15AK conductive nozzle

The 15AK conductive nozzle is the core consumable of the European MIG/MAG gas shielded welding gun, designed specifically for the 15AK series welding gun. With its meticulous adaptability and stable performance, it has become a commonly used accessory in small and medium-sized welding scenarios. The detailed introduction is as follows:

Definition and core role

The 15AK conductive nozzle is a key component at the tail end of the welding gun responsible for guiding the welding wire and conducting the current. Its core function is to stably transmit the welding current to the welding wire, guide the welding wire to be sent out at a constant speed and in detail, confirm the continuous and stable combustion of the arc, reduce current fluctuations and wire feeding jamming during the welding process, and be the core consumable for protecting the quality of weld formation and improving welding efficiency.

Material selection and process characteristics

Mainstream materials:

Copper (E-Cu): With excellent conductivity and thermal conductivity, low current transmission loss, suitable for argon mixed gas MIG welding scenarios, good cost performance, it is an honest merchant material for conventional welding.

CuCrZr: On the basis of maintaining good conductivity, its hardness and performance are significantly improved. It has high temperature resistance (based on actual reports), strong corrosion resistance, and a longer service life than ordinary copper materials. It is suitable for CO ₂ gas MAG welding or high-frequency welding scenarios. Although the cost is slightly higher, the overall cost of use is better.

Processing technology: High speed drilling and extrusion molding processes are adopted, and some products are processed by precision machining. The inner hole surface has high smoothness, no burrs, no defects, and excellent results, reducing the frictional resistance during wire feeding and protecting the 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 15AK 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 ensure that the direction of the welding wire is precise and avoid deviation.

Core specifications:

Length: Typically 25mm, 51mm and other specifications, suitable for installation requirements of different 15AK welding gun models.

Inner hole diameter: covering various sizes such as 0.6mm, 0.8mm, 0.9mm, 1.0mm, 1.2mm, etc., carefully matching the corresponding diameter of the welding wire. The gap control between the hole diameter and the welding wire diameter is reasonable, taking into account the smoothness of wire feeding and the stability of conductivity.

Packaging: Common specifications include 10 pieces/pack, 20 pieces/pack, 16PCS set, etc. Some cross-border supply products use large packaging of 200 sets/box to meet personal operation and industrial batch use needs.

Performance Highlights

Conductive stability: The combination of excellent copper material and meticulous processing technology ensures uniform current transmission, smooth arc combustion, reduces welding defects such as porosity and undercutting, and makes the weld formation smoother and more uniform.

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.

Strong adaptability: specially designed for the European 15AK series MIG/MAG welding gun, compatible with all MB15AK welding gun models, with strong replaceability, can directly replace original accessories, high fit after installation, and no risk of gas leakage.

Good practicality: The chromium zirconium copper material version is resistant to high temperatures (based on actual reports) and wear, while the purple copper material version has good thermal conductivity, which can avoid deformation and damage at high temperatures, extend service life, reduce accessory replacement frequency and usage costs.

Application scenarios

Suitable for small and medium-sized welding operations, widely used in mechanical manufacturing, automotive maintenance, furniture processing, interior decoration, electrical equipment assembly and other scenarios, compatible with CO ₂ gas shielded welding, argon mixed gas shielded welding and other processes. Whether it is thin plate welding or conventional welding of medium and thick plates, it can exert stable performance and is a commonly used accessory for skilled workers and welding enthusiasts.
