快速升温烙铁升温快,5秒左右即可达到熔锡温度,不需长时间通电加热等待;不焊接时没有温升,即使忘记断开插头与电源的连接,也不至于发生事故。但一般快速升温烙铁头均采用裸铜丝制作,这势必导致下述问题: 1.铜丝易变形受变压器体积、重量等因素制约,通常烙铁头采用φ2mm以下铜丝制作,由于铜丝较细,机械强度有限,加之通电加热后强度又有所下降,工作时稍用力,铜丝就易变形,影响了使用效果。 2.铜丝易氧化烙铁头常烧死不沾锡,给使用带来麻烦。 3.热能损失大铜丝各部电阻相同,通电后,整根铜丝均匀
Rapid warming Iron heat up quickly, about 5 seconds to reach the melting tin temperature, without prolonged power heating wait; no welding without temperature, even if you forget to disconnect the plug and the power connection, it will not be an accident. However, the general rapid heating tip are made of bare copper wire, which will inevitably lead to the following questions: 1. Copper deformation easily affected by the transformer size, weight and other factors, usually iron head with φ2mm following copper wire production, the smaller copper wire , Mechanical strength is limited, coupled with the power intensity after heating has declined, working a little harder, easy deformation of copper wire, affecting the use of results. 2. Copper easy to oxidize the iron head often burn non-stick tin, to bring trouble to use. 3. Loss of heat Large copper wire parts of the same resistance, power, the entire root of copper wire uniform
