  1. I'm sorry for chris he does great videos and explain a lot in a great way… But the union of the two wires he made is very poor mechanically. If you do it right you don't need to solder, and it will never come off. I would explain but it is easier to watch a video on YouTube.
    In highschool our teacher tested the unions we made (without soldering) by force, separating it with his hands. If it came apart you had to do it again. So I do great unions.
    A good union prevents oxidation. And if you want to solder the union, it will be easier and cleaner. And a lot more resistant to mechanical forces. That's very useful if you do a job for a wire that will have some traction, like a lawnmower. There are various kinds of unions. There is one very easy that works grear most of the time. Oh, and if you do a good union and you solder it, you dont need helping hands. The wires hang on by themselves. They won't come apart. You don't have to rely on the force produced by the soldering itself.

    Also, you can use perfectly a simple and cheap soldering iron, like the one that had shown Chrisfix first. It will be slower but totally possible. He is right that if you have a thick wire will be almost impossible. You need more power, 30 w are enough for 2.5 maybe 4 mm2 of section.

    At last, you don't need silicone as insulation. It's overkill. Maybe if you need it waterproof… But the important thing is that you do it tight so air doesn't come and oxidizes Cooper. With tin, you don't have problems with oxidation. With Cooper, that is no solder, maybe in a few years you have some resistance and the copper becomes brittle.

    You can also use electrical tape. It's easier. Maybe worse but it's very ok. I don't mind. You don't need to have all sizes, just one, and cut the amount you need. Just do it tight and it's alright.

  2. This is beautifully explained. Subscribed!

  3. Not everything os correct but for soleone who knows nothing about solderikg its usefull

  4. hey Chris, do you use a copper sponge to clean as well?

    This tutorial was fantastic because there wasn't an agenda for brand specific equipment. Just a good dude doing good stuff and showing how he did it. 10/10 will watch and share.

  5. Thanks man. I learned a lot. Really good video.

  6. a falling soldering iron has no handle. dont try to catch it if you drop it.

  7. The legend that keep giving

  8. Dude I got a BB 8 and it had a yellow sensor wire I cant solder. Suck dude just ain't fair. I like this hero droid spin master

  9. ok good till you said acid would eat the plastic… acid will eat the copper over time!!
    geezz!!

  10. Haha I have the same soldering gun so maybe I should have watched this video before soldering my cars fusible link wire

  11. Will two pairs of heatsinks (eg pliers) not be needed to protect the insulation, especially if a Heatgun is used rather than a Soldering Iron?

  12. This an excellent video, so well made.

  13. Why did I watch this video? I honestly don't know, possibly to laugh at some newbie telling me how to sodder, woops, Solder. I started soldering 62 years ago and have been in many professions requiring the art. From building home made electronic gadgets to working on the F15 missile control black boxes or repairing VCRs.

    I found this video to be the best I've had the pleasure of watching. I'm still not convinced on that Weller soldering gun, I prefer the Weller Iron Station and I still hear the sound of fingernails scraping down a blackboard when I hear the word Sodder (Do we store computer files in a fodder or the opposite of hotter is codder?) Sorry, I couldn't resist.

    Well done, I watched it end to end. I almost subbed, but I'm too old to be working on cars, my triple carbies and LSD's days are over. But thank you, I enjoyed it.

  14. Ive been using these handy heatshrink combined with solder. Its a piece of heat shrink with a ring of low temp solder in the center. It makes soldering much faster because you just hold a heat gun on it for 20 seconds and you have a perfect solder and heatshrink all in one stel.

  15. For those who would like to know more about the technicalities of soldering, here's some info from a materials engineer.

    – The best possible solder is 63-37% tin-lead mix ratio. The reason is that at that ratio, tin and lead form a special material that instantly solidifies instead of slowly cooling down and transitioning from liquid to solid over a prolonged time. 60-40 is close enough for most applications.

    – Rosin, or flux as called in the industry, is not only useful for protecting the wires. Flux has 2 main goals: preparing the surfaces to be soldered, and then making sure a proper solder joint forms. This is achieved with ingredients in the flux that slowly creep onto the metal and dissolve any surface impurities like grease and oil. Solder can only join onto unoxidised metal surfaces. It also helps the solder flow onto the material easier. Flux is basicly essential to avoid "cold soldering" – joints that seem soldered but have no physical strength due to surfaces that aren't joint properly. So yeah, always use solder that is pre-fluxed if you want an easy job.

    – If you want to use lead-free solder, get a good high-power iron because you will need it. Lead-free solders require a considerably higher melting temperature and even more heat to keep them molten. Environmentalists are pushing towards these but even well-educated people use Pb solder due to its ease of use.

