Soldering gun vs. iron: determining which is better

Beginner hobbyists in the soldering process are unsure of which tool to use for their projects: a soldering gun vs. a soldering iron. The tips in the following guide will explain how to utilize two distinct soldering equipment.

Before purchasing a soldering gun vs. iron, ensure that you examine the technical specifications. To begin, let’s define the terms.

Usage of soldering gun vs. iron

A hand instrument called a soldering iron is employed to heat solder to high temperatures over the alloy’s melting point, usually with electricity. This makes it possible for solder to transfer effortlessly between the workpiece material that need to be linked while utilizing soldering irons.

In electronics assembly, a soldering iron is most frequently used for installation, maintenance, and a small amount of production work. Other soldering techniques are used on high-volume production lines.

For soldering joints in sheet metal items, a large soldering iron can be employed. Other applications of soldering irons include plastic welding and pyrography (carving designs onto wood) as an alternative to ultrasonic welding.

A soldering iron and an electric soldering gun can be used interchangeably. Guns lack a high-frequency converter but do feature a step-down transformer.

A soldering gun’s body is quite similar to a soldering iron’s body. Guns may operate much more quickly and don’t require as many breaks as transformer soldering irons do. This tool is used to solder all metal surfaces that need to be soldered in heavy-duty jobs.

The soldering gun offers good conditions for working with identical parts because of its special action mechanism. The primary applications of a soldering gun include the creation and maintenance of gadgets, home appliances, radio circuits, cable lugs, and other items.

The main list of components of a soldering gun includes the following:

• the tip is the main working component that comes into contact with the desired soldering location
• a tool holder that resembles a gun’s handle for a secure grasp when using an instrument
• the tip must be heated by the heating element
• the soldering tip is connected to the power grid by a cord with a connector and cable lugs
• the device’s little shaft is a component that joins to the tip

In contemporary types, chrome and nickel are mostly used to make the main heaters. Under the impact of electricity, it warms up. The solder will melt at the regular heating temperature.

Since copper is a metal that conducts heat well, the core of a soldering gun is typically constructed of copper to ensure that heating occurs as rapidly as possible. The tip typically resembles a wedge.

Remember that a soldering gun has a special design and operates at low voltage. Because of this, it has high efficiency. Electricity costs can be decreased by using soldering tools with ceramic tips. The only time current passes through the tip is when soldering.

This is distinct from the standard practice of using a soldering gun. The remaining variations are primarily caused by the existence of a frequency converter.

There are some details you must be aware of and some questions you may ask:

• Can I use a soldering gun for electronics?

When the button is released, the soldering gun produces an electromagnetic spike, which can be problematic for electronics that are susceptible to electromagnetic fields. When a high-efficiency LED is soldered, the spike can be seen while the LED flashes.

• Why should a soldering gun not be used for electronics work?

The use of a soldering gun for joins on printed circuit boards can result in too much heat being provided to the joint, harming the circuit board, because the temperature of the tip is not automatically adjusted.

Over time, the copper tip must be replaced as it gradually dissolves in the solder.

What is the difference between a solder and a soldering iron?

Compared to soldering guns, a soldering iron is easier to wield while performing soldering jobs. Therefore, it appears to be more adaptable for soldering light electronics. Heavy-duty tasks benefit greatly from larger firearms. The firearms require less energy and operate more quickly.

The technique used to heat the tip represents the most significant basic difference. The tip of a traditional soldering iron with a heater made of ceramic or chrome is kept as far away from the electric current that runs through the heater as is practical. The tip of a soldering gun acts as a conductor for the heat generated by the electric current.

The tip of a soldering gun can provide an electric shock, which is its major flaw. Such a soldering gun is excellent for connecting common wires, but it can also quickly disable microcircuits that are sensitive to high voltage.

Quick heating is one advantage of a soldering gun vs. a soldering iron. When using a soldering iron outside or in chilly conditions, you must take this into account. Under these circumstances, a regular soldering iron with a chrome heater will cool down rapidly and be unable to evenly warm the soldering site.

