Crimping woes

[gazdkw82]

Nearly Everytime iv tried crimping I have really struggled and its really starting to frustrate me.

Today I was trying to crimp a ring crimp to a 2.5mm solid conductor for attaching to a piranha earth ring on a SWA gland. Tried 3 times and it just wasnt a good connection. Tried different positions on the crimp and still no good.

Is it something I'm doing? Is it my crimper? Is it the crimps? Really starting to get to me now as in reality it's not exactly a difficult thing to do

Another vote for the Knipex crimpers. I have several sets for different applications. I've found in the past that the cheap ones just dont cut the mustard. Good quality tools are an investment.

that's why i have a £20 hammer for the high-tech. bits.and a £5.99 b&q one for wrecking floorboards.

Getting good results when crimping solid conductors can be problematic.

• Get a decent crimper that has adjustments built into it for calibration...and yes, they're expensive but the cheap crimpers are generally hit and miss.
• Try to use crimps by the same manufacturer that made the crimper.
• Read the data sheet to make sure the crimp you're using is rated for solid core wires.
• Uninsulated crimps have always given me a better result with solid core, we just insulate accordingly afterwards with some heat shrink if necessary. I'm guessing this is because the plastic insulation can become a variable within the crimping process because of softening in warmer ambient temperatures etc

Are you using yellow crimps on 2.5mm cable? If so, you need to change them to blue. You will never get a good crimp connection with yellow to 2.5

you will if you overlap the conductors.

Was actually using a red crimp

Don't follow

2.5 cable in a 1,5 crimp. follow. use the right six=z crimp, hit with a hammer, job done. applxapies i am pi$$$$$ed

Red is for conductors up to 1.0, blue is for 1.5 and 2.5, yellow for 4 and 6.

That was the first thing I tried. Didn't work. Hence why I then ended up trying it on the red
