fouad Posted July 18, 2006 Report Share Posted July 18, 2006 As you know, many devices uses battery packs.Regarding that i face allot of problems inside the battery packs and i solve it by replacing the defective batteries with new ones.The problem is when we solder them by the welder it will not be strong and it takes time to do it. Also the heat of the welding may affect the battery.Is there any project to design a spot welder for batteries ?I Appreciate any informayion about it.thanks.

GreekPIC Posted July 18, 2006 Report Share Posted July 18, 2006 I'm building one too for making gas turbine parts. Check this page out. You can live without the timing circuit, just rewind the transformer, add a footswitch and a fuse.This site should be interesting to you, alsoNikolas Quote Link to comment Share on other sites More sharing options...
