Soldering Two Pieces of Broken Pot Metal/Zinc Die Cast at 350º F

127 Repair a broken pot metal or zinc die cast table leg using Super Alloy 1 and a propane torch.

This piece is an antique heirloom that was passed down for generations. The woman who requested the repair was quite upset when her husband fell on the table and broke its leg.

The leg is very heavy so we heated the part much longer than you would if it was smaller or thinner. We heated the inside or backside of the table leg to build up the solder. Because the part is broken in two, we need to flip leg over and repair the other side.

When heating the opposite side we were in danger of loosening the solder already in place. We packed the area with MuggyWeld HEAT FREEZE HEAT PASTE to stop the heat transfer. This unique product saved us time and headaches as we would have been playing the game of soldering one side and then the other.


  •  Always use adequate HEAT FREEZE HEAT PASTE to ensure your part is fully protected.
  • Always allow your part to cool completely before removing the HEAT FREEZE HEAT PASTE for your safety and the safety of your part.
  • Keep HEAT FREEZE HEAT PASTE clean to ensure long life of the product
  • For best results, occasionally add water to HEAT FREEZE HEAT PASTE as necessary to keep moist.
  • Allow adequate space between HEAT FREEZE HEAT PASTE and the area to be welded.  HEAT FREEZE HEAT PASTE works so well it can absorb the heat from the area needing to be repaired.
  • Wash hands after handling HEAT FREEZE HEAT PASTE or use gloves to apply.
