#4 Bond Jumper Sleeve Only

thermOweld® molds designed for larger cable sizes can be used on smaller diameter cables if copper adapter sleeves or shim stock are utilized. The copper shim stock, .0108” x 1-1/2” x 3”, is normally wrapped around cable until the diameter is about equal to the cable opening. A tight fit is not necessary as the shim stock will unwrap slightly and prevent leakage of weld metal.

The copper adapter sleeve slides onto the exposed conductor of the cable you are looking at completing an exothermic connection with. The sleeve helps the copper wire fit properly with the mold to allow the exothermic process to work at its optimal performance.
