I bought budget soldering pen called Zhaoxin X4. We know it burn

OP here.
It should be more like 120V cause getting source of 20V by 2AMPs is not easy.
But maybe laptop adapter could be used. Almost all of them provide like 20V / 2Amps.

Why did you buy a soldering pen if you wanted a heater?

I didn't wanted just a heater. im thinking about future heater when this one burnout.
But i can see there is nowhere to buj this kind of wire, like 1k and 1 meter long and about 0,1mm diameter. I am condemned. Or to use 24V heaters and try to use some adapters...

These irons are 100% garbage, don't buy soldering irons that plug in directly to mains. They have no temperature regulation and work like a runaway train, thermally speaking. You're better off getting a real soldering station once this iron burns out. There are some cheap chinese Hakko clones that aren't good, but at least have temperature regulation. They go by "Yihua 936" and thousands of other names, usualy with "936" next to it. AFAIK you can use genuine Hakko tips with them.

nichrome or kanthal wire

there are numerous calculators that you can use for length/temperature/resistance

Yea I will buy that one, 936 or so. Im tired of buying some irons every half year (i work with electronic rarely anyway)

Im thinking now about to find 20-24 transformer or adapter with 2Amps, and just change heater when this one go fucked.

Hi guys, can I use a light switch dimmer to control the temperature?

I did. But it would be good to see that temperature.
i made some simple AC triak bt136 regulator.
