BER40B - Bernard 40B Shortstub Screw-Type Electrode Holder 400A

Technical Overview of the Bernard 40B Shortstub

The Bernard 40B Shortstub Electrode Holder is a premier choice for industrial Stick (SMAW) welding, engineered to handle high-amperage applications up to 400 Amps. Distinguished by its proprietary Shortstub design, this holder utilizes a screw-type clamping mechanism rather than the traditional spring-loaded tong lever. This design choice ensures a significantly higher contact pressure between the holder and the electrode, resulting in superior electrical conductivity and reduced heat buildup at the connection point.

Constructed with a durable copper alloy body and a high-impact, heat-resistant insulation, the 40B is built to withstand the rigorous conditions of heavy fabrication environments. The holder is rated for a 60% duty cycle at 400 Amps, making it suitable for structural steel, pipe welding, and heavy equipment repair. It accommodates a wide range of electrode diameters, typically from 1/16 inch (1.6mm) up to 1/4 inch (6.4mm), providing versatility across various welding procedures.

One of the key technical features of the Bernard 40B is its modularity. The head of the holder is replaceable, allowing maintenance teams to swap out the wear component without discarding the entire unit. This feature significantly lowers the long-term total cost of ownership. The handle is ergonomically designed to provide adequate grip while maximizing distance from the heat source, and the cable connection point is designed for secure termination of 2/0 to 4/0 welding cables.
