Eumig Bulb holder question

#1 by Tom Photiou , Sat Mar 05, 2016 2:32 pm

Hello all, Quick question, we need to replace our Bulb holder on our Eumig 802, quite common i believe, my simple question to all electrical experts is simple,
is it ok to join the new bulb holder wires using small block connectors or should they be soldered together. Thank you inadvance

I am not one to ask about this, but for myself, I'd solder and use some electrical tape to cover the solders. And solder them at different lengths, so the are sure not to touch, if the tape should fall off by any chance. Or the Scotch locks could do the job too

Tom, the wires on these connectors are not easy to solder, they have a heat resistant coating or what looks like a fibre glass material because of the heat, the wires will be ok
in block connector, twist the wire on each end to stop it being crushed down when you clamp them in the block connector, should have a brass feral crimped on the end really
this stops them arcing during prolonged use. Get a picture up here Tom, will clarify it to us all, I can amend any advice for you.

Or boot laced ferrules Tom as said already on this one.

If you starting again Tom, so to speak, the braided cable need not effect your decision on whether to use a connecting block or not.

If you want to fit a similar heat protection sheath, look to use a length of sleeve sheath braid which is readily available.

Thanks all, i shall pop some images on here tomorrow so you can see what i have done & perhaps let me have your verdicts. I need to get some A231 100w bulbs now, unfortunately i use to get these from P Foster as there were a pretty good price.

Good luck with it pal, I'm sure all will be fine.

Hi all, thank you for the advice, here is what i have done for this machine, will definatly try the full soldering job on the next machine but to get this one up and running again we did a quick connection repair using the Van Ek bulb holders, have to say these are very good and seem well put together and quality is perfect.

Indeed, my soldering skills leave a lot to be desired, so the "blocks" are infinitely a better bet. Tom, well done.

many thanks Hugh, bit of a dilemma though, the poxy bulb im trying doesn't work, the filament looks OK, i have ordered 4 new bulbs so that will be the test for me, unfortunately i do not have multimeter's or anything so i cant test to see if there is power to the bulb until i get the new ones which will obviously give me my answer. I dont know if these machines have a fuse for the bulb anywhere but i dont think they do.. Funny isn't it, I can take an Elmo to bits,(within reason), but a simple old Eumig i have hardly ever done anything on. I also dont have any service books for them.

Just try it with one out of your Elmo's Tom, at least then you'll know if it is working or not.

I'd be highly surprised if this heavy current circuit wasn't protected by a fuse. It is on every machine I've ever seen except for toy projectors.

If the lamp circuit is open, you cannot do any harm to a known good existing lamp, so either way, your lamp will remain good to put back into your Elmo.

Just don't bend the pins more than necessary if you do try this. But just as a quick check, all should be fine if you don't want to wait.

There is a fair sized amount (I think around a dozen) of these lamps up for grabs right now on e bay Tom. £20 starting price, no bids as yet when I last looked and to top it all off... Osram Xenophot A1 231's at that!

Unrepeatable starting price I'd say for a dozen brand new. Worth a watch mate!

Sorry Tom, it's only 9 I've just seen, but still £20.... worth a look I'd say.
