nVent CADDY CDYT320 CADWELD Flint Ignitor

The nVent CADDY CADWELD Flint Ignitor (CDYT320) is the striking tool used to ignite the starting powder inside a CADWELD weld metal cartridge, triggering the exothermic reaction that fuses copper conductors to rebar, ground rods, structural steel, and other grounding and bonding components. It is a purpose-built accessory for the CADWELD exothermic welding process, the molecular welding method widely specified for permanent, high-conductivity electrical grounding and bonding connections in commercial, industrial, utility, and telecommunications installations. Electricians and grounding contractors carry the Flint Ignitor as a standard companion tool alongside CADWELD molds, connectors, and starting material whenever a field weld is being made, and it is commonly stocked as a spare so a crew is never without a way to start a weld on the job site.

Key Features

  • Ignition Function: Generates the spark needed to ignite the starting powder in a CADWELD weld metal cartridge, initiating the exothermic reaction that produces the permanent molecular weld.
  • CADWELD System Compatibility: Designed to work with nVent CADDY CADWELD molds and connections, the exothermic welding system used for grounding and bonding applications.
  • Grounding & Bonding Use: Supports field welding of copper conductors to rebar, ground rods, structural steel, and other grounding electrodes and equipment.
  • Field-Ready Tool: Carried by electricians and grounding crews as the go-to ignition tool for every CADWELD exothermic weld made on site.
  • Spare/Replacement Part: Sold individually as CDYT320 so crews can restock their CADWELD kit without replacing other components.
  • Model CDYT320: Identified under nVent CADDY's CADWELD product line for exothermic welding accessories.

Technical Specifications

  • Refer to manufacturer documentation for complete technical specifications.

Typical Applications

  • Electrical Grounding and Bonding Connections
  • Exothermic Welding of Copper Conductors to Rebar and Ground Rods
  • Structural Steel Grounding Connections
  • Utility and Substation Grounding Systems
  • Telecommunications and Data Center Grounding
  • Commercial and Industrial Electrical Installations

Why nVent CADDY?

nVent CADDY's CADWELD system is a widely specified exothermic welding solution trusted by electricians and grounding contractors for permanent, low-resistance connections that hold up to corrosion and mechanical stress over the life of an installation. The Flint Ignitor is the dependable spark source that starts every CADWELD weld, making it an essential companion tool for any crew running the CADWELD process in the field. Keeping a CDYT320 Flint Ignitor on hand helps ensure grounding and bonding work can proceed without downtime waiting on a replacement ignition source.

nVent CADDY T320 – Frequently Asked Questions

1) What does the nVent CADDY CDYT320 flint ignitor actually do on a CADWELD weld?
The CDYT320 is the striking tool that throws the spark into the starting powder inside a CADWELD weld metal cartridge. That spark kicks off the exothermic reaction which melts the weld metal and fuses copper conductors to rebar, ground rods, structural steel and other grounding components. It is not a consumable weld material and it is not a mold, it is only the ignition source.
2) Will the CDYT320 ignitor work with any CADWELD mold and cartridge I already have?
It is built for the nVent CADDY CADWELD exothermic welding system and works with CADWELD molds and connections generally, because all it does is strike a spark into the cartridge's starting powder. There is no mold-specific sizing to match.
3) Is the flint ignitor included with CADWELD molds, or do I have to order it separately?
The ignitor is sold on its own under model T320, so it is ordered separately from molds, connectors and starting material. Most grounding crews keep a spare in the kit so a lost or worn ignitor doesn't stop a weld on site.
4) Why use exothermic welding instead of a mechanical ground clamp?
An exothermic weld is a permanent molecular bond between the conductor and the electrode, which is why it is specified where a low-resistance connection has to survive corrosion and mechanical stress for the life of the installation. A mechanical clamp can be inspected and removed; a CADWELD connection cannot be undone, so pick it when the spec calls for a permanent grounding connection. The CDYT320 is simply the spark source for that process.
5) Is the CDYT320 a torch or a lighter?
Neither. It is a flint striker, a mechanical spark tool with no fuel and no flame of its own. It produces sparks against the starting material in the cartridge, which is what the CADWELD process is designed to ignite.
6) What grounding connections is the CADWELD process with this ignitor used for?
Field welds made with the CADWELD process cover copper conductors to rebar and ground rods, structural steel grounding, utility and substation grounding systems, telecom and data center grounding, and general commercial and industrial electrical work. The ignitor is used the same way on all of them, it just starts the reaction.
7) What is the correct part number to reorder this CADWELD ignitor?
Order it as nVent CADDY CDYT320, manufacturer part number T320, in the CADWELD line. That is the number to give a distributor when restocking a grounding crew's kit.
