电烙铁是无线电爱好者或电器维修人员经常使用的电热工具,使用过程中如何充分利用有效热量,提高使用功辜,述到下甩乙目的,是一个值得注意的间题。在使用烙铁的过程中,往往由于长期使用,烙铁铜头外露部分被氧化而变细变短,这就降低了它的导热性能和热容量,从而逐渐降低其使用性能。针对这种情况进行 Electric soldering iron is often used by radio enthusiasts or electrical service personnel. It is a noteworthy issue how to make full use of effective heat during operation to improve the use of electricity. In the process of using a soldering iron, since the exposed part of the iron copper head is oxidized and becomes thinner and shorter due to long-term use, its thermal conductivity and heat capacity are reduced, thereby gradually lowering its serviceability. For this situation
