For good tin welding, it will be necessary to have a good welder suitable for the type of welding we have to make. There are several types:

	Fine-fine precision electric welder, suitable for small wire wires or electronic cards
	Pistol electric welder, effective for welding small and medium size electrical wires
	Electric bender welder for wide welding
	Gas tin welder, useful in case of no electric current or near vicinity.

We will then have to clean the surfaces to be welded by applying the special "strong paste" which serves to deoxidize the surface making welding more adherent.

In the case of electric wires it will be useful to tincture (apply with the tin welder) the cable before proceeding with the actual welding.

Once this is done, we can combine the two parts, for example the two cables, placing them parallel and applying them through the additional paver welder.

To make the weld more resistant do not blow on the welded part.

Let's remember to protect the junction with the insulating tape or insert a shrink tube before welding.

The tube placed on the junction will then be reduced by the use of a flame. In this way the junction will remain perfectly isolated.
