DRoberts Posted October 5, 2014 Share Posted October 5, 2014 I tried soldering some copper together for the first time tonight and it went horribly. While looking around at different soldering pastes I ran across this thing. Looks like some kind of chemical bonding agent that doesn't require heat. says it sets in 5 seconds. anyone ever use this? Application is on a habaki wedge insert. http://www.acehardware.com/product/index.jsp?productId=2278592 Quote Link to comment Share on other sites More sharing options...
Glenn Posted October 5, 2014 Share Posted October 5, 2014 Size : 50g (For up to 200 welds) for $26 The 2 reviews are a duplicates. Another bottle says 50g bottle makes up to 40 welds for $34 The 2 reviews, one is good the other is bad for the product. Makes you wonder which is right or if there is a difference in the two products. Quote Link to comment Share on other sites More sharing options...
Steve Shimanek Posted October 5, 2014 Share Posted October 5, 2014 I have used that stuff for plumbing, it is basically an epoxy type compound. I personally would not use it on a habaki. Quote Link to comment Share on other sites More sharing options...
RP Coyle Posted October 6, 2014 Share Posted October 6, 2014 When soldering copper you have to clean it... tin it... and go slow in heating. It takes practice...but if you learned to weld, you sure as heck can lear to solder. Quote Link to comment Share on other sites More sharing options...
Steve Sells Posted October 6, 2014 Share Posted October 6, 2014 For habaki I do not solder, I use braizing rod, bretter color match than the silver Quote Link to comment Share on other sites More sharing options...
DRoberts Posted October 6, 2014 Author Share Posted October 6, 2014 my first attempt was with lead based solder, big mistake. bought the 98/2 tin/silver wire with flux paste afterwards. by the 3rd attempt i nailed it. had a little sliver of tin discoloration, will use larger copper wedges in the future to fix.

stan Posted February 14, 2015 Share Posted February 14, 2015 Hi I`m a refrigeration mechanic the best way to weld copper is to braze it with brown tip silver solder(15% silver)no flux required for copper to copper minor cleaning, heat evenly just before red, solder will follow the heat. This can also be used to join copper to brass or steel but for these operation flux and more cleaning up is required. Quote Link to comment Share on other sites More sharing options...
