Cadweld PLUS Electronic Ignition System by Erico Products

Sealed System Allows Electronic Ignition of Weld Metal. No Flint Gun Required!

System Overview

The ultimate welded connection that will never loosen, corrode or increase in resistance just got BETTER.

CADWELD PLUS is the latest advancement in the continuing evolution of ERICO’s exothermic products. Since it’s development in 1938, CADWELD electrical connections have become recognized as the ultimate connection for rail, cathodic, power and grounding applications. ERICO has established itself as the worldwide conne

ctions leader. CADWELD PLUS continues this tradition of technical leadership.

The revolutionary CADWELD PLUS System is a simplified method of performing exothermically welded electrical connections. The CADWELD PLUS integrated weld metal package has streamlined the installation process by eliminating ignition materials – reducing set up time.

The tamper-proof, integrated weld metal package consists of a steel cup containing CADWELD patented weld metal alloys and ignition source. This new weld metal package is designed for use in all standard CADWELD molds. Once placed in the CADWELD mold, the weld metal is electronically ignited using a simple battery powered control unit with cable lead.


CADWELD® PLUS System Description

  • Consists of a tamper proof, disposable, moisture resistant weld metal cup. The weld metal, disk and ignition source are incorporated into the self-contained package.
  • Virtually unlimited shelf life.
  • Makes welds at distances of up to 6 ft / 1.8 meters/
  • 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 weld metal 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 all standard CADWELD molds including CADWELD MULTI.


CADWELD® PLUS connections offer all the benefits of conventional CADWELD connections:

  • Withstands repeated fault currents without failing during operation.
  • Joins copper to copper, copper to galvanized or plain steel, copper to copper clad steel, copper to bronze/ brass/stainless steel, steel to steel, etc.
  • Current carrying capacity equal to that of the conductor.
  • Permanent, molecular bond that will not loosen or corrode, resulting in a connection with a lifetime equal to that of the installation.
  • No external power or heat source required.
  • Quality Assurance Inspection is easy and visual.
  • Minimal installation training required.
The CADWELD molecular bond will last the lifetime of the conductors.

CADWELD PLUS Accessories

Our latest innovation, the nVent ERICO Cadweld Plus Impulse Exothermic Welding Control Unit, brings you the highest level of flexibility and ease of use of any of our ignition systems. Precision engineered, the control unit lets you choose your power source: from off-the-shelf AA-batteries to the rechargeable Lithium-Ion packs you have on your job site.

Why should you choose our latest ignition system? Safety, Power, and Ease-of-Use.



  • Enhanced power tool style grip is ergonomic and easy to hold
  • Self-closing trigger guard prevents accidental ignition, providing added safety
  • LED ignition counter provides instant feedback on the timing of the ignition and is visibile in sunny outdoor conditions
  • Five second delay in ignition is a safety feature to allow the user to stop ignition, if necessary
  • Battery life indicator integrated into the unit for real-time updates on battery life; compatible with both AA and rechargeable batteries
  • Includes AA alkaline batteries to power approximately 600 connections
  • Rechargeable batteries from Milwaukee® or DEWALT® can be used to power approximately 1500 connections using a 4Ah battery
  • Battery adapters available for use with either Milwaukee® or DEWALT® rechargeable batteries (sold separately)
  • High temperature lead with single molded insert into the unit keeps the most-often replaced component of ignition systems more securely attached and reliable
  • Easy-to-use alligator clip design of the termination clearly shows a positive connection in the viewing window

B323N2 Magnetic Hold-Down Assembly

  • Once attached to the mold handle, the B323N2 securely holds the mold to large, flat or slightly curved horizontal steel surfaces during the connection process.
  • Powerful welding magnet (50 lb rating) securely positions mold during connection process.
    Helps with mold stability to reduce the chance of weld metal leakage.
  • Quickly and easily attaches to “A” price key hold-down molds (new or retrofit).
  • Ideal when used with CADWELD PLUS to allow for full extension of control unit lead.
