Introduction to the differences between 30w and 60w soldering irons
The electric soldering iron is an essential tool for electronic production and electrical appliance repair. It is mainly used for welding components and wires. According to the mechanical structure, it can be divided into internal heating type electric soldering iron and external heating type electric soldering iron. According to the function, it can be divided into non-soldering soldering iron and soldering iron. Tin-type soldering irons are divided into high-power soldering irons and low-power soldering irons according to different uses.
How to use a soldering iron
① The electric soldering iron must be tinned before use. The specific method is: heat the electric soldering iron. When the solder has just melted, apply solder paste, and then apply the solder evenly on the soldering iron tip so that the soldering iron tip can be evenly coated. layer of tin.
②How to tin the wire head: Tighten the wire head into a twist shape and apply solder paste. Dip an appropriate amount of solder into the tip of the soldering iron, touch the head of the wire and rotate the wire. After the solder is completely melted and immersed in the head of the wire, gently lift the head of the wire up and away from the tip of the soldering iron.
③Welding method of wires and fork-type terminals: First, tin the head of the wire, then insert it into the tail conduit of the fork-type terminal, dip an appropriate amount of solder with the tip of the soldering iron, and touch the solder joint until all the solder on the solder joint is After melting, gently lift the soldering iron tip up along the terminal and away from the solder joint. The solder joint should be in the shape of a sinusoidal wave peak, the surface should be bright and smooth, without tin thorns, and the amount of tin should be moderate.
The difference between 30w and 60w soldering irons
30W and 60W soldering irons have different powers, different temperatures they can reach, and different heating speeds. For devices with relatively small thermal capacity and sensitive to temperature, it is best to use a low-power soldering iron. 60W can replace 30W, but 30W cannot replace 60W.
The relationship between power and temperature:
15W280℃----400℃
20W290℃----410℃
25W300℃----420℃
30W310℃----430℃
40W320℃----440℃
50W320℃----440℃
60W340℃----450℃
