Frequently Asked Questions (FAQ):

1. Which materials can the VS-340M clean?

Metals: stainless steel, copper, aluminum

Plastics, ceramics, glass, rubber

Intricate parts: electronic boards, connectors, jewelry

2. How do I select the right ultrasonic frequency?

Low frequencies (20 - 40 kHz) generate larger cavitation bubbles for heavy deposits.

High frequencies (40 - 200 kHz) produce finer bubbles for delicate surfaces and small crevices.

VS-340M offers five preset frequencies - test each to find the optimal setting for your parts and contamination.

3. What cleaning solution should I use?

Use a neutral or mildly alkaline ultrasonic detergent.

Avoid flammable solvents, strong acids, or concentrated alkalis.

Proper detergent lowers surface tension, boosts cavitation, and improves overall cleaning.

4. What is “degas” and when should I use it?

Degas removes dissolved gases from the liquid before the main cleaning cycle.

Run a 3 - 5 minute degas whenever you fill with fresh solution to maximize cavitation power.

5. How long should each cleaning cycle be?

Light contamination: 3 - 5 minutes

Moderate deposits: 10 - 15 minutes

Heavy soils: 20 - 30 minutes (repeat cycle if needed)

Always inspect parts between runs to prevent over-processing.

6. How do I maintain and clean the machine?

Drain and rinse the tank every 50 - 100 hours of operation.

Inspect O-rings, drain valve, and transducers for wear or leaks.

Wipe down the exterior with a damp cloth; never use corrosive cleaners on the steel housing.

7. What safety precautions should I follow?

Never put hands in the tank while it’s running.

Ensure the unit is properly grounded; keep water away from the control panel.

Do not use flammable or highly corrosive liquids.

Rinse parts and tank thoroughly with clean water after each cycle.
