采用国际标准和国外先进标准是我国的一项重要技术经济政策。通用的基础标准、试验方法标准以及安全、卫生、环境保护等标准,应该与国际标准协调一致。对于产品性能、指标等,一般说来应该积极采用,但也未必条条照搬,必须根据我国国情,区别对待。手工电弧焊机有静止式和旋转式之分。静止式焊机虽然种类繁多,但都必须有焊接变压器。国际标准ISO700—1982(用于焊条手工电弧焊和TIG焊电源)规定:在自然或强制风冷的情况下,静止式焊机温升限值采用IEC76—1976(电力变压器)的数值,如表1。绝缘材料等级的划分和相应温度值按IEC85
The adoption of international standards and advanced foreign standards is an important technical and economic policy in our country. Common basic standards, test methods and standards of safety, health, environmental protection and other standards, should be consistent with international standards. For product performance, indicators, etc., generally should be actively adopted, but not necessarily Article copy must be based on China’s national conditions, the difference treated. Manual arc welder has static and rotary points. Although a wide range of static welding machine, but must have a welding transformer. International Standard ISO700-1982 (for electrode arc welding and TIG welding power source) provides: In the case of natural or forced air cooling, static welding temperature limit using IEC76-1976 (power transformer) values, such as the table 1. Insulation material classification and the corresponding temperature value according to IEC85
