How to Weld Cable Weights
Cable weights, usually made from lead or other non-alloy metals, are most commonly used in pump systems and other types of mechanical machines. Depending on your specific purpose, a broken cable weight can leave your machine inoperable. Since cable weights are made from soft, non-alloy metals, welding cable weights involves using a gas welder. According to ESAB.com, this process is referred to as "lead burning." Does this Spark an idea?

1
Relocate the machine, motor, device or metal piece where you want to attach the cable weight to your designated welding area. Put on the appropriate protective equipment, which should include welding gloves, a welding mask and some rubber boots.
-
2
Apply some flux both to the piece where you want to attach the cable weight and the cable weight itself. Use a soft-bristled paint brush to do this. Flux is an acidic paste that melts upon heating, which is used to clean metal surfaces before welding.

Light your blow lamp with your desired lighter mechanism, and heat the metal surface. Touch some soft lead solder to the cable weight. Gently rub the blow lamp over the surface of the lead solder until it begins to melt. Grasp the cable weight with a pair of long needle-nose pliers, while still maintaining the heat on the solder with the blow lamp.

Touch the soldered side of the cable weight to the metal piece where it must be attached. Hold it in place for several minutes until the solder has settled and secured the cable weight in place.
