- A propane torch. If you're only doing small joints for crafts you might be able to get away with smaller crafting torches, but if you're trying to joint long lengths of tubing, appreciate that all that copper acts like a heat sink while you're trying to sweat the joint.
- A flint sparker or other torch-lighting mechanism, if your torch doesn't happen to have a self-ignition system.
- Steel wool. This is used for cleaning up the surface of aged copper tubing and removing oxide to ensure a good joint.
- Plumber's flux and brush. This is important, because without flux the solder will just roll off the copper and not suck into it like it needs to.
The one thing to note in the video is that I interchangeably call the joining alloy solder or lead. Technically it is 40% lead and 60% tin, so I misspoke in the video.
This is all explained in the video, but the steps to sweating a joint are:
- Clean all surfaces to be joined with steel wool until shiny.
- Apply flux to ensure good connection between the copper and solder.
- Join the fittings and apply heat to the whole connection.
- Touch solder to a single point on the joint, and enjoy seeing it magically suck in to make a solid joint.
- Be careful while applying solder that you don't apply too little solder, but once you apply enough, the excess will drip from the bottom of the joint. Try not to burn yourself.
