GOLDWELD CR2 Exothermic Welding Mold – T-Type Cable-to-Ground-Rod Connection

Video Products

Product Overview

The GOLDWELD CR2 Exothermic Welding Mold is designed to create permanent, highly conductive T-type connections between copper conductors in grounding and lightning protection systems.

Manufactured from high-quality graphite, the CR2 mold offers excellent thermal resistance, dimensional stability, and reliable performance across repeated welding operations.

Technical Specifications

Key Features & Benefits

• Permanent Connection: Creates a metallurgical bond between copper conductors without mechanical fastening.
• Excellent Electrical Conductivity: Provides a low-resistance current path suitable for grounding and lightning protection applications.
• Long-Term Reliability: Properly executed welds resist loosening and maintain stable electrical performance over time.
• Reusable Graphite Mold: Supports approximately 70–100 welding cycles with proper handling and maintenance.
• Efficient Installation: Designed for consistent welding results and straightforward field operation.
• Cost-Effective Solution: Reusable molds help reduce installation costs across multiple connections.

Compatible Exothermic Welding Materials & Accessories

GOLDWELD provides a comprehensive range of exothermic welding materials and accessories, including:

• Welding Powder: Available in 45g, 65g, 90g, 115g, 150g, 200g, and 250g sizes.
• Mold Handle Clamp: Secures the graphite mold during welding.
• Metal Retaining Disc: Holds the welding material inside the crucible before ignition.
• Ignition Tools: Used to initiate the exothermic reaction.
• Cleaning Tools: Brushes and accessories for mold maintenance.
• Sealing Compound: Helps prevent molten metal leakage where required.

Note: The required welding powder charge and compatible accessories must be selected according to the specific mold model and conductor dimensions.

Installation Guide

1. Inspect: Check the graphite mold for damage and verify compatibility with the conductors.
2. Clean & Dry: Remove dirt, oxidation, and moisture from the mold and copper conductors. Preheat where necessary.
3. Position: Place the conductors into the designated mold cavities and secure the mold with the handle clamp.
4. Load: Install the retaining disc and add the specified quantity of welding powder and ignition material according to the manufacturer’s instructions.
5. Ignite: Close the mold lid and initiate the welding reaction using the approved ignition method.
6. Cool & Inspect: Allow the weld to solidify and cool sufficiently before opening the mold. Inspect the completed connection and clean the mold before reuse.

Safety Notice: Exothermic welding involves molten metal and extremely high temperatures. Only trained personnel should perform welding operations using appropriate personal protective equipment and approved procedures.
