随着焊接工艺要求的提高,可调温度的电烙铁具有重要作用。提供一种新型可调温度电烙铁的设计,其电路主要由电容降压整流电路、自动控制电路和加热指示电路构成。该设计不仅能通过结构简单的反馈回路自动调节固定温度,而且用户还可根据需要调节电位器使其处于多个不同的温度范围,并具有较高精确度,完全满足不同应用需求。
- Abstract:
- With the welding process required to raise,the adjustable temperature of the electric iron is to play an important role.A new type of electric iron with adjustable temperature is provided.The circuit is composed of capacitor step-down reatifier,automatic control and heating circuit constitute instructions.The design not only automatically adjusts fixed temperature through a simple feedback loop,but also adjusts potentiometer to make them in a number of different temperature ranges.The system design is high accuracy,meet the needs of different users.
