0700006900 - ESAB 200A Stick Welding Lead Assembly 3m OKC50

Technical Overview of the ESAB MMA Welding Cable Assembly

The ESAB MMA Welding Cable Assembly (SKU: 0700006900) is a pre-assembled secondary circuit conductor designed for Manual Metal Arc (MMA) welding applications. This assembly is engineered to facilitate the transfer of high-current electrical energy from the welding power source to the electrode holder with minimal voltage drop and thermal loss. The unit features a 3-meter length of high-conductivity copper cabling, rated for a maximum current of 200 Amperes. This amperage rating makes it suitable for a wide range of general fabrication, maintenance, and repair operations where standard electrode diameters are utilized.

At the machine connection end, the cable is terminated with an OKC 50 connector. The OKC 50 is a bayonet-style coupling, often referred to as a Dinse connector, which provides a secure, low-resistance electrical junction that can be quickly connected or disconnected with a quarter-turn motion. This standard is widely adopted across European and international welding equipment, ensuring compatibility with a broad spectrum of ESAB power sources as well as compatible machines from other manufacturers. The connector is designed to prevent accidental decoupling during operation while maintaining optimal conductivity to prevent localized heating at the terminal.

The electrode holder attached to the working end is designed for ergonomic handling and secure electrode retention. It utilizes a robust clamping mechanism to hold stick electrodes firmly in various positions, accommodating different welding angles required in complex joint configurations. The cable insulation is formulated from durable, heat-resistant rubber compounds that offer protection against sparks, spatter, oil, and mechanical abrasion common in industrial environments. The flexibility of the cable assembly is a critical technical feature, reducing the mechanical load on the welder's wrist and allowing for precise manipulation of the electrode holder during the welding process.

This assembly meets ESAB's stringent quality standards for electrical safety and durability. It is an essential component for maintaining the integrity of the welding circuit, ensuring that the preset parameters at the power source are accurately delivered to the arc. Regular inspection of welding cables for insulation damage or connector wear is recommended to maintain safety and weld quality.