How does a soldering iron work? Typically, soldering irons have a pencil or wand-like shape.

Handheld. A soldering iron’s grip has a rubber coating for comfort and is heat-resistant. While they are easily grasped in one hand, a second hand may be required to steady the first.

For more delicate work, reduce the heat. They are ideal for smaller projects because they typically have temperature control and considerably lower power than soldering guns.

The same temperature, no temperature control. Since they lack a switch or trigger like a soldering gun, they will start to heat up as soon as you plug them in and turn them on. They will remain completely heated until you turn them off.

The following are some suggested iron soldering projects:

• circuit board
• electricity cables
• automotive wiring
• simple DIY projects

A soldering iron may be used for a wide range of applications because it is so much smaller and use less wattage than soldering guns. It also has low enough temperatures to protect fragile electronics.

Pros and cons of a soldering iron

The benefits of soldering irons include:

Numerous options

Compared to soldering guns, soldering irons are significantly more prevalent and are available in a range of sizes to suit different demands.

The majority of best soldering iron options also offer a variety of recommendations that may be used for numerous undertakings. You will be in a better position the more options you have.

Weight

They are easier to work with than soldering guns because they are lighter, especially when working for extended periods of time. When deciding between an iron and a gun to finish a task that will take several hours, the iron is usually the better option.

Compared to the gun, the tiredness will be minor.

Workflow

Irons heat up much more slowly than guns do, but once they are hot, they maintain their temperature longer than firearms do.

The majority of the time, you can switch them on and leave them running throughout your job. This permits continuous workflow and more effective project completion.

But by no means is a soldering iron flawless. There are a few things to take into account in terms of drawbacks as well:

Only for small soldering projects

Only minor projects like those that are mentioned above are suitable for a soldering iron. Soldering irons cannot withstand larger soldering jobs, which is what soldering guns are made for. It is unable to generate the heat required for the majority of big or industrial applications.

Inefficient

A soldering iron vs. a soldering gun heats up very slowly and uses more heat as a result. To avoid having to wait while soldering irons heat back up, it is best to leave them on once they are heated for the duration of your task. They use a lot more energy than soldering guns, by far.

How does a soldering gun work (what are the pros/cons: soldering gun vs. iron?). In terms of appearance and functionality, soldering guns resemble handguns.

Handheld. They have a trigger switch that you pull with your index finger, and they are easily held in one hand. When the trigger is pressed, a loop of copper wire at the gun’s tip immediately heats up.

The body is like a drill. A portable drill and a soldering gun share a similar body. When the trigger is pressed, a transformer inside the gun’s body is turned on. This enables the tool’s tip to generate heat from the gun’s electrical power.

Extreme heat. You can melt your solder and join your metals together when the gun’s tip heats up.

And again, extremely hot soldering is not the best method for delicate electrical circuit boards. They are considerably more appropriate for industrial use.

These are powerful machines built for heavy-duty jobs that need a considerable amount of heat with little disruption to workflow.

They are a fantastic alternative for anything larger than a typical circuit board. They are also excellent for anything that demands more power than their soldering iron counterparts, which are low-powered.

High power

With a power range of 100 to 240 watts, a soldering gun is a great option for any of the larger projects indicated in the section above. For such big projects, the ability of the gun to get hotter often increases with power.

Quick cooling and heating

Instantaneously upon depressing or releasing the trigger, these tools begin to heat and cool. It is a tremendous advantage to not have to wait around for it to heat up because of this. It’s also great for outside soldering in cooler conditions, as guns may not necessarily be affected, but irons may be.

Permanent workflow

When it comes to your project’s workflow, a soldering gun is fantastic. Because of their quick heating and cooling, you can switch them on and leave them on. You don’t need to frequently turn them on and off and then wait for them to reheat if you only occasionally need the high heat, this provides more efficient job completion.

