Cadweld Plus
The ultimate high quality connection that will never loosen, corrode, or increase with resistance.
Introduced in 1938, CADWELD exothermic connections quickly became recognised as a permanent and reliable solution for rail, cathodic protection, power, and grounding applications. Decades of continuous development have helped establish the system as an industry standard for creating molecular bonds that will not loosen, corrode, or increase in resistance over time.
CADWELD PLUS builds on this proven technology by simplifying the exothermic welding process. The system features an integrated welding material package that eliminates the need for separate starting materials, reducing installation time and improving ease of use in the field.
Each tamper-proof welding material package contains a precisely measured quantity of welding alloy and an integrated ignition source housed within a durable steel cup. Compatible with all standard CADWELD molds, including CADWELD MULTI, the package is electronically ignited using a simple battery-powered control unit and lead assembly.
The result is a safer, faster, and more efficient installation process while maintaining the high quality, permanent electrical connections that CADWELD is known for worldwide.
Features & benefits

- Electronic Control Unit
- Replaceable 1.8m Control Unit Lead
Cadweld Plus connections offer all the benefits of:
Current carrying capacity equal to or greater than that of the conductor
Withstand repeated fault currents without failing during operation
Permanent, molecular bond that will not loosen or corrode, resulting in a connection with a lifetime equal to that of the installation
Join copper to copper, copper to galvanized or plain steel, copper to copper clad steel, copper to bronze/ brass/stainless steel, steel to steel, etc.
No external power or heat source required
Quality Assurance Inspection is easy and visual
Minimal installation training required
Exceeds requirements of “IEEE® Std 837- Std. for Qualifying Permanent Connections Used in Substation Grounding”
The Cadweld Plus System
Consists of a tamper proof, disposable, moisture- resistant welding material cup. The welding material, disk and ignition source are incorporated into the self-contained package
Long shelf life
Completes welds at distances of up to 1.8m
Requires minimum components – no starting material, no disks, no flint igniters
Easy to handle, store and transport – by air, land or sea in unlimited quantities
Reduces installation time by 20%
Has color-coded welding material containers – by size and alloy type – for easy identification
Has electronic ignition with a CE/UL battery powered controller box that is designed for 600 connections with one set of 8 standard AA batteries (included) – requiring no special batteries or chargers
Designed for use in standard CADWELD molds including CADWELD MULTI
Installation is easy
4 simple steps for permanently welded electrical connections
1. Insert CADWELD PLUS cup into mold (may require use of a cover/baffle).
2. Attach control unit termination clip to ignition strip.
3. Flick up and hold the control unit button. Wait until ignition occurs, then release pressure from the button.
4. Open the mold and remove the expended steel cup – no special disposal required.
CADWELD PLUS Control Unit initiates the reaction of the metal crucible. The standard unit includes a 6-foot (1.8m) high temperature control unit lead. The lead attaches to the ignition strip using a custom made, purpose-designed termination clip.
After the termination clip is installed on the ignition strip, the installer pushes and holds the ignition button to start a charging and discharging sequence. Within a few seconds the control unit sends a predetermined voltage to the ignition strip and the reaction is initiated.
