ALLTEC TerraWeld Exothermic Welding System Manual

The TerraWeld® Exothermic Welding System is a simple, cost-effective and permanent welded connection that uses a high-temperature exothermic reaction and does not require an external heat or power source to create a molecular bond. It's a superior connection method for making permanently copper-to-copper and copper-to-steel electrical connections.

Frequently asked questions

TerraWeld® meets or exceeds UL 467, IEEE 80, 837, and 1100, NFC 15-100, NEC Article 250, National Electrical Safety Code (NESC), and BS 6651.

Dry the conductors with a torch, then clean them with a wire brush to remove all dirt, ash, and oxides. Make sure the conductor surface is clean of all dirt, grime, and oil residue.

A small amount of slag on the surface is typical. If slag covers more than 20% of the connection surface, cut the cable and try to reapply the weld.

Porosity is usually caused by contaminants like water, oil, or dirt in the mold or conductor. A few small pinholes on the surface of the riser are normal. However, the depth of a pinhole should never extend beyond the center of the conductor.
