Thanks for your advice Der Ami

As far as I understand, the most important thing is tinning the barrels and ribs separately, using a strong flux, and then clean VERY well the flux rest so there is no corrosion in the future. Once all places together with the wire, apply the rosin flux, and parts should solder nicely as they have been previously tinned.

I am concerned with the "rosin flux", as I am not sure about what the correct translation into Spanish and I don't know if I will be able to find it locally.

I share interesting videos I have found on the subject:
