How to weld with several tips?
Embodying a good job with lead solder bar is not that difficult, but there are details that need to be considered to ensure quality and achieve as close as possible to the excellent weld drag. For this we prepared this text on how to weld with several tips that, combined with a little execution, will make you an excellent maker of electronic sketches.
What is welding done?
Traditionally, welding is composed primarily of tin (Sn) and lead (Pb) and similarly with a little more metals to provide the desired qualities. However, it was discovered that lead is a metal contrary to humans and can even cause botulism.
With that, some countries decided to ban the use of lead in the welding compound. In this way, lead solder bar or lead-free welding emerged. And it became the standard in the construction of electronic equipment.
You already know what tools you will need.
This is the essential equipment for a great welding and it really pays to attack and acquire a great quality. Soldering irons are not quite expensive. And a good soldering iron has a beautiful correlation with the advantage of making your work with a better quality and similarly ensuring the safety of your surgery.
You prefer quantity for a welding season with changeable temperature. The welding stations ensure that your welding iron works at the correct temperature and that it stays constant. It makes work easier and a better final result.
The welding sucker is a piece of equipment that does not need to evade in your bank. It has been described to dispense welding as much as possible and let you do quality work. To use it, simply arm the suction by pressing the piston all the way down.
You should place the silicone tip over the weld that you want to. And, therefore, press the key that releases the piston and sucks lead solder bar.
And don't forget to read our text on how to set up your electronics bank with several other tips on equipment and tools.
The value of cleaning the soldering iron tip
Preserving the tip of the constantly open soldering iron will guarantee better thermal conduction and, consequently, better welds. You need to sharpen the tip of your soldering iron constantly. It is to verify that it is getting dark because of the concentration of waste and rust. For this you can use steel sponges or others that are specific for the cleaning of welding irons.
After checking the tip of the lead solder bar in the steel drinker, you can pass it over a moistened drinker (of these kitchen or specific for this case) to assist in cleaning.
Some suggestions to use lead solder bar
It is not advisable to use materials that generate a lot of conflict. The withdrawal of money from the tip of the soldering iron will significantly decrease its beneficial life.
In short, welding!
With all the preliminary tips in mind, it's time to get everything running:
Preliminary tips for soldering
Start with an excellent cleaning of the region where the welding will be applied.
Allow the soldering iron to heat up and reach the essential temperature to melt the solder.
Some welding stations contain an LED that indicates when this resulted or even a display that shows the temperature of the welding iron. However, you can analyze if the temperature is correct by trying to sensitize a little bit of lead solder bar on the tip of the iron.
Put a little solder on the tip of the soldering iron. This will assist in welding processing. Avoid leaving it too loose on the tip of the iron, as it can make a drip and it falls into its spin causing shorts and disrupting your work.
Methods to follow while soldering
Now just rest the soldering iron in the region that will receive the welding and let it pass heat to heat the place. Subsequently apply the welding over the region and it will then melt even. Apply the weld and let it advance until you verify that you have placed a satisfactory weld and therefore stop.
Wait a few seconds for the weld to solidify and compromise the components.
Stay tuned so as not to over-weld and cause short circuits. If you find that you have over-welded, remove the lead solder bar with a sucker and do it again.
How solder is used in electronics components
Take care as some components can be damaged if they become very hot during the welding process. To prevent this from happening try to perform the welding quickly so that the element does not receive enough heat from the soldering iron.
A soldering iron is normally used to solder electronic components on printed circuit boards. It has an electric heating element that heats the tip to a high temperature. Generally, the iron is heated to a temperature of around 370ºC, but it can reach more than 420ºC for lead-free solders.
Due to its high energy consumption and the heat produced, there are dangers associated with leaving a lead solder bar on.
Heat can cause a fire
Many modern soldering irons now come with an automatic shutdown feature, which shuts off your heating element after a specified period of time. Irons that do not have this feature will continue to heat the element so that the tip temperature remains warm.
If the tip of the iron is in contact with something else, it may be burnt or damaged due to the constant supply of thermal energy from the heating element of the soldering iron. In the worst case, this heat can cause a fire if flammable material is nearby.
Soldering iron short circuit can cause a fire
A lead solder bar iron that is kept on will continue to draw current from the electrical outlet. If the heat is rapidly dissipating, for example, when the iron is kept in a cold room, the current will be continuous. This current can heat the cables, melt their insulation and create short circuits.
A short circuit in the AC line can be quite dangerous as it can cause a fire.
A soldering iron kept on in a cold environment for an extended period of time continues to draw electrical current from the power supply in order to keep its tip at the specified temperature.
This constant extraction of current can cause your heating element to burn and create conditions for an intermittent electrical short circuit. That is, the short occurs whenever the wire of the heating element touches the metal tube it is inside. In this case, the person handling the lead solder bar may suffer an electric shock, which can be life threatening.
