Buyer’s Guide

Given the different types of soldering iron in the market, it is essential to buy one that suits the nature of your project. The frequency of use also affects the kind of soldering iron you use. DIYers performing heavy-duty jobs, for example, need cordless irons that provide adequate heat for their projects. Since they drain batteries relatively fast, you need to invest in rechargeable batteries. Here are more ways to help you identify the right soldering iron for your projects:


The Type of Soldering Iron

Soldering irons come in different designs to tackle different handheld jobs. Some irons allow users to work on small openings while others are designed to emit intense heat. Here’s a breakdown of three types of soldering iron:


Basic soldering iron

This kind does not have a temperature control setting but is fitted with an air-cooling feature. Basic soldering irons are designed to work at uncontrolled temperatures usually determined by thermal equilibrium


Temperature-controlled soldering iron

This type comes with a thermostat to help you control the temperature. It makes it easy to maintain the right temperature for better soldering and set the equipment at a high wattage without increasing the temperature


Soldering iron stations

This kind consists of a soldering head with a tip temperature sensor, a control circuitry, an electrical supply. The electrical supply unit allows you to maintain the temperature more accurately. It is this feature that makes them so popular for most soldering projects


Repair or rework systems

These are complex soldering systems designed for professionals working on high-volume projects. The systems consist of a combination of a range of handpieces including de-soldering guns, a soldering iron, hot-air guns, and thermo-tweezers


Source of Heat

Cordless soldering irons are either battery or gas-powered. Gas-powered irons like butane irons heat up fast hence ideal for jewelry projects and automotive use where professionals work in tight spaces without electrical supply. Since their tanks need refilling frequently, it is essential to look for an iron that allows a long period of use between refills and makes the process easy.

Battery-powered irons, on the other hand, have similar performance and power levels as corded soldering irons only that they don’t get too hot for delicate electronics work.


Wattage

It is the most crucial feature to look at when buying a cordless soldering iron. It shows the power output of the iron and allows you to control how fast the iron tip heats up. Most butane irons have a wattage of 20W-40W, making them suitable for DIY projects and those that have a low power requirement.

Look for an iron that can produce low and high watts. It makes it easy to fine-tune it to a specific task. Automotive repairs and jewelry materials, for example, need high wattage. Low wattage irons tend to lose heat faster, hence likely to make inferior connections. Opt for irons that can produce at least 50 watts.


Functions

You also want an iron that comes with a set of tips. They help shape the flame, letting a single iron suitable for small and larger repair applications. Also, look for an iron that comes with a blowtorch function, which enables you to achieve temperatures beyond the average soldering temperature. Their temperatures go as high as 2000 degrees, making them ideal for repairing strip paint, leaky pipes and make crème Brulee.


The Burn Time

It is an important consideration, especially if you are working on lengthy operations. While it is easy to refill the iron with butane or recharge the batteries, it essential to plan the soldering time to avoid getting interrupted. Irons with a burn time of an hour or more make a good buy.


Grounded Plug

If you are working on sensitive electronic equipment like circuit boards, ensure the soldering iron comes with a three-prong grounded circuit. It prevents a buildup of static electricity, which damages electronic equipment. However, if using the iron to fix jewelry and other small items, you may not need a grounded plug.


Ignition Time

Opt for irons that heat up quickly. It should not take more than 30 seconds to produce a flame. Also, consider the melting time.


Level of Comfort

Find an iron that won’t cause fatigue, especially if you are working for an extended period. An iron with an ergonomic design enhances your overall comfort. For example, irons that have slip-resistant grips placed at the temperature and ignition knobs make it easy to grip for long periods.


Safety

Look for EDS-safe products. They are designed to control the flow of static electricity and minimize the probability of electrical shock.


FAQs

(Q) My battery-powered iron does not hold the charge as it used to. What could be the problem?


(A) Battery-powered irons have a life cycle. As such, they are likely to wear out after several charges and usage cycles. Some parts of the tool begin to fail while others loose charge fast. If your iron is not holding charge for a long time, consider changing the batteries otherwise buy another one.


(Q) Which are the best tips for cordless soldering iron?


(A) Look for an iron that allows you to replace tips. Tips come in different sizes and shapes to allow flexibility. Most soldering irons come in conical, chisel, hoof, needle, knife, and tapered shapes. The type of project should help you determine the kind of tip you want.


Conical tips are ideal for applications that involve small electronics as they allow you to maneuver the devices with high precision. They also come in handy for general soldering projects as they are the most common.


Chisel tips are larger and suitable for general soldering applications that need the user to apply a decent amount of solder. However, they are not ideal for projects that require a high level of precision. Hoof tips are great for drag soldering. Their wide surface and concave shape allow you to drag the solder across the surface.


Needle-tip irons resemble conical tips only that they have a finer point. Professionals prefer irons with this kind of tip as it delivers excellent precision. However, it is not ideal for large projects as it is highly specialized.


Irons with knife tips are ideal for drag soldering and making repairs. You may also use them for projects that need less precision.


(Q) Why should I look for soldering irons with an EDS-safety label?


(A) The label ensures that the materials used to make the iron do not produce electrostatic discharge. The accumulation of static charge leads to electric shock.


(Q) How do you refill butane soldering irons?


(A) These steps should help you:


  1. Place the iron on a flat surface with the tip facing downwards
  2. Locate the fill valve and press the nozzle into the valve for 10 seconds
  3. Allow it to settle before you repeat the process
  4. Ensure the room is well-ventilated because butane is highly flammable

(Q) How do ​I remove oxidation build up on the soldering iron?

​(A) If you have been experiencing reduced effectiveness from the iron, clean the tip to restore effective operation by:


  • Adjusting the temperature of the iron
  • Apply flux-core solder to the tip
  • Clean using brass wool or special cleaning tool to remove oxidation

Conclusion

The guide should you choose the best cordless soldering iron for your needs. If looking for a powerful cordless soldering iron, then the SolderPro 120 is a good buy. However, if you are on a budget and want to work on small soldering projects, then the Weller P2C is an excellent option.
