-✅ In a hot-air handle with only heater + temperature sensor, no fan and no reed switch

-

-The internal parts are:

-

-Heating element (ceramic heater) → always 2 wires

-

-Temperature sensor → usually 2 wires

-

-Protective ground wire → 1 wire

-

-This adds up to 5 wires, matching your description.

-Yes, the tip of a soldering iron usually has a surface coating, not just bare copper or iron. This coating serves several purposes: preventing corrosion, improving heat transfer, and extending lifespan. Common types of coatings include:

-

-1. **Iron Plating**

- - Most soldering iron tips have a copper core, but copper oxidizes easily and wears quickly.

- - The surface is plated with iron to prevent oxidation and improve durability.

- - Advantages: High temperature resistance and long lifespan.

-

-2. **Nickel or Chrome Plating**

- - Some tips add a layer of nickel or chrome on top of the iron plating.

- - Purpose: Further corrosion resistance and increased surface hardness.

-

-3. **Solder Coating (Tin layer, formed during use)**

- - When first used, a thin layer of solder forms on the tip from molten solder or flux.

- - This tin layer protects the tip from oxidation and improves soldering performance.

- - Tip: Always apply a thin layer of solder after use to extend the tip’s life.

-

-4. **Ceramic or Special Coatings (on some high-end tips)**

- - Some high-temperature or specialty soldering tips have ceramic coatings.

- - Purpose: Corrosion resistance, high temperature tolerance, and reduced solder sticking.

-

-**Summary**: The core is usually copper, with an iron plating, sometimes additional nickel/chrome, and a protective tin layer forms during use.

-## cap super spot soldering

-

-Capacitor Discharge Spot Welder (简称 CD Spot Welder)

-

-电容不是电池，电容可零伏电压存放，长期使用免维护，没有记忆效应，也不存在过度放电的问题，比如吃灰2两年拿出来都可正常使用！

-大电流放电能力超强

-可长期使用实用工具，绝不是短期玩具！
