Main Features

The imperfection of WLC100 could be an analog controlling of temperature. All the best-selling soldering stations use a digital display.

But some people like the old-school style. Analog control has some advantages like durability, and it is very hard to damage.


Weller WLC100 40-Watt is a popular soldering station with an adjustable wattage control. Thanks to a special knob, it’s possible to choose the necessary power level (from 5 to 40W). Select a level of wattage and get to work!

There is an ST3 iron-plated copper tip in the delivery set, though you can utilize any compatible tips as well. Additionally, users can connect another soldering iron to the power control unit. Is the iron itself out of order? Don’t buy a new soldering station! Simply connect another one!

An iron holder is another important part of the station that protects you from unintentional contact.

It’s attached to the housing of the unit and can be taken out as well. The sponge for cleaning a soldering iron tip also comes with this station. This will make the process of soldering far more convenient.

Adjustable Tips

Where the Weller WLC100 40-watt soldering station loses some points is in the inclusion of a wider ST3 tip as standard. We prefer the thinner ST1 tip. It provides more accuracy when dealing with smaller electronics such as radio-controlled devices and most circuit boards. The ST3 will be very useful on more easily accessible objects such as tubes or homemade electronic connections.

Conveniently, the Weller tips are replaceable. In fact, the station can use third-party irons—provided they don’t exceed 40 watts in power. This preserves the integrity of the temperature station.

Main Features

User-Friendly Controls

If you’re looking for a perfect balance between price and quality, then consider buying the Weller WLC100 soldering station. It’s a 40-watt soldering kit with adjustable wattage, a sponge holder, and a soldering iron holder.

Sadly, this iron doesn’t feature temperature controls, but that’s only a problem for temperature-sensitive components. And while 40 watts might not seem like a lot, it’s more than enough to maintain stable temperatures. That said, pros who work quickly might be interested in the 80-watt version of this iron.


The first thing that we want to mention about the Weller WLC100 is its price. It’s very affordable and will set you back around $35, which considering all of the features it has (and yes, they are so worth paying for!), isn’t too bad. As far as durability goes, this unit feels like a tank and should withstand many years of use without an issue – there are no loose parts or dodgy welds on the show to be seen anywhere!

This tool offers excellent value when compared with much higher-end tools in other brands such as Hakko FX888D soldering stations and could easily do what most hobbyists need from their own station at home. If your main goal is just general electronics work and you don’t want to spend a fortune, this may be the perfect option for you.

Main Features


How often do the tips for the Weller WLC100 need to be replaced?

About 2 years.

The manual says you can adjust the Weller WLC100 iron from 5 to 40 watts. What range is that in F degrees?

There is no firm correlation between wattage and temperature. Don’t waste your money. Get an iron with actual feedback-controlled temperature control.

You can’t calibrate this for temperature. Tip temperature at any given wattage setting will depend on room temperature and will drop quickly when you actually try to solder using this. Then it takes a long time to come back up to the temperature.

How long does Weller WLC100 take to heat up enough to work with?

Under 5 minutes. Turn the dial to the far right and turn it on. Heats up too much then just turn down the dial.

Would Weller WLC100 be the best type of soldering iron for jewelry making?

Jewelry will use silver or gold solder which requires a torch not a soldering iron. Check micro torches or mini torches, depending on the size of your work

Can I use Weller WLC100 to solder a motherboard?

You can use it to solder any printed circuit board but since you needed to ask this question we would caution you that a modern motherboard has extremely tiny connections and it sounds like you are new to soldering.

We suggest you learn soldering on a simpler DIY kit before you attempt to use any soldering iron to repair or build a motherboard. One tiny blob of solder shorting out very tiny connections and you can ruin any modern printed circuit

Is Weller WLC100 a good station to use for guitar wiring?

No, not this model. It is 120 volts AC, 60 Hz.

Does Weller WLC100 come with a case or bag?

Unfortunately, the Weller WLC100 does not come with a case or bag. However, it does have a secure storage spot for the iron and stands on the base of the station.

If you’re looking for added protection during transportation, consider purchasing a separate carrying case or bag.

This is not a major drawback as the station itself is quite compact and easy to transport without additional protective casing.

What is the difference between a hot air station and a soldering iron?

A hot air station is used for things like removing surface mount components or shrinking heat shrink tubing, while a soldering iron is specifically used for joining two pieces of metal with solder.

Why choose the Weller WLC100?

The Weller WLC100 has adjustable temperature control and a comfortable ergonomic design, making it easy to use for a variety of soldering tasks. It also features a safety stand to hold the hot iron when not in use.

Why is my solder turning black?

One possible reason for black solder is that it may be contaminated with oxidation.

Another possibility is that you may be using a lower-quality solder that has a higher percentage of impurities.

To prevent this from happening, make sure to clean the tip of your soldering iron regularly with a damp sponge and replace the flux when necessary. Also, invest in a higher quality solder that has a lower percentage of impurities.

When should you replace soldering tips?

It is recommended to replace soldering tips every 1-2 years, or whenever they start to show signs of wear and tear such as chipping or uneven heating.

The Weller WLC100 40-Watt Soldering Station comes with a range of interchangeable tips, making it easy to switch out worn tips for fresh ones.

The WLC100 has proven itself to be a reliable and durable soldering station for both hobbyists and professionals alike. Its adjustable temperature control and various tip options make it a versatile tool for any project. We highly recommend it as a solid investment for your soldering needs.

How many watts should my soldering iron be for stained glass?

In general, the wattage of your soldering iron should be determined by the thickness and type of material you will be working with. For stained glass work, a 40-watt soldering iron like the Weller WLC100 is typically suitable as it provides enough heat to properly melt the solder without causing damage to the delicate glass pieces.

The Weller WLC100 also has adjustable temperature control, which can be helpful in fine-tuning the heat for specific projects. In addition, its comfortable grip and lightweight design make it easy to maneuver for detailed and intricate work.

The ceramic heating element also ensures fast heat-up and recovery time, so you can get your project done quickly and efficiently.

Which metal should be avoided while soldering due to health concerns?

While soldering, it is important to avoid using lead-based solder. Lead can be harmful if inhaled or ingested and can cause health problems such as brain damage and reproductive issues. Instead, look for a solder that is labeled lead-free.

In addition to avoiding lead, it is also important to take proper safety precautions while soldering in general. This includes wearing protective eyewear and gloves, working in a well-ventilated area, and not touching the heated tip of the soldering iron.

Can you solder aluminum with Weller WLC100?

While the Weller WLC100 does have a temperature range of up to 850 degrees Fahrenheit, it is not recommended for use with aluminum due to the potential for damage.

For best results, a soldering station with a higher wattage and temperature range should be used when working with aluminum.

Overall, the Weller WLC100 offers reliable performance and an easy-to-use design at a reasonable price point. Its adjustable temperature control and comfortable grip make it a good choice for hobbyists or those new to soldering.
