Unverified大风量利于快速加热大面积，但精密维修时风量过大会吹飞0402/0201贴片元件，需可调至最低风量或换窄喷嘴，风量与操作精细度相互矛盾85% similarUnverified风速档位越高热效率越高，但高风速会加剧散热带走热量、拆焊时反而更难达到熔锡温度；焊接细密元件应低风速+适中温度组合72% similarUnverified双热管+涡轮风扇（热风循环）机型比单一底部加热的均匀度显著更好，减少中途翻面次数；选购时确认标注'360°热风循环'72% similarUnverified容量越大均匀度越难保证，大容量机型必须搭配360°立体热风或双风扇设计才能弥补，否则会出现边缘焦糊中心夹生71% similarUnverified迷你主机长时间高负载后表面温度和进出风口温度较高，需确保放置环境通风，避免嵌入密闭柜体或紧贴墙面，否则易触发降频甚至死机70% similar
