24KD conductive nozzle

The 24KD conductive nozzle is a one-to-one core consumable for the European MIG/MAG gas shielded welding gun, designed specifically for the 24KD series welding gun. It has a rated welding current of 240A and is suitable for medium and low load welding scenarios due to its high strength structure and stability performance. It is a commonly used accessory for industrial welding and specialized operations. The detailed introduction is as follows:

Definition and core role

The 24KD conductive nozzle is a key component at the end of the welding gun responsible for conducting current and feeding welding wire. Its core function is to stably transmit welding current to the welding wire, while carefully guiding the welding wire to be sent out at a constant speed, confirming the continuous and stable combustion of the arc, and cooperating with protective gas to isolate air, prevent weld oxidation, reduce welding defects such as porosity and arc deviation. It is the core consumable for protecting welding quality and operational efficiency.

Material selection and process characteristics

Mainstream materials:

Copper (E-Cu): It has excellent conductivity and thermal conductivity, low current transmission loss, high temperature resistance (based on actual reports), good corrosion resistance, and practical texture. It is an economical choice for conventional welding scenarios and is suitable for most CO ₂ gas shielded welding and argon mixed gas welding processes.

CuCrZr: On the basis of maintaining good conductivity, its hardness and performance are significantly improved. It has strong high temperature resistance (based on actual reports) and a longer service life than ordinary copper materials. It is suitable for high-frequency and long-term welding operations, especially for aluminum wire welding and other scenarios that require high wear resistance (based on actual reports).

Coated version: Some products are treated with surface coating, which has anti splash function, reduces the adhesion of splashes during welding, lowers the cleaning frequency, and extends the service life.

Processing technology: Suitable precision drilling and extrusion molding processes are adopted. Some excellent products are processed by precision machining, with high surface smoothness of the inner hole, no burrs or defects, fine aperture size, and reasonable clearance with the welding wire (usually 0.1-0.2mm larger than the diameter of the welding wire). The effect is excellent in reducing the friction resistance of wire feeding, protecting the stability of conductivity and smoothness of wire feeding.

Structural design and specification parameters

Appearance structure: The overall shape is cylindrical, with a standard M6 threaded interface at one end, which can be securely connected to the 24KD welding gun conductive seat at a suitable speed. It is easy to install and disassemble without the need for complex tools; The other end is the outlet end of the welding wire, which has been finely polished to confirm that the direction of the welding wire is fine, avoiding deviation, and protecting the compatibility with the protective nozzle to prevent gas leakage.

Core specifications:

Length: Conventional specifications include 25mm, 28mm, 30mm, 40mm, 45mm, etc., suitable for the installation requirements of different 24KD series welding guns. Some models have a wall thickness of up to 5.5mm-8.8mm and high structural strength.

Inner hole diameter: covering various sizes such as 0.6mm, 0.8mm, 0.9mm, 1.0mm, 1.2mm, 1.4mm, 1.6mm, etc., carefully matching the corresponding diameter welding wire. Among them, 0.8mm, 0.9mm, 1.0mm, 1.2mm are commonly used specifications, and the inner hole size of the aluminum wire will be appropriately increased to meet the welding needs of aluminum wire.

Compatible Welding Gun: Designed specifically for SN-24, 24, 25 series MIG welding guns and SM200N wire feeding guns, it can also adapt to SN-36 and 36 series MIG welding guns with M6 conductive nozzle holders, compatible with European standard welding guns such as Binzel MB24KD.

Packaging: Commonly 10 pieces/pack, 20 pieces/pack, industrial batch packaging includes specifications such as 69 pieces/set, 200 pieces/box, etc., to meet individual operations and large-scale production needs.

Performance Highlights

Stable conductivity: The combination of excellent copper material and meticulous processing technology ensures uniform current transmission, smooth arc combustion, and excellent results in reducing welding defects, making the weld seam smoother and more uniform, and improving the welding qualification rate.

Smooth wire feeding: The inner hole has high smoothness, low friction resistance, and there is no jamming or dragging when the welding wire passes through. It is suitable for manual welding and small automated welding equipment, reducing operational difficulty and improving work efficiency.

Strong adaptability: Strictly following the European welding gun standard, it can directly replace original accessories, has strong compatibility with 24KD series welding guns and related consumables (protective nozzle, conductive seat), good replaceability, and does not require adjusting the welding gun structure.

Good practicality: The thickened wall thickness design combined with excellent copper material has outstanding resistance to deformation and wear, and is not easily damaged in high temperature environments. The purple copper material has a good cost performance ratio, while the chromium zirconium copper material has a longer service life, reducing replacement frequency and usage costs.

Application scenarios

Suitable for the European 24KD series MIG/MAG gas shielded welding gun, it is widely used in mechanical manufacturing, automotive maintenance, steel structure welding, furniture processing, electrical equipment assembly, thin plate welding and other scenarios. It is compatible with CO ₂ gas shielded welding, argon mixed gas shielded welding and other processes, and can meet the needs of manual welding operations as well as small automated welding production lines. It is a versatile and specialized welding consumable.