    – Try to set a good balance in soldering temperature. If your temp is too low, the material will not melt properly, or the iron will get cooled too much by the dissipation of heat in the metals. If it's too much, you will burn the flux and create a mess on the joint. My ideal temp for 60-40 solder is 300-320 °C for heavy gage wires and 280 °C for small electronics. Try to go as high as possible where the flux smokes good but doesn't get immediately burnt on the iron.

    – Regarding ventillation, I always highly suggest the fan facing away from you. If the fan is blowing air towards you, the smoke goes everywhere, and at the same time your soldering iron has to compensate for the cooling effect of the air flow, which might make youre job harder depending on the power of the iron. With the fan facing away from you, the smoke gets captures in the suck of the fan and is pulled away from you, and you save your iron from direct air flow.

    Regarding tool choices, I highly suggest the Jokari Secura wire stripper, it does an impeccable job at quickly stripping even very fine electronics wires. It is also sold as the Felo "red dragon" in the US. It's not even that expensive and will serve you very well. There is absolutely no danger in accidentally cutting into your wires which could happen with the old-fashioned stripper tool.

    Otherwise, Chris does an impeccable job covering this topic.

  16. Bad 8bfo on stripping wire…, DO NOT TWIST THE "OLD FASHIONED" STRIPPER AROUND THE WIRE!!!! This Mark's the wire, makes a gouge nick in the wire and makes it prone to failure and strands can let go and drift into the area and SHORT. Also makes a brittle joint. Use the stripper in one motion. Do not twist around the wire cutter around the wire. If you are not str ooi ng enough to pull the insulation off in one motion, buy an automatic wire stripper!!!!!

  17. Lead Free Solder blows!-John in Texas

  18. You are VERY TALENTED I learned a great deal from you Mr.ChrisFix. I am very grateful for what you do for me and other YouTubers like myself. Thanks ! ! !

  19. Squeeze down on the strippers and twist… always good advice.

  20. "Becauss" "woter"

    God I've never been so angry at an educational video.

  21. Chris fix I tried to smoke the joint but I just got burnt by the solder please tell me what I did wrong

  22. Wholy sheite. Here's me, soldering iron in the right hand, roll of solder in the left hand, and how do you unravel the ever dwindling supply of solder from the roll, in order to keep up with the high rate of usage? Why, I use my 'third hand', which just so happens to be my teeth, and you're telling me it has lead in it? No wonder I perpetually keep such poor health!

  23. Thanks Chrisfix!! I saved a bunch of cash by re soldering my Stratocaster, and my studio headphones! Guitar center tried to way over charge for a couple of small solders. It cost me only $20 for the soldering gun and 20 minutes of time.

  24. you are awesome, well done

  25. Thanks for your video it helps my channel grow and push me
    make more, Good Job

  26. Bro… So thorough. No 2nd guessing, no corny music and no childish punny jokes. Straight forward and educational. Subscribed ✌

  27. I use flax I mean flux flux

  28. Are use flux are use flux

  29. Man you are heating the wire ????you should not put the gun on the wires for so long

  30. I will take (2nd way to Splice wire) the NASA way over any other way to SPLICE wire. LOL

  31. I thought the word “Solder” in the title was said “Sold-der”.

  32. I love to breath in the soldering smoke and rosin. Are you saying that was a mistake ?

  33. Expert Job of explaining how to Solder. I see why you are the BEST…***

  34. WHY GO TO KOLLEGE JUS WATCH ,
    A KRIS FIX VIDEO!!!!!

  35. I read somewhere that today flux is added to most soldering wire so added flux is no longer needed. Is that right?

  36. That copper wire trick for the solder tips is pretty genius, any disadvantages of using the wire instead of the premade tips? I have a bunch of 14/12 gauge copper solid wire laying around, just gotta strip all the insulation off.

  37. Absolutely brilliant video sir.

  38. I had asked the question in one of his videos about Freon and he corrected me and he was very nasty about it. Very unprofessional????????

  39. Lots of good information here. I have found that when stripping wires never go around in a circle, you can score the wires and lose some strands or break the wire when putting a wire nut on a solid strand wire.

    Put the wire in your wire stripper and rock it back and forth while pushing the wire stripper with your thumb.

  40. Quick tip. If you're wiring things and soldering them together use a thin strand solder lead based without flux. Melts faster and in my experience is easier to use. I know flux is good to use but I've only ever needed it for electronic board repair or pipe fittings.

  41. April fools!! LOL

  42. Excellent video. Repeating what others have said but you deserve the praise – this is how instructional you tube videos should be made! Well done!
