not move smoothly, you need to add some grease oil to the metal bar of the UV tube. If the UV tube does not move smoothly, the metal bar may need some grease.
