What is the best way to connect wires and extend igniters?

    When wiring in series, or extending ignitor length with shooting wire etc, what are people preferred ways of reliably joining the cables?
    I see specialist pyro connectors are available, I guess choc blocks would be cheaper and do the same job, (though probably a bit tedious) or does twisting the wires (and taping?) work just fine?

    1st year remote firing so trying to do my homework early!

    Twist and tape works just fine. I like to use jelly connectors for my personal shows. Ive also seen reusable wago connectors used too.

    It was my first time remote firing a few weeks ago. I’d brought the pyro connectors with the pliers tried a few when I was testing crimped one that didn’t catch the wires at all. It was probably my error but I gave up with them and just twisted and taped had no problems.

    It was 30 degrees and dry though not sure what would be best on a damp November day.....

    Interesting - previous posts have suggested the gel connectors (and the proper pliers) are the way to go, as the connection is secure and waterproof. It's also quicker.

    Any professionals want to chip in on this as you do this week in and week out?

    Twist and tape is fine. When I first started out doing pro shows I asked the senior about twisted connections and damp (it was raining ) and he said as it was DC the damp would make no difference .

    Low voltage DC wires you could sit in a puddle and it would still work, water is actually quite resistive at low voltage so a twisted wire connection would still be far less resistive even if open to the elements. I am not suggesting we should all shoot in puddles mind.

    In terms of the gel connectors.....sound expensive for my penny pinching :p

    Actually @nickjee I'll spin this out into a new thread as it's a great question to ask in its own right :)

    I've been discouraged from using gel connectors by my display company on the basis of speed, cost and environmental impact.
    But I prefer them myself....

    I guess the main thing is to stop any wires shorting against each other. I went along to one pro display there was very few wires to connect together but they were just twisted together and then twisted into a loop of the plastic coated igniter no tape at all.

    Twist and tape, but I am probably going to switch to gel connectors for speed and convenience.

    Twist n tape all day long
    Besides , that gel is horrid all over your fingers if you have lots to connect !!!

    Cheers Pete, and thanks everyone else for their knowledge on the subject!!

    First time anyone has mentioned that.
    That’s good to know,
    So if you had lots to do in the prospect of autumnal weather and time would you still twist and tape, or is there another cheap, easy crimp apart from Gel connectors ?

    Twist and tape for ease if you need to extend.

    Ok so I’v changed my mind back to twist, that is quick and easy. It’s the taping I find annoying and time consuming. So I twist the wires fold back on themselves and re twist,so they won’t easily pull apart when I step and trip over them later on :) then tape each separate wire, then tape both now insulated wires together.Is this total unnecessary over kill ?( they certainly don’t pull apart even when you want them to )
    And reading through the thread do you need to tape at all. I always assumed you would have to water proof wire connections, rain , wet grass , electrics water don’t mix etc.
    Very interested to know what others do regarding the taping side ??

    You should tape. You can be caught out by shorting the two sets of wires out on themselves. It does also protect from the weather which may or may not be important lol, it would also stop the wires oxidizing and becoming resistive depending on time scales.

  17. Me personally twist each together, tape individually only to stop a short. The key thing if you've got lots to do is cut/break/bite lots of small strips and stick them on your leg. Then each joint doesn't include fiddling around with the roll of tape. Then knot the cable to stop the tripping issue.
    Water dont make no difference to the joints.

    Watched from 4.33, until the end , completely missed the point, when back to 4.20- 4.30 and yes that most definitely answers my question.
    That hurts my brain, but great to know.
    Water has 0 effect on connections ,fascinating .
    Don’t think I’v got the balls to put my firestorm in a tank of water and see if it still fires, but I will put a pair of twisted wires in water and see if it still fires at the end. I tape not just to insulate to prevent shorting but mainly to keep water and damp out, which I now know is not necessary.
    Thank you, that simple bit of info has educated me and saved me some time .
    The true answer I think to all this, is buy more field units, then wouldn’t need to extend so many :) but I need to stop buying pyro and invest in more kit !!

    Twist and tape, but tie wires together so that joint isn't under stress when the muppet trips over it in the dark! So figure of 8 knot both pairs of wires together, then twist and tape the ends. Don't tape them together as it makes it harder to see a fault visually, tape individually.

    YMMV, but I've done it this way for a lot of years and it's done me okay!
