Leads and lugs

admin

I see that lugs are mostly crimped and not soldered. Is it because the joints get that hot or another reason? 400 F seems a bit warm under normal working conditions. I would think solder would give a better connection.
Reply:I don't know the 'real answer' but...a) The joints don't get hot enough to melt solder ~400Fb) Yes solder would give a better connectionc) Solder would also prevent the oxidation & corrosion of the individual wire standsIt would seem to me that a crimped joint (mechanical), followed by soldering would be best.On the other hand, many 'connectors' are constructed to be tightened with Allen screws.  However, unlike lugs, those connector joints are designed to be taken apart from time to time.IMORick V 1 Airco Heliwelder 3A/DDR3 CTC 70/90 amp Stick/Tig Inverters in Parallel1 Lincoln MIG PAK 151 Oxy-Acet
Reply:I used to solder every one. I have, one by one, cut the solder joints off and now use the ball screw joints, or the crimped lugs. The reason is that the soldered joints have all failed over time and created a high resistance joint, which then gets hotter, and hotter, the worse it gets. I don't know why they fail like that, but they all have. Stick with the crimps and the ball screws.
