141 How to Solder Zinc Die Cast with Super Alloy 1 Solder and Flux Kit
Another MuggyWeld.com testimonial
I was very impressed with your zinc die cast solder. In my opinion it worked better than I thought possible. After I soldered the zinc die cast pieces together, I intentionally tried to break the solder off and could not do it. I was truly stunned to see how strong this zinc die cast solder was. As you can see in the pics, this was not a large piece of zinc die cast with a large work area–quite the contrary. The zinc die cast table legs had very small surfaces to work with. Following your instructions and videos, anyone can do solder zinc die cast.
To create a heat resistant work area, small pieces of board were soaked in water for about 30 minutes prior to applying solder.
Clean the zinc die cast parts with a wire brush to remove all oxidation, then place on the wet board.
To solder zinc die cast, hold a propane torch perpendicular to the work area. Broadly heat around the part, making sure not to overheat any of the zinc die cast.
Watch the flux–it turns root beer brown when the zinc die cast has reached 350°F. This is an indication it’s time to apply the solder rod.
Heat around the zinc die cast piece with flux, test with solder rod until it begins to flow.
Step away, repeat with additional solder and flux.
Allow repair to air cool.
2 of the 3 legs were broken in the same spot. I used a Dremel tool, handheld file and emory cloth sandpaper to form and finish the solder. I dabbed some gold paint over the solder to help color match the paint of the table legs.
