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.
Tinned copper wire soldering.
I ve had lead free solder in the past that doesn t turn black with my patina but.
Acid core solder is intended for use in plumbing applications.
When considering bare copper or tinned copper wiring the environment and cost should heavily dictate which type of wire you choose.
Tinning wires before soldering is al.
Tinned copper is better equipped to resist humidity high temperatures and wet environments.
Tinned copper wire can last up to 10 times longer than its non tinned counterpart and because solder is composed primarily of tin tinned wire is incredibly easy to solder.
If the solder coating doesn t have the right components the patina won t react with it.
By not tinning the wire you can get a better gas tight joint.
Also tinned copper is easier to connect because tin is a primary component in solder.
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.
Tinned copper wire is particularly useful in industrial cranes subways and marine projects where the tin coat makes the wire more resistant to water.
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.

Tinned copper wire is particularly useful in wastewater treatment facilities underground subway systems and projects exposed to excess oil gas or water.
The solder on the pre tinned wire needs to compatible with the patina used.
This is an acid free solder that contains a flux in the core of the solder.
