Does coating stranded copper wire with solder cause any issues or break any codes?

A "tinned" wire that is done that way by the manufacturer is different than tinning wires at your bench or via a solder pot.

For one thing, the manufactured tinned wire has no lead in the PLATING (co-valent), and said plating is very uniform and very thin.

A tinned wire at the bench has lead in it, IS susceptible to solder creep, and the process is intermetallic, but only when done right.

Placing said wire in a PCB, the proper way to prep the wire is the way you describe. For it to be pre-tinned as it is called. The MAIN reason is so that one can construct the PCB / wire / solder joint connection in the fastest time frame, reducing the likelihood for insulation damage to a minimum. It also increases the odds of constructing a proper solder joint with the highest reliability and least amount of leeching of the solder up the wire, in the case of stranded wire.

The discussion, however, is about whether or not a wire inserted into a crimp type solderless connector should be soldered, and whether or not such a termination preparation is an accepted practice by the industry engineers and manufacturers, not necessarily at the assembler or inspector level.

Cut and paste retard. Do you know that your behavior is considered stupid in Usenet? It is... and they are right too. You be stupid.

You lost the argument before you even began.
