Hi guys

 

I took a quick look at Metcals online.  Looks like there are quite a  number 

of models available.  What do you recommend?  As a  sub-question, I wonder if 

one is better off crimping connections or  soldering.  Where do you use which?

 

I have always thought of soldered joints as more electrically  reliable.  

However, there is a stiff part where the solder runs up the  wire.  That would 

seem to be more prone to vibrational damage than a  properly crimped joint.  

Thoughts?

The issue of crimp or solder has been discussed at length on this list 

in the past.  If you are interested, I recommend a perusal of the 

archives.  The short answer is that either technology can be used 

successfully, with few exceptions, as long as it is done in a 

craftsmanlike manner.  Both technologies require the use of appropriate 

strain relief, and physical support against vibrational damage.  In 

general, if wire leading to a hardpoint (be it a crimped, or soldered 

joint, or some other rigid, constraining interface) is allowed to wiggle 

around, work hardening of the conductor will take place, and that will 

lead to broken wire.

Regards,



Matt-

  and others under "metcal" search term

  They are for all practical purposes interchangeable

  technologies. One is more expensive and less process

  sensitive but either can produce long-lived joints.

  Much of what's circulated as fact is indeed myth. See:
