What's the difference between an electric iron and an outside heat? Which one is better?
The outer heat type is better, it is better to buy a temperature adjustable, 60 watt, with grounding wire.I have been using this, Nanjing meihua,But now I don't use the soldering iron and switch to the soldering pad
The high efficiency of heating, fast heating, easy to use, but the heating core and the tip are easily broken, but these are very cheap, and convenient replacement, often because of external heat type fastening screw corrosion and difficult to replace, so I love with heat type. A 20W has an internal heat equal to 25 30W heat. Longevity type external hot electric iron, not to buy, it is difficult to tin!
The inner heating type is that the shell of the iron is heat transferred to the head, and the heat utilization efficiency is higher than the outer heat type, while the outer heat type is opposite, and the heating core is easy to break. Brand does not matter, when buying more expensive quality is much better. Cheap is easy.
