This video demonstrates how to solder copper tubing to copper plate with Super Alloy 1 rod and flux kit and a propane torch.
Copper is an inexpensive metal used in many industries due to its high thermal and electrical conductivity, corrosion resistance, and malleability. Due to these favorable qualities, copper is an ideal choice for air conditioning lines and tubing, plumbing, fire sprinkler systems, and natural gas lines.
While there are many copper solder rods available on the market, Super Alloy 1 multi-metal solder and flux kit has some unique qualities. This one solder bonds copper as well as aluminum, pot metal, stainless, galvanized metals and more–individually or in any combination. And Super Alloy 1 can be applied with nearly any heat source, making this copper tubing solder quick and easy for the average DIYer. But wait, there’s more!
Super Alloy 1 is a solder kit that contains solder rods and a bottle of liquid flux. The flux is key.
Flux allows the molten metal to flow and bond more efficiently, and this particular flux acts as a visual temperature guide–it transforms from golden colored to root beer brown when the parent metal (copper) has reached the 350°F working temperature.
To solder copper tubing, first pre-clean the copper with sandpaper or a similar abrasive
Liberally apply flux to the joint between the copper tubing and copper plate.
Next, heat the parent metal until the flux begins to bubble and turns brown, indicating that the copper tubing is ready for the solder rod.
Apply the rod, continuing to move the torch to avoid overheating the copper tubing.
When finished, allow the copper tubing to cool, then rinse off the flux off with water and a wire brush.
