Cordless iron
Small irons heated by a battery, or by combustion of a gas such as butane in a small self-contained tank, can be used when electricity is unavailable or cordless operation is required. The operating temperature of these irons is not regulated directly; gas irons may change power by adjusting gas flow. Gas-powered irons may have interchangeable tips including different size soldering tips, hot knife for cutting plastics, miniature blow-torch with a hot flame, and small hot air blower for such applications as shrinking heat shrink tubing.

Simple Electric Soldering Iron
For electrical and electronics work, a low-power iron, a power rating between 15 and 35 watts, is used. Higher ratings are available, but do not run at higher temperature; instead there is more heat available for making soldered connections to things with large thermal capacity, for example, a metal chassis.[10] Some irons are temperature-controlled, running at a fixed temperature in the same way as a soldering station, with higher power available for joints with large heat capacity. Simple irons run at an uncontrolled temperature determined by thermal equilibrium; when heating something large their temperature drops.

A variation is the Scope soldering iron, common in Australia, which operates from a low-voltage source such as transformer or battery, and heats in seconds when the user pushes the thumb-guard, which then acts as a heat controller.

What is soldering iron?

A soldering iron is a hand tool used in soldering. It supplies heat to melt solder so that it can flow into the joint between two workpieces.

A soldering iron is composed of a heated metal tip (the bit) and an insulated handle. Heating is often achieved electrically, by passing an electric current (supplied through an electrical cord or battery cables) through a resistive heating element. Cordless irons can be heated by combustion of gas stored in a small tank, often using a catalytic heater rather than a flame. Simple irons, less commonly used today than in the past, were simply a large copper bit on a handle, heated in a flame.

Solder melts at approximately 185 °C (365 °F). Soldering irons are designed to reach a temperature range of 200 to 480 °C (392 to 896 °F).

Soldering irons are most often used for installation, repairs, and limited production work in electronics assembly. High-volume production lines use other soldering methods.[1] Large irons may be used for soldering joints in sheet metal objects. Less common uses include pyrography (burning designs into wood) and plastic welding (as an alternative to ultrasonic welding).

How to select the sodering iron tip?

1. Pointed soldering tip: the tip is very thin, suitable for fine welding, or the situation where the welding space is small, and can also correct the excess tin produced when welding chips.

2. Round tip soldering tip: The whole front end of the soldering iron tip can be soldered, suitable for general soldering, regardless of the size of the solder joint.

3. Slotted solder tip: Use both sides of the soldering iron tip for soldering, suitable for soldering that requires a lot of tin, such as a soldering environment with large soldering area, thick terminals, and large soldering pads.

4. Cutter head (K shape) welding tip: use the blade face for welding, suitable for drag welding: the marked cutter head is also divided into small cutter heads!

5. Horseshoe-shaped welding nozzle: suitable for large welding area, thick terminals and large solder joints.

Reasons and solutions for soldering iron tip not sticking tin

The usual way to deal with it is to use a knife to scrape off the oxide layer of the soldering iron head to expose the copper that has not been oxidized by the air. Then, put it in the rosin box and dip it, then dip it in tin, and it can be used normally. However, this method does not remove it thoroughly. At the same time, if it is scraped off for a long time, the tip of the soldering iron will become thinner and affect heat transfer, resulting in a drop in temperature and even damage to the tip of the soldering iron.

The quick and efficient treatment method is: hold the wooden handle of the electric soldering iron, immerse the oxidized soldering iron tip in a container filled with alcohol, take it out after 1 to 2 minutes, the oxide will be completely and cleanly removed, and the soldering iron tip will look brand new. This is because after the copper oxide and alcohol are heated, a chemical reaction occurs, and the copper is reduced, which has no corrosion effect on the tip of the electric soldering iron.

Precautions for using electric soldering iron

2 Before soldering, the excess part of the lead wire of the component should be cut off and tinned. If the surface of the component is oxidized and not easy to tin, you can use fine sandpaper or a knife to clean the surface of the lead, and use a soldering iron tip to dip an appropriate amount of rosin core solder to tin the lead.

If you still can't hang tin, you can put the component lead on the rosin block, then touch the lead lightly with the tip of the soldering iron, and turn the lead at the same time, so that the surface of the lead can be evenly tinned.

The tinning time of each lead should not be too long, generally 2~3 seconds is appropriate, so as not to burn the inside of the component, especially when tinning the pins of diodes and triodes, it is best to use metal tweezers to hold the lead against the shell part, so as to transfer part of the heat away. in addition,

3. After welding, carefully observe the shape and appearance of the solder joints. The solder joints should be hemispherical and the height is slightly smaller than the radius. They should not be too bulging or too flat. The appearance should be smooth and uniform without obvious pores or depressions, otherwise it will easily cause false welding or false welding. When welding the leads of several components at the same time, more attention should be paid to the quality of the solder joints.

Precautions for using electric soldering iron

The pins of various components should not be cut too short, otherwise it is not conducive to heat dissipation and soldering.

1. When soldering, place the lead wire of the component with tin on the position to be soldered, such as in the pad hole of the printed board or in the small hole of the solder piece of various joints, sockets and switches, and use a soldering iron tip with an appropriate amount of tin to solder The part stays for about 3 seconds, and after the soldering iron is removed, a smooth solder joint is formed at the soldering place.

In order to ensure the quality of welding, it is best to hang tin in advance at the position of the lead wire of the welding component. When welding, make sure that the position of the lead wire does not change, otherwise it is very easy to cause false welding. The soldering iron tip should not stay for too long, otherwise it will burn the components, and if it is too short, it will cause false welding due to insufficient welding melting.

Basic steps of welding operation

Step 1: Prepare for welding. Hold the welding wire in your left hand and the soldering iron in your right hand, and enter the welding preparation state. The tip of the soldering iron is required to be kept clean, free of oxides such as welding slag, and coated with a layer of solder on the surface.

Step 2: Heating the weldment The tip of the soldering iron rests on the junction of the two weldments, and heats the entire weldment for about 1 to 2 seconds. For soldering components on printed boards, care should be taken to make the tip of the soldering iron touch both objects to be soldered at the same time. Wires and terminals, component leads and pads should be heated evenly at the same time.

Step 3: When the welding surface of the welding piece fed with the welding wire is heated to a certain temperature, the solder wire contacts the welding piece from the opposite side of the soldering iron. Note: Do not send solder wire to the tip of the soldering iron!

Step 4: Remove the welding wire. When the welding wire has melted for a certain amount, immediately remove the welding wire to the upper left at 45°.

Step 5: Remove the soldering iron, after the solder infiltrates the pad and the welding part of the weldment, remove the soldering iron in the upper right direction of 45°, and end the welding. From the third step to the end of the fifth step, the time is about 1 to 2s.

The difference between internal heating electric soldering iron and external heating electric soldering iron

1. The heating element (heating wire) of the internal heating type is inside the hollow core soldering iron tip, and the heating element of the external heating type is distributed outside the cylindrical soldering iron tip.

2. The internal heating type electric soldering iron has high efficiency, and the internal heating type of the same power electric soldering iron is faster than the external heating type. External heating type electric soldering iron, because the soldering iron tip is wrapped in the heating jacket, the temperature drop during soldering is small, and the soldering performance is slightly better.