Unreachable places

The solder gun can be used with one hand, making it more practical for working in tight places or gaining access to challenging locations. Since they exist in various sizes, a smaller one would be ideal under these circumstances. The fact that it fits in strange locations where you can only use one hand does not imply that it is ideal for tiny tasks.

Efficiency in energy

Most soldering guns quickly heat up and cool down, which is fantastic for your electric cost. They are very effective at converting electrical energy into heat. They don’t require a lot of energy to heat up, and when not in use, they cool off to conserve energy.

Although we’ve already covered a lot of the advantages of a soldering gun vs. a soldering iron, you need also be aware of some disadvantages when selecting a tool for your next project. Here are a few drawbacks of utilizing a soldering gun rather than an iron.

Weight and size

Irons are much lighter than soldering guns. They have much heavier components put in because they are made for bigger projects. Although they are fine for the intermittent tasks for which they are frequently employed, they can become rather heavy when worn for extended periods of time.

Soldering guns might be a little awkward to use because they are bigger than soldering irons. As a result, they are frequently more difficult to control. Keep in mind that they can fit in odd-shaped areas, but not necessarily tiny ones.

Chance of electric shock

It should be emphasized that the tip is hazardous even though safety guidelines and warnings are typically included with soldering guns.

By contacting the gun’s tip, you run the risk of burning yourself and receiving a mild electric shock. Copper wire, a superb electrical conductor, is used in its construction.

Replaceable tips

In addition to the risk of electric shock, soldering guns require much more frequent tip replacement than irons do. The copper will need to be replaced multiple times as your work goes on because it tends to deteriorate quickly during large soldering tasks.

To prevent having to put off a project for a few days to receive more advice, we advise always having a few recommendations on hand.

Checklist for soldering irons and guns

Now that you are aware of the fundamental distinctions between a soldering gun vs. soldering irons, you might be prepared to choose a tool. Simply said, use an iron for delicate tasks and a pistol for heavy-duty ones. By this time, it should be clear how the two vary.

How do you choose the right instrument, aside from industrial vs. delicate? What actions should you do to make the best decision possible? You must be aware of the essential characteristics and the criteria you use for this approach.

• Power range

When choosing the right tool, one of the most crucial considerations is the wattage. Most soldering irons have wattages between 20 and 60W. Generally speaking, the iron is better the higher the wattage. Circuit boards and other electronics can withstand up to 60W.

Wattages for soldering irons range from 100 to 240W. These are not appropriate for little gadgets because of their substantially higher power. The same principle holds for industrial jobs: the higher the wattage, the better.

• Temperature control

It is quite useful to be able to regulate the temperature of your soldering gun vs. a soldering iron. A soldering station with a variety of tools and temperatures may be necessary if you are performing numerous distinct tasks on the same project. It’s crucial to know the temperature before purchasing if you just use one tool.

You should conduct a study before buying the tool because many guns and irons only have one temperature. You have greater flexibility if you plan to use a station.

• Replaceable tips

You won’t need to change the tips on soldering irons as frequently as you would on guns. However, it’s crucial to understand how to replace them, where to buy them, and what’s accessible. The very last thing you want to happen is to buy a tool only to discover later that replacement tips are tough to come by.

Pro tip: it’s a good idea to get some extra tips at the same time you buy the tool. You’ll be able to finish your soldering task faster and with less angst if you do this. Nobody wants to put their current task on hold to go buy additional tips or to place an online order and wait two days for them to arrive.

• Warranty

You may want to think about one that comes with a guarantee, just like with any electrical or power tool purchase. In order to assure that their consumers can have problems repaired if they do, many tool makers include warranties with their products.

• Pricing

Last but not least, you should think about how much the soldering tools you wish to buy will cost. The more expensive price tag typically equates to a superior product, as is the case with most commercial goods. Spending more money on superior tools is a good idea if you want to solder frequently.

Conclusion

We hope that most of your concerns regarding making the right soldering tool selection are now allayed. Making the best decision between a soldering gun vs. a soldering iron will be made easier with the help of our suggestions and comparisons.
