7. Our advice

To test a new assembly on your machine:

• use the "energy" mode;

• Start with a low energy level, for example 1 J (Joule) on a 20 kHz, 1,500 W machine;

• observe the weld and all the other parameters indicated by the machine at the end of the weld and test the quality of the weld;

• Analyze the figures based on your specifications and experience;

• depending on the results, refine to around 1 J, or increase the energy considerably to 50 J, for example;

• repeat until your weld is in order.
