They had that on Lorry loader cranes, if the main battery connectors were soldered the cable would fail at the point were the solder had stopped flowing into the multi strands.
After that issue was discovered it was crimps all the way.
I have a vague memory that @brightspark tested copper slip with a megger and it was non-conductive just like standard grease, I have overheard people saying its good for battery terminals as well as reducing corrosion it can help with any poor contact problems as electric can flow through the copper.I dont grease any terminal posts or lugs on the welding kit Mr Vark, I am guilty of slapping icopperslip or grease on battery terminal though.In years gone by it was Vaseline but now its whatever is to hand.
When multi strands are to be soldered you shouldn't ever flow solder back up the wires into the insulation there should always be three or four mm not soldered . Having them with solder run back into the insulation is called wicking and not allowed when doing Ministry of Defence work
correct I tested copperslip with a 500v megger and it was a total insulatorI have a vague memory that @brightspark tested copper slip with a megger and it was non-conductive just like standard grease, I have overheard people saying its good for battery terminals as well as reducing corrosion it can help with any poor contact problems as electric can flow through the copper.
That was the issue we had.
But the technical manager insisted we soldered.
But after a series of recalls we went back to crimping.
Sound like bad engineering design or the wrong sort of stranded cables . I'm sure you can imagine 2 x 100 amp 12 v batteries bolted down in a tank or fighting vehicle the battery cables are well clamped to stop vibration problems
Interesting very interesting .don't ever bother soldering welding leads in to lugs the cable cant flex and snaps quite quickly . best crimped and will flex for years . been there done it and got the tee-shirt

They are, the lorry loaders were always a bolt on after thought.
The cables in ARV are secured well to stop board Pongo's playing.
loose to get em out of the way in case the outside tries to get in the inside.What about the cables on sewer pipes and skimmers
Always worth having the bolt on ones handy for the quick and easy "temporary" bodge

Me too, on 2.5mm flex for motors I pull the coloured sleeve off normal crimps, solder them on and cover with heat shrink. Much neater and more secure to my mind, even if soldering stranded cables isn't ideal.
I am not allowed any views now until next month, according to swmbo I have used up my quota of three in the first week of this month.

It’s really a high temperature grease, so great for stuff like manifold bolts, exhaust bolts etc. It’s good as a general purpose grease for anything really, we used to use it a lot in the Navy for anything that would get a hammering by saltwater, though I’m not sure it’s more effective than normal grease for low temp applications to be honest.I have a tin of copperslip, forgot what I bought it for... what do ya'll use it for?
