0160362025 - ESAB OKC 50 Male Welding Cable Connector 35-50mm²

Technical Overview of the ESAB OKC 50 Male Connector

The ESAB OKC 50 Male Cable Connector (SKU: 0160362025) is a premium-grade electrical component designed for the rigorous demands of industrial welding applications. Engineered to facilitate the safe and efficient transmission of high-amperage welding current, this connector is an essential part of the secondary circuit in manual metal arc (MMA), TIG, and MIG/MAG welding setups. The OKC series is renowned for its reliability, utilizing a bayonet-style locking mechanism that ensures a low-resistance connection between the power source and the welding cable, or between cable extensions.

This specific model is sized for welding cables with a cross-sectional area ranging from 35mm² to 50mm². The connector body is manufactured from high-conductivity brass, machined to precise tolerances to ensure optimal surface contact within the mating socket. This precision reduces voltage drop across the connection, thereby maintaining arc stability and minimizing heat generation at the joint. The metallic components are encased in a durable, oil-resistant rubber sleeve that provides electrical insulation and mechanical protection against impact, abrasion, and environmental contaminants such as grease and moisture.

Installation of the OKC 50 is straightforward, utilizing a mechanical crimp or screw-down method (depending on the specific revision and preference) reinforced by a copper sleeve that protects the fine copper strands of the welding cable from damage during tightening. The connector complies with international safety standards for welding equipment, ensuring compatibility with a wide range of power sources that utilize standard OKC or Dinse-style receptacles. For maintenance and repair operations (MRO), the ESAB OKC 50 represents a standard of quality that ensures equipment uptime and operator safety.

In professional environments where equipment mobility is key, the quick-disconnect feature allows welders to rapidly change leads or extend cables without the use of tools. The locking action is positive and tactile, preventing accidental disconnection during cable dragging or repositioning. By maintaining a secure electrical path, the ESAB OKC 50 helps preserve the duty cycle of the welding machine and protects the cable ends from fraying and oxidation.
