A soldering iron can be very useful for a variety of home and DIY purposes including fixing broken circuit boards and electronics, making jewelry, arts and craft projects, science projects and much more. However, not all of us know what a soldering iron is, how it functions, or what brands to look for when making a purchase decision. That’s why we’ve put together this buying guide to answer some common yet essential soldering iron questions amongst hobbyists and professionals alike.
What Is a Soldering Iron?
A soldering iron is primarily a tool featuring a metal tip that can get extremely hot. It can go up to 700 degrees Fahrenheit, though a good iron allows the user to adjust the temperature. An electrical current that goes through the resistive element produces the heat, which is then transferred to things like PCBs’ pads, transistor leads, and wires Once dedicated to repairing television and video game consoles, soldering iron are now a common sight in DIYers’ toolkits. They are even being used to carry out repairs, production work, and limited installations on assembly lines (electronic ones). Because soldering irons remain hot for a reasonable period, they don’t need to be switched on or off in intervals, which enables smoother workflow.
How Is a Soldering Iron Different from A Soldering Gun?
Soldering guns offer more power voltage (100-140 watts) than soldering irons. Also, they enable the user to work in confined spaces (their tip is shaped like a copper wire’s loop, which for greater flexibility), which is far more challenging to achieve with soldering irons. Moreover, they’re useful for both metal projects and massive connections requiring lighter touches. They are typically used for larger tasks like electrical connections and heavier wire and other professional work. In contrast, soldering irons are lighter than soldering guns, which makes them a better choice for projects that require soldering over long periods. Additionally, they offer flexibility as there’s a wide range to select from; DIYers can invest in larger irons for heavy duty jobs while small irons work well for lighter electronic installation/assembly projects. And unlike soldering guns, soldering irons don’t need to be switched off or on repeatedly, as they stay hot longer.
Here’s a breakdown of each:
- For heavier workpieces
- Offer more voltage than soldering irons
- Don’t have a lot of varieties
- Quicker to heat up
- Lower-power projects
- Contain less voltage than soldering guns
- Have a lot of varieties and types
- Slower to heat up
Varieties of Soldering Irons
Vendors manufacturer a variety of soldering irons to tackle varying handheld jobs. Some come in a design that enables users to work in small openings, while others focus on designing irons that emit intense heat to deliver quick melting points. Below we’ve listed a few of the most common types of soldering irons that electronic professionals often stock.
- Temperature controlled soldering irons: A thermostat is placed inside the iron to provide some temperature control. The function enables the right temperature to be maintained, which allows for better soldering. A higher wattage can be utilized for scenarios where the heat is drawn from bits without too high a temperature for soldering.
- Basic Soldering Irons (Air Cooled): The most basic soldering iron model doesn’t include temperature control apart from the air’s cooling impact and any task the iron may be used for. Basic models of soldering irons are designed by manufacturers to function at uncontrolled temperatures that are usually determined by thermal equilibrium.
- Soldering iron stations: These consist of temperature, control circuitry, a soldering head with a tip temperature sensor, and an electrical supply. The station stores enable the user to store the iron when it’s not being used.
What to Look for Soldering Irons: Important Factors to Consider
While soldering irons aren’t a regular buy for beginner do-it-yourself enthusiasts, they can quickly become an integral part of their toolkit as soon as they help accomplish a few key tasks. However, several factors should be accounted for before buying a soldering iron. To that end, we’ve compiled a list of the purchase factors that apply to both DIY hobbyists and electronics professionals.
Interchangeable tips: The ideal soldering iron features an easily replaceable tip. The tip, which is also known as a bit (in the world of soldering irons), comes in several shapes and sizes to offer flexibility to the buyer. The most common shapes include fine conical, chisel, tapered, and pyramid. Consumers should identify which type of projects they plan to work on before deciding what tip to buy.
Wattage rating: A rating of 20 to 50 watts is desirable. However, the wattage doesn’t contribute to how hot your iron will become. Instead, it determines how quickly it can heat up and how quickly it can come back to the standard operating temperature after a solder joint is complete. A soldering iron with higher wattage is capable of holding a stable temperature for an extended period while the user solders a connection. Also, it can re-heat itself quickly in between.
Ground Power Plug: A ground power plug of three-prong is recommended, but it isn’t a necessity. The grounding helps secure the iron against static discharges that hold the ability to render sensitive electronic parts useless when they’re soldered.
Temperature Control: The best soldering irons will have a feature that allows for temperature control. The function varies from thermocouple that combines with station circuitry to enable users to adjust the temperature of the tip, to controlling variable power control’s temperature range. Advanced models also include a thermostat that switches on and off automatically, depending on the quantity of power needed for specific tasks.
Brands: Several popular electronic brands, like Weller, create soldering irons, so merely choosing a branded model instead of an unbranded soldering iron is a great way to ensure product durability and high-quality. Potential buyers should look into brands that hold a good track record for manufacturing top-notch soldering irons. Branded soldering irons rarely overheat, offer firm handling, and are extremely easy to grip and use.
