Product Introduction
This welding-specialized mixed gas is precision formulated with 99.999% ultra-high purity argon and 99.9% industrial grade carbon dioxide, following the classic 82:18 volume ratio that is widely recognized as the optimal blend for mainstream metal active gas (MAG) welding. It perfectly integrates the superior inert shielding performance of high-purity argon with the arc-stabilizing and weld pool-fluidizing characteristics of carbon dioxide, making it a reliable choice for high-quality metal welding processing.
As the core shielding gas for MAG welding, this blend excels in welding carbon steel, low-alloy steel and structural steel components, which are extensively used in automotive manufacturing, construction machinery production, pipeline fabrication and sheet metal processing. The 82% high-purity argon forms a dense and stable shielding layer around the weld zone, effectively preventing oxidation and nitridation of the weld metal and avoiding common welding defects such as porosity and undercutting. The 18% carbon dioxide optimizes arc ignition performance and heat distribution, significantly reducing welding spatter, improving weld pool fluidity, and ensuring smooth, uniform weld seams with high tensile strength and excellent mechanical properties.
We adopt professional precision gas mixing equipment and strict full-process quality control, ensuring the concentration tolerance of each component is within ±0.5%vol and the gas composition is highly uniform throughout the cylinder. All raw material gases meet the specified purity standards, and each batch of mixed gas undergoes rigorous purity and uniformity detection, with complete traceability records of raw material sources and mixing processes. We provide standard high-pressure gas cylinders with reliable sealing performance, and offer targeted on-site technical guidance for different welding processes, ensuring a safe, stable and efficient gas supply for various metal welding production scenarios.

FAQ
Q: Can gas cylinders be exposed to sunlight or close to heat sources?
A: Exposure to sunlight or close to heat sources is strictly prohibited. High temperature will cause the gas pressure in the cylinder to rise sharply, exceeding the pressure resistance limit of the cylinder and causing cylinder explosion.
Q: Which gases cannot be stored together?
A: Gases that are prone to chemical reactions such as hydrogen and oxygen, acetylene and chlorine, ammonia and hydrogen chloride are strictly prohibited from being stored together to prevent explosion or poisoning accidents.
Q: What should be checked before using gas cylinders?
A: Check whether the cylinder valve is intact and leak-free, whether the cylinder body has cracks and deformation, whether the pressure gauge and pressure reducing valve work normally, and confirm that the gas type is consistent with the label.
