Exothermic Molds, Weld Materials, Tools & Supplies

To support operations who have selected Exothermic Welding as their preferred method of conductor connection, Mine Cable Services offers a custom designed series of carbon molds and weld charges sized specifically for flexible stranded copper conductors, as found primarily in SHD-GC mining cables. A user friendly alternative to silver soldering, Exothermic Weld connections create a solid and strong conductor connection during the cable repair process, and is especially valuable when repairing larger sized conductors. The MCS Exothermic Welding process features remotely activated electronic ignition weld charges, creating a safe working distance for cable repair personnel while triggering the exothermic weld charge.
