Tinned Copper Wire Soldering

This is an acid free solder that contains a flux in the core of the solder.

Tinned copper wire soldering. I ve had lead free solder in the past that doesn t turn black with my patina but. Also tinned copper is easier to connect because tin is a primary component in solder. Never use solder that contains acid which can damage the wire or its insulation. Tinned copper is better equipped to resist humidity high temperatures and wet environments.

When considering bare copper or tinned copper wiring the environment and cost should heavily dictate which type of wire you choose. To tin a contact on an audio xlr connector hold the iron on the outside of the the contact for a second or two then apply the solder into the cavity of the contact. Acid core solder is intended for use in plumbing applications. If the solder coating doesn t have the right components the patina won t react with it.

Tinning wires before soldering is al. I d suggest trying to find another source for wire or perhaps try a different patina. Tinned copper wire is particularly useful in industrial cranes subways and marine projects where the tin coat makes the wire more resistant to water. 22 gauge wire solid core hookup wire pre tinned pvc coated copper wire of 6 colors black red yellow green blue white 32ft 10m each hook up wire kit from plusivo 4 6 out of 5 stars 549 12 99 12.

Tinned copper wire is also easier to solder to connections as tin is a key element in soldering ensuring all parts of the wire are protected against corrosion. The best solder to use for tinning stranded copper wire is electrical grade rosin core solder. Tinned copper wire is particularly useful in wastewater treatment facilities underground subway systems and projects exposed to excess oil gas or water. The reasoning behind not tinning the wire is if the wire is tinned when the screw closes down on the wire it would break the solder joint and leave an opening within the strands which can be susceptible to vibration loosening and corrosion.

By not tinning the wire you can get a better gas tight joint. The larger the copper core the longer it will take to heat up enough to draw the solder in so use a higher temperature soldering iron for larger cables if you can.
