What's the difference between an electric soldering iron and a 30w40w60w?
The greater the power, the faster the fever. But if used to solder tight solder joints, such as IC, the bigger the better, unless it's temperature controlled.
Power problems, high power, high temperature, melting effect is better, but also relatively costly... Not used 30W is enough, and then bought to protect rosin.
High power, high temperature, but large power consumption.In general, if used in welding integrated circuits, 30W is enough. If it needs soldering tin, it is better to use 60W.
The difference between the size of the power is to weld things, welding pieces of relatively small, not high temperature, with little power, such as miniature circuit, general 30W can, some larger metal parts heat will soon need more power. Power is too small, heat fast, welding is not secure.
