RL33 - Hammer-On Copper Cable Lug for #1 and #2 Welding Cable

High-Conductivity Cast Copper Termination

The RL33 Hammer-On Cable Lug is a robust solution designed for the efficient termination of welding power cables. Engineered to accommodate #1 and #2 AWG cable sizes, this lug is manufactured from heavy cast copper, a material chosen for its superior electrical conductivity and thermal properties. In high-amperage welding applications, minimizing resistance at connection points is critical to maintaining arc stability and preventing overheating. The dense copper structure of this lug ensures an efficient current transfer from the power source to the electrode holder or ground clamp, reducing voltage drop across the connection.

Tool-Free Installation Design

One of the primary technical advantages of the RL33 is its installation mechanism. Unlike standard compression lugs that require hydraulic crimpers or large leverage tools, this lug utilizes a mechanical impact design. The barrel of the lug is designed to be deformed securely around the stripped cable strands using a simple hammer strike. This feature makes it an indispensable component for maintenance, repair, and operations (MRO) environments where specialized tooling may not be immediately available. The resulting bond is mechanically sound and resistant to the vibration and movement typical in industrial welding environments.

Durability and Performance

Built to withstand the rigors of heavy industrial use, the cast copper body resists deformation under thermal stress. The lug provides a substantial contact surface area for bolting to machine studs or grounding points, further ensuring low-resistance connectivity. While designed for ease of installation, the connection quality rivals that of standard crimped terminals when installed correctly, making it suitable for both temporary field repairs and permanent shop setups. It is an essential component for maintaining the integrity of the secondary welding circuit.
