A 100W soldering iron can deliver more heating power than a 40W model, but that does not necessarily mean it will solder faster in every situation. Soldering speed depends on the amount of heat that needs to be transferred to the workpiece and the tip's ability to maintain its temperature when it comes into contact with a thermal load.

An improperly crimped MC4 connector can quietly persist for months before a problem manifests. There are no sparks or sounds only a nearby contact point that gradually builds up heat day by day, until the temperature exceeds the insulation's thermal limit
