The advert shows what looks like an electric heat gun being used. I have one of those and with a bit of fettling I could adapt a nozzle to direct the heat more accurately.

I imagine the plastic would melt with a naked flame?

A butane lighter is about 3000 degrees. I used to have a heat gun one with the "curled up" bit like in this photo. Easy enough to make and secure with a jubilee clip to the blower..

3000 degrees. That's Impressive. You have some serious ligters down your way. That's more than enough to melt steel. Almost enough to melt titanium. So should be enough for soldering i would think Smile

(I just ordered some connectors - I'll let you know!).


My order arrived! I tested one with a cig lighter & it seems to work fine.
However, there are several videos on YouTube & it's worth watching 2 or 3 to see varying, though all positive, opinions.

I have also bought some. Although it gave the impression that it was British (Union Jack displayed) they are in fact made in China.

I obviously intend to use them for the car wiring but today I wanted to join a wire to an outside light (LED). Is there any reason why I should not use one of these for 230 volts?

Ray, it should be fine, mains lighting is normally only 2amp, for a given amperage the lower the voltage the thicker the wire

Being Chinese, I doubt they have any ratings, as Alan mentions they won't have to carry high currents (with a led lamp), so the concern would be is the insulation good for a higher voltage? Certainly the ones from RS are rated up to 1KV, I expect these will be similar.

They won't have an official IP rating, but are probably good to meet IP64.

All that said, for 240v jobs I would stick to Wago's or the like, especially if connecting solid wire to stranded (common when fitting lamps) . They are cheap, very quick and easy to use, more reliable than screw block terminals and importantly designed for the job.

If you have not used them before this video gives a good overview:

The Wago 224's are specifically designed for lighting where solid cable meets stranded. https://youtu.be/y98v7NvuCVw
