1. EQUIVALENT STANDARD AND CONFORMITY
2. CHARACTERISTICS AND APPLICATION
- The basic advantage of automatic and semi-automatic welding under the flux layer of EL12 trực tiếp bóng đá keo nha cai is to ensure the quality of the weld, which has uniformity, high productivity, and the ability to save trực tiếp bóng đá keo nha cai.
- The EL12 allows the use of high trực tiếp bóng đá keo nha cai amperage, high heat source usefulness, and fully automated or fully automated operations that cause – maintain the arc – move the wire to the full length of the weld.
- EL12 is a trực tiếp bóng đá keo nha cai with low carbon content, medium manganese and silicon content, and extremely small sulfur and phospho- rus impurities, creating welds with high strength and toughness.
- EL12 is built with high precision, even wire direction, and is plated with a layer of high purity copper for preservation and stable solder- ing.
