bubu91220 Posted May 24, 2023 Report Share Posted May 24, 2023 Hello ! What is the ideal solder for old Ar2 3 tweeter rows? I tried kester 44 solder and I get poor results, what would be the ideal glue to glue a partially detached medium grid? Quote Link to comment Share on other sites More sharing options...
ReliaBill Engineer Posted May 25, 2023 Report Share Posted May 25, 2023 I don’t understand the question. Solder? Grids? Tweeter rows? Quote Link to comment Share on other sites More sharing options...
bubu91220 Posted May 25, 2023 Author Report Share Posted May 25, 2023 I note that over time that the lines of the tweeters are very hard to solder, and I wanted to know that it was there ideal solder. the second problem is the midrange grilles which are partially unstuck. I wanted to know what was the ideal glue to glue these grids. Quote Link to comment Share on other sites More sharing options...

E6000 or Gorilla Clear Grip adhesive woks well for the mid screens. Roy Quote Link to comment Share on other sites More sharing options...

RoyC Posted May 26, 2023 Report Share Posted May 26, 2023 The leads are definitely aluminum. If you are in the US I can mail you a piece of the type of solder David described above. Send me a forum PM. Roy Quote Link to comment Share on other sites More sharing options...
bubu91220 Posted May 27, 2023 Author Report Share Posted May 27, 2023 Hello thank you for the information, thank you Roy for your proposal unfortunately I live in France. I managed to find a sample of allusol solder I don't know if you know. Quote Link to comment Share on other sites More sharing options...

I managed to find a sample of allusol solder I don't know if you know. I have never tried that one, which appears to be primarily lead (80%). I use solder similar to the type mentioned in the Google search response posted above by David ("What kind of solder works on aluminum?"). https://www.google.com/search?q=what+kind+of+solder+works+on+aluminum&source=hp&ei=9ONyZNP0DaqhptQP5_yYsAo&iflsig=AOEireoAAAAAZHLyBA9-G94quj8-OITfb_rq6rph_aai&oq=What+kind+of+solder+works+on+aluminum%3F&gs_lcp=Cgdnd3Mtd2l6EAEYADIGCAAQFhAeMggIABCKBRCGAzIICAAQigUQhgMyCAgAEIoFEIYDMggIABCKBRCGA1AAWABg8iFoAHAAeACAAVSIAVSSAQExmAEAoAECoAEB&sclient=gws-wiz Roy Quote Link to comment Share on other sites More sharing options...

Lead is good for plumbing/copper and a few other metals. Quote Link to comment Share on other sites More sharing options...
