Hi. After a long time of buying a soldering iron from Aliexpress, I unpacked it and when I tried to turn it on, the display didn't show anything. Then I realized that it turns on by pressing one of the buttons for 2 seconds. My soldering iron has 3 buttons, + - and on. That first time, when I saw that it didn't turn on, I opened it and the display came off, it wasn't firmly attached. When I put it back on, the degree numbers on the display are barely visible. I don't know how to fix it.
Plz help me, i need your help, i used this soldering iron, but unfortunately today open soldering iron and my heating element broken, so I need your help, please say me which model this heating element was, and give me the buying link
I want to know the value of resistance cylinder shape with colour coding placed just above the 0.1mf SMD Capacitor. My soldering iron resistance is burnt and colour coding is not visible. Please help.
Yes, as the circuit only regulates the power by chopping off parts of the mains voltage for example 50% results in the triac activating 10 milliseconds later (50 Hz, period - 20 ms). But if your tip is glowing.. add a diode, the 1N4007 will be enough.
Bro, do you know if the 110V and 220V versions have the same pcb components? I wonder if the label 110/200V are only on the ceramic heating element? I am asking this because I wonder if it's possible to change a 110V rated ceramic element with 220V.
Thank you very much bro it helps me lot

So clear
Start here => 06:54
Thank you.
Gracias por el dato.👍👍👍👍👍🙂🙂🙂🙂🙂🙂🙂
Bang...tegangan 80vac nak turun ke 70vac mcm mana ye...Solder adjustable selalu rosak mata tip sebab volt tinggi

150Ω, size 6038,
I got one already dead from aliexpress, if anyone can help me fix it i would appreciate

100 Ω
Can I connect heating element directly to 220v because circuit is broken?
you should disconnect the power before the soldering tip goes to hot to red~
Yes, as the circuit only regulates the power by chopping off parts of the mains voltage for example 50% results in the triac activating 10 milliseconds later (50 Hz, period - 20 ms).

no not the same, the 0.1uF
cap next to the bt136, is different from 220 and 110V version, and the program inside mcu, they are not the same one
Slight differences, because the TRIAC (BT136) circuit inside can run on mains voltage. What really needs to be different is the heating element.
They have different heating element. The one for 120V has 64 ohms while 220V has 146. I changed mine with 146 ohms 80watts.@@imnotbeluga007
So to confirm, the spring here is the temperature gauge of the iron, right?
Obviously not, it's supposed to be ground.
Indeed. Is there anything.
soldering iron ar name ki vai plz sms a bolban ar praise koto market a plz
You pud wa a rai na?
Please see in Description
You call that tiny work lol try soldering a 0402 cap
I can hand solder them perfectly only problem I have is them sticking to the tweezers lol
