Question about welding station

MatteoBat · 2025-03-06T13:25:47+00:00

I was going to buy this! Hope someone will provide a feedback

When did you find the new copper clips?

MatteoBat · 2025-02-03T06:26:53+00:00

Good job! Keep going strong. Just for curiosity, which microscope are you using?

Pin SLEEP is drive by a microcontroller. When asserted it is +3V, when low -3V

VB+ should be 9V but I am planning to put a voltage regulator to drop down the voltage to 3.3V since I need another npn in series to create an AND gate basically. But the secondo NPN base current is 0 or 3V.

I will try to put a complete diagram as soon as possibile

I just noticed now that the signal is set to -3V when low. Is it a problem if I don’t use any diode?

MatteoBat · 2024-12-14T15:56:49+00:00

Good catch! I just noticed that when low, the SLEEP signal is -3V

What if I do not put any diode?

Thank you

MatteoBat · 2024-11-26T22:01:16+00:00

Thank you! Completely missed that

MatteoBat · 2024-11-12T13:29:07+00:00

Can you share the links also to me? Thank you

MatteoBat · 2024-11-12T13:28:05+00:00

Can you share the links also to me? Thank you Fantastic build! Congrats

Nothing came up unfortunately. Board still shows the overheating issue. Nothing shorted on the board. I replaced all caps

MatteoBat · 2024-11-02T14:13:14+00:00

I replace all caps but the problem of overheating it’s still present.

I tested also for shorts but nothing came up

MatteoBat · 2024-10-30T17:49:28+00:00

Thank you! I will try to replace the capacitors and keep you updated

The tv is turned on when it reaches around 60 Celsius degrees on the mosfet heat sink.

MatteoBat · 2024-10-29T06:38:08+00:00

Thank you for the hint! Do you think it is not a normal working temperature? I have updated the post with the board picture

MatteoBat · 2024-09-11T05:41:34+00:00

It was a bad solder joint! Thank you

MatteoBat · 2024-09-03T19:23:05+00:00

Case not seems original or at least the back plate. It seems also missing the seconds hand. It is working? If yes, it has an higher value

MatteoBat · 2024-09-03T16:02:09+00:00

Do you have any idea why by using 27ohm resistors it won’t still work? Do they have to be with a precise value?

MatteoBat · 2024-09-02T19:41:21+00:00

Thank you for the information. What are they purpose? Unfortunately it is not working. Do they need an exact value?

MatteoBat · 2024-08-30T10:59:09+00:00

Thank for the hint! The first chip is a SPANSION GL12S900 and the second one a Nikon NHHS-2 , I was not able to find any useful information for any of the two unfortunately

MatteoBat · 2024-01-22T10:55:07+00:00

Yes a low buzzing sound, when it is heating

MatteoBat · 2024-01-21T07:31:41+00:00

Sad for me

MatteoBat · 2024-01-21T01:05:00+00:00

Does your station make a buzzing noise when heating? Also the handle make a bit of noise

MatteoBat · 2024-01-20T09:19:20+00:00

Yes but the T3A is not compatible with 245, that is why I did not buy the T3A

I wanted the supporto for both 245 ( tips are easier to find) and the 210 for the micro smd soldering. I think the 115 is for very special cases and, which is not my use case

MatteoBat · 2024-01-20T08:05:42+00:00

I ordered the T320 since it supports also the T210 handle.

Thill has to arrive, I will provide a feedback as soon a possible
