    Rewiring a soldering iron, that only has 2 wires

    Bought an soldering iron online and didnt notice it was a lighter socket on other end instead of plug so cut off end intending to wire it into a plug.

    What is worrying me is since it has 2 wires will it be safe? I guess a 3A fuse is best as my other soldering iron has one of them.

    I would take a guess with it having a lighter socket your device is 12v not 240v as per what your plug will supply

    Sounds like live and neutral with no earth, do you mean an actual socket for use in cars?

    As above it will likely be 12v, you can wire a plug to it but you will need an inverter or 12v battery to run it.

    Yep, looked at packet and it says 12v 40watt

    There you no can do with putting a plug on it

    Ah well, what a waste then.

    have you got another soldering iron to join the lighter plug back to it?



    I have one but it is a awful one which is why I bought this one in first place as it used to liquify solder before you had a chance to use it and 3 people couldnt get it to work!

    Unless you have a 12v transformer somewhere. But tbh, I don't think it will chuck out the wattage, cheap enough though to get a new'un.

    get a gas one, then theres a good chance you be able to start a thread … get a gas one, then theres a good chance you be able to start a thread about how a simple soldering job turned into a major rescue for the fire brigade



    Ooh no Im reasonably good at repairing things and tried a good soldering iron before.

    WTF? Sounds like none of them (including yourself) had a clue what you were doing then. How can it 'liquify solder' before you have chance to use it?

    Rather than wasting more money, look at some tutorials and videos and learn how to solder.

    How else do you think a soldering iron works>?

    It melts Solder - ie liquifies it

    Was expecting someone to mention this, considering my friend is finishing his 3rd year in engineering where he solders regularly and my other did a HNC in electronics and neither could get it working means it was just a bad soldering iron!


    What I meant by it liquifying before you had a chance to use was that even trying to tin it, it wouldnt do it as the solder would just melt rather than go on the tip but I assume it was because the soldering iron was far too hot.

    The solder isn't meant to go on the tip - save a tiny coating to aid conductivity of heat. Its meant to go on the thing you are soldering. The soldering iron heats that up to the point where the solder will flow. It might have been a crap iron, yes, but not as crap as your (and your 'friends') technique.

    Yes I know all of this, and what are you implying by writing "friends"

    If you 'know' this then comment '#8' makes 'no sense' whatsoever, but then given the 'original post' and comment #4 i've 'serious doubts' you have 'a clue' what you are doing at all, if anything you are a risk and a liability to yourself and your 'friends' [which means whatever "you want" it to mean, by the way].

    Well like you say then I guess my comments mean to you whatever you want them to think too.

    And for the record I have rewired plugs many a time before, I have ven done things like rewire a broken plug socket safely, I am quite a bright person but when I have little experience with something I like to confirm that I am doing the right thing.

    How do you know you have rewired something 'safely', especially if you don't know the difference between 12V DC and mains electrics?

    Its quite a bold, or perhaps misguided statement to make. Would it pass BS7671?

    its quite worrying that someone who obv hasnt a clue tries messing with things like this-an accident waiting to happen imo

    Don't do it if its got a lighter socket it's going to be 12v, just go buy another soldering iron before you trip the house out or worse blow yourself up

    I have a chainsaw that is playing up. Would you be so good as to have a look at it for me?
