Solder vs crimp debates pop up on most forums at some point or the other, with strong opinions on each side.
I'd much rather have a mechanical connection with a crimp on high amperage Lugs.
One reason, is that Tin solder is not super conductive.
On a conductivity scale of 1 to 100, 100 being pure copper,
Tin solder scores a 11.9.
Silver solder scores a 16.6
While either crimping or soldering can be done poorly, even a poorly done overcrimp is not going to fail mechanically, but a poorly soldered lug can have the cable pull from the lug. If it is a + cable and touches ground, the insulation will start smoking in under 2 seconds.
The hydraulic crimpers are a great tool to have for occassional use, but the metric dies sizes and different thickness lugs and cables, means one has to take more time to insure a proper crimp, perhaps rotating the crimp in the die and switching dies, stepping down in size.
When one is doing lots of crimps, then the cheap Hydraulic crimper becomes a time consuming liability.
