If too tight for sand paper, a thin metal tip or small blade can also work.Ĥ-Point away the torch and simultaneously touch to both of the surfaces to be soldered with the tip of the soldering wire and push it into the gap, trying to melt it with the heat of the metals as it goes in. The sequence of soldering for me is as follows ġ-Clean the area of solder, by sand paper if possible.
It melts and drips to the ground, just at the moment it gets a little close to the flame, without even touching the point to be soldered. I've also tested the electronics soldering wire, it is too thin. I've bought soldering wire a bit thicker than electronics soldering wires. But I guess it is better this way, as it makes making mistakes a bit more difficult also. The soldering took a bit long as even this torch is a bit weak for this kind of job.
So something strong is needed.Ī hand type torch did the job for me. Other types of flameless soldering irons, guns etc would most probably be too weak as the areas & parts to solder are big and the instrument itself also acts like a radiator, taking heat away from the point being soldered. The key to this kind of soldering is to be careful and slow as you'll be working with a powerful flame.
