Does anyone have experience with the low temperature welding/soldering rods that are available?

Thanks in advance

Yes I was very impressed  with this similar  (probably same guy )  product that was demonstrated at the Bath & West restoration show last Nov , that looked very easy to undertake .I thought the cost was around £30 mtr , on reflect , I wish I made a purchase .

I bought some rods off ebay, but not had time to play since. My research indicates that 3rd generation aluminium solder type products are the ones to buy, I may remember to share my results once I get time to play, if I can still locate the broken bits of alloy off my lister Lt1 engine cover....

I've used Lumiweld rods with great success on lots of jobs.

The key to getting a good bond is to get the workpiece itself hot enough so that the filler metal melts when it touches the job rather than just melting in the flame. If the metal itself is not hot enough the filler metal just stays on the surface and scrapes off afterwards.

I welded this filler neck into my Moto Guzzi rocker cover using Lumiweld.

Thanks for the input guys I have ordered some to give it a try. Will test it out first on a bit of scrap.
