Hi, we closed this thread last week. There is also a ton of past searchable info
on APP connectors, crimping vs soldering etc. the list archives. See:

I would agree... I crimp most every thing now. The cost of GOOD crimp tools
are reasonable priced...
BUT, a year or two ago, I found crimp lugs I was using on my ladderline were
making intermittent connections and I was having a difficult time finding the
problem.
The crimp was not working with copper coated steel wire... The steel wire does
not compress. Soldering "might" have helped, but I went to bananna plugs with
screw compression wire connections I can re-tighten as needed...

While many people recommend soldering crimped connectors, such as Anderson
Power Poles, it is not a very good idea. The reason(s) it is neither
required, nor desired, is partially as follows:
1. A PROPERLY crimped connection creates a molecular bond between the
conductor and the connector that is more conductive than soldering.
2. The soldering process causes corrosion because even rosin core solder is
slightly acidic.
3. The solder that flows into or onto the conductor (wire) causes it to
stiffen and increases the probability that vibration or movement will cause
the wire to break at that point.
4. The annealing of the copper wire is altered which also increases the
possibility of wire breakage due to vibration or movement.
It is absolutely necessary that the proper tool be used for the connection
being crimped. If you are going to use a crimped connection it is imperative
that you have a tool that matches the connector. If you do not have the
proper tool then DO NOT use crimped connections.
