nVent ERICO Cadweld PLUS Exothermic Welding Material 400 F20

The nVent ERICO Cadweld PLUS 400 F20 is a high-performance exothermic welding material engineered for creating permanent, low-resistance electrical connections. This material is specifically designed for use with the Cadweld PLUS system, ensuring consistent and reliable results in grounding and bonding applications. By utilizing an exothermic reaction, it creates a molecular bond that is superior to mechanical or compression connections, offering long-term durability even in demanding industrial environments.

Advantages

The primary advantage of this exothermic welding material is its ability to produce a permanent molecular bond that will not loosen or corrode over time. Because the connection is essentially a solid piece of metal, it maintains excellent electrical conductivity and can withstand high fault currents without failing. The Cadweld PLUS system enhances safety and ease of use by eliminating the need for starting powder and reducing the risk of ignition errors, making it a highly efficient choice for professional electrical contractors.

Suitable for

• Grounding systems in industrial facilities
• Bonding applications for electrical infrastructure
• Lightning protection systems
• Railway and utility grounding connections

When it may not be suitable

This product is not intended for use in environments where open flames or high-heat processes are prohibited by safety regulations. It is also not suitable for joining materials that are incompatible with copper-based exothermic welding or for applications requiring frequent disconnection and reconnection of the joint.

Key specifications

• Material type: Exothermic welding powder
• Compatibility: nVent ERICO Cadweld PLUS system
• Connection type: Permanent molecular bond
• Application: Grounding and bonding

How to use

To use the nVent ERICO Cadweld PLUS 400 F20, ensure the conductors are clean and dry. Place the conductors into the appropriate Cadweld mold and secure the mold with the handle clamp. Insert the welding material into the mold crucible, ensuring the integrated ignition strip is positioned correctly. Connect the electronic control unit to the ignition strip and initiate the welding process from a safe distance. Once the reaction is complete, allow the mold to cool before opening it to reveal the finished connection.

What to consider before purchase

• Verify compatibility with your specific Cadweld mold size
• Ensure you have the required electronic ignition control unit
• Confirm the conductor sizes match the mold specifications
• Check local safety guidelines for exothermic welding procedures

Usage recommendations

Always wear appropriate personal protective equipment, including heat-resistant gloves and eye protection, when performing exothermic welding. Ensure the work area is well-ventilated and free of flammable materials.
