Is it still ok if u don't sauder the wires.

@Velvet-Iris 9 месяцев назад

Thx for the video man. The instructions were simple. Would it work tho on Washing machine cable, especially burnt?

I would recommend cutting the inner wires at different lengths so that each joint is at a slightly different place.

Is this so that the temperature is regulated more?

@gussi123 4 года назад

@@scaler1817 So there isn't a big lump in the middle from each part laying on each other. More importantly, if by chance the heat shrink that was placed on each individual joint were to tear, being at different lengths there wouldn't be a short.. Also there is less chance of tearing if they aren't stacked on top of each other grinding away and through the insulation/heatshrink...

What I did, was just cut the six odd feet of cord and replace the receptacle. I used an Eagle 1-15 receptacle - it looks like a little yellow barrel and properly fits into the; trimmer/weed whacker/leaf blower since it has no ground slot. I used the six odd foot cord for a switched extension box for my electric drill. This is a really great video, you have here. It really makes more sense since most people don't tinker with things like me. Also, wow that trimmer looks hella dangerous, looks like a reliable old Black and Decker. :3

So many people make cold joints that will fail. I would recommend butt splices. I've never had one fail after years. Otherwise the same method with the shrink tube. I always keep an assortment of sizes for different jobs. Having been an electrician for forty years I've worked on a lot of older solder joints and they can last longer than the wire but as I said many people don't do a good solder joint and I prefer the butt splice method myself even though I have the solder equipment. If it's a long cord with the damage in the middle I'd simply put a male cord cap on one and a female on the other essentially making two cords. That's the only acceptable method with osha inspections. And for a senior it's often a pain having to deal with say a hundred foot cord. Use a short cord when needed and two for a longer distance.

I tried repairing a 12 gauge cord on a Tablesaw and couldn’t wrap the wires so had to push them together. The second problem was holding them while soldering.I recommend buying a little articulated clamp designed for this. The third and most important issue was a hot or powerful enough iron. I used a small iron like yours on the first attempt with no luck. Bought a 30 watt and still didn’t work. Other videos recommend 60 watts or higher for 12 gauge wire. Also rosin base flux and the right size and kind of solder. Some contain acid which can deteriorate the repair over time. Still a great video.

@user-xn9rf2lv5p 2 года назад

yes how do you replace a male or female end connector? thanks

@bbingtube 9 месяцев назад

Pro Tip: Slice the outer cord 3in in line instead of removing it to expose the wires, just fold it back out of the way. You can then cover the repaired wires with it and not have that bumpy lumpy repair and get extra insulation to boot.

@AmplifyDIY 9 месяцев назад

As long as you still cover the entire repair with heat shrink, and preferably the kind with glue in it, this is a great idea. Thanks!

@AmplifyDIY 4 года назад

If you are VERY careful you can use a simple lighter to shrink the tubing rather than a heat gun. Just hold the heat shrink over the top of the flame, about 2-3 inches above it. Go slowly, and be very careful that you don't get the heat shrink tubing too hot (it'll start to melt) or let it catch fire. Good luck!

Or just close it off? Please any advice appreciated

@AmplifyDIY 3 года назад

If the damage is near the end, it’s usually best to simply replace the end with a new one. New ends are cheap and plentiful at your local hardware store. Hair dryers will typically not get hot enough to activate heat shrink. You can use a lighter, but be VERY careful. Good luck!

Sorry for the late reply! Hopefully you have repaired your extension cord already, but if not - I like the 3:1 ratio shrink wrap, with adhesive lining.

on the soldier iron it has a temp gauage that can be adjusted - what is the temp to fix a wires on an extension cord?

@mrtacos705 3 года назад

Please do the end connector video, I have a test...

@rakmobrakmob749 2 года назад

Thanks for the video. Could this also be used for a long extension cable which risks to get wet? (e.g. lawnmower cable, pressure jet washer cable, or underground cable for garden lights, etc)? An idea of the waterproof rating it provides (e.g. IP68, IP67, etc) would also be very useful. Thanks.

@AmplifyDIY 2 года назад

Hi Rakmob - In wet locations, I would tend not to trust a repair like this... however: It's really a question of risk vs cost. For example, if I am going to be burying a cable and if it fails I'll have to go through the trouble of digging it back up, I would not put in a repaired cable. However, on something like a lawnmower I'd be more willing to trust a repaired cable, as if it ever fails dealing with fixing it is pretty simple. If you do decide to use a repair like this somewhere like that, I strongly encourage you to use heat shrink that includes hot glue on the inside, which will make a nice watertight seal. If you can't find heat shrink that already has glue on it, then you can always cover all your joints with actual hot glue first, then when you put heat shrink over them it'll do the same thing. Good luck!

@rakmobrakmob749 2 года назад

Unfortunately, the only other way to deal with this would be by wrapping it in electrical tape... which is a pretty bad idea. It won't last, and is a sketchy way to do the repair. Cutting the whole cord and re-sheathing with durable heat shrink is the only way I recommend doing it. Good luck!

@porfiriodiaz4552 2 года назад

Can this method be used to double or tripple the length of the extension cord by combining them?

@AmplifyDIY 2 года назад

You can ... but I don't recommend it. Extension cords are generally only manufactured to be the maximum length that their internal conductors will allow at the rated amperage. So be careful, and pay attention to the load you are putting on the extension cord. The longer the cord, the more resistance. Extra resistance causes more current draw, more heat, tripped breakers, and in extreme cases can lead to fire etc.

@bobs.1872 Год назад

Only 1 thing; I would test it before doing the final shrink although not that necessary if you soldered properly.

@porfiriodiaz4552 2 года назад

Can you add silicone under the last shrink wrap to make it water proof?

@AmplifyDIY 2 года назад

Hi Porfirio - I did not, but you can. If you are looking for a water-tight seal, look for heat shrink that has hot glue in it already. As it shrinks it melts the glue which then makes a water-tight seal. Good luck!
