I personally like the beep to tell me when my irons reaches temperature, but I think it’s way to loud. So in this video I show you how to dampen the sound of that Hakko FX-951 beep. I left the paper backing on the opposite side of the tape, and only removed it from the side pressed onto the speaker.
Yes, you can turn if off in the newer firmware with option 5, but I don’t want to turn it off. I just did not want it as loud as it was.
The speaker is 0.45 inches in diameter, so you can used the 1/2 inch tape, or 1 inch and just trim it back. Mine was originally the 1 inch wide tape that I cut back so only the corners of the tape overlapped off the buzzer.
The 3M tape used was:
3M Urethane Foam Tape 4016 - Off-White- 1/16 inch (0.0625 in. (1.6 mm) open-cell, flexible urethane foam carrier that fills gaps,
provides long-term holding at temperatures up to 220°F (104°C). More then enough to stay on from the heat of the transformer.
I think any of the 3M urethane foam tape should work.
Thisntaoe is also sold as the following items you can search for.
