50-70 plug socket

This is a set of DKJ50-70 series welding plug sockets, which are key components for connecting high current welding equipment (such as heavy-duty welding machines and large welding guns) with cables, used for stable transmission of welding current. The detailed introduction is as follows:

Material and Structure

Conductive components: Made of high-purity copper material with excellent conductivity and thermal conductivity, capable of withstanding a large welding current of 400A, confirmed to have low current transmission loss and stable welding arc.

Insulated casing: The casing of plugs and sockets is made of high-temperature resistant (based on actual reports) insulated rubber (black body), which has good insulation and wear resistance, and can maintain structural stability in high-temperature welding environments, avoiding the risk of leakage.

Connection design: The plug is a pin type structure, and the socket is a socket type structure, which achieves conductivity through tight contact of metal contacts. Some models have threaded or locking designs to ensure a secure connection and prevent poor contact caused by vibration during welding.

performance advantage

Stable high current carrying capacity: The purple copper material protects the uniform transmission of high current, avoiding heat loss caused by excessive contact resistance and protecting welding quality. It is suitable for high current transmission of heavy-duty welding machines, large gas shielded welding machines and other equipment.

Good insulation performance: The rubber shell has excellent insulation performance, which can effectively prevent the risk of electric shock. At the same time, it has a certain ability to resist drops and aging, and has a long service life.

Easy to operate: The plug and socket design is simple, and the connection between cables and welding equipment can be achieved at a suitable speed, improving the efficiency of welding operations.

Specifications and Applications

Specification and model: DKJ50-70 series, rated current 400A, suitable for cable diameters typically ranging from 50-70mm ².

Application scenarios: Widely used in heavy-duty manual welding, large-scale gas shielded welding, heavy industry welding and other scenarios, it is a universal accessory for connecting high current welding equipment and cables, confirming the stable transmission of welding current.

Precautions

Regularly check the contact parts of the plug and socket, remove the oxide layer and dirt, and confirm good conductivity.

When plugging or unplugging, it is necessary to confirm that the device is powered off to avoid electric arc burns caused by live operation.

Select the corresponding type of plug and socket according to the welding current and cable specifications to avoid overload use.
