14N ceramic nozzle wear-resistant alumina ceramic
Product Overview
Alumina nozzle
The argon arc welding nozzle is an accessory at the front end of
the welding gun, which plays a protective role. Commonly known as:
porcelain nozzle, argon welding nozzle
The various types of porcelain nozzles produced by the company are
strictly monitored from the preparation of raw materials,
processing, firing, and inspection of finished products to ensure
that customers are provided with high-quality and cheap products.

Product advantages
Argon arc welding alumina welding ceramic nozzle series has the
characteristics of high temperature resistance, strong reliability
and price concessions.
1. The structure is simple. It is suitable for mass production and
can improve work efficiency by dozens of times.
2. Good insulation. Due to the insulation and non-conductivity of
the ceramic nozzle, during the welding process, unlike the copper
nozzle, once the metal splash gradually accumulated on the inner
wall is connected to the welding wire, the nozzle touches the
workpiece, and a short circuit will occur, causing sparks and
burning out .
Applications
1. Textile machinery
2. Lighting
3. Petrochemical
4. Automotive industry
5. Medical machinery
Product packaging
Packed in carton
