Durable, Easy-to-Control Pencil Iron
At the heart of the WLC100 Soldering Station is a high-quality lightweight pencil iron with an ST3 iron-plated copper tip. To ensure that you can work comfortably for long stretches of time, the iron has a cushioned foam grip that sits comfortably in your hand as you work. It has a replaceable heating element, so you can continue using the same iron for a long time to come.

Easy-to-Adjust Variable Power Controls
Unlike many basic soldering kits, which can be difficult to adjust, the WLC100 features a variable power control that lets you adjust the power level from five to 40 watts with a simple turn of the knob on the base unit. This lets you choose the precise setting for each unique job that you tackle. The base also includes a "power-on" indicator light and on/off switch to help keep you from leaving a hot iron on accidentally.

The workstation also provides a built-in iron stand to keep your workspace organized and a natural sponge tip cleaning pad to keep your tip ready to go at all times.

High-Quality Accessories for Dependable Performance
The WLC100 includes an ST3 iron-plated 1/8-inch screwdriver tip. Weller also offers a wide array of compatible ST series tips to perform a variety of applications (additional tips are sold separately).

All Weller tips are constructed of solid copper and plated with iron, as well as nickel and chromium to protect against corrosion and solder creep, helping to ensure that your tools perform reliably over time. Additionally, Weller tips are pre-tinned with tin/lead solder.

This WLC100 Soldering Station is UL-listed, which means it has been tested and meets independent safety standards. It is backed by a one year warranty against manufacturer’s defects in material and workmanship.

Soldering iron, ST3 tip, and base unit with built-in iron stand.

I've had this iron for ten years now. The level of use it's seen has varied up and down, depending on how much time I had available to spend on my electronics hobby. The iron itself is absolutely fine for, you guessed it, hobby and DIY use (no problems with it not being ESD safe, and I've soldered a lot of semiconductors). If I ever need to do a higher volume of work I will upgrade to a WES-51 temp controlled station, but for now this continues to fit the bill quite nicely. The tips are long-lived if you take care of them (keep it tinned even while sitting in the holder, try not to bash it on the holder when you put it in, don't leave it switched on if it won't be used for a while). The standard tip is too big for electronics use and must be replaced with something smaller. For a long time I had a medium-size tip on there and it seemed to function well between 3 and 4 on the heat control, depending on the size of the work. With this station you need to pay quite careful attention to the way the solder flows when you heat the joint, if you want to produce high quality solder joints. The solder should become fully liquid and flow into and around the joint area on its own, without needing to be spread around the sides and back. If not, the temperature isn't high enough. On the other hand, don't set the temp higher than it needs to be or you will shorten the life of the tip and may damage the component you are working on. Remember this and you will quickly learn where the 'normal' setting is and when to turn the iron up or down a bit in response to larger or smaller work.Read more ›

I use a Weller WES51 Weller WES51 Analog Soldering Station, Power Unit, Soldering Pencil, Stand and Sponge at work doing work on circuit boards. I've got probably 24 hours of use on the WES51 so far. I bought the WLC100 for use at home on hobby and DIY work because it is half the price of the WES51. The biggest differences I have seen being: The WLC100 takes MUCH longer to reach operating temperature(but the WES51 only takes 20-30 seconds) and doesn't have the same ability to hold operating temperature when doing large joints. With that said, it's as solid a unit as I've used besides my WES51 and can get every job done that should be needed by a hobbyist. If you are planning to use this for long periods of professional work, I suggest going stepping up, but for smaller jobs this is the station to get.

For the same price one can get a "Professional" series Weller iron (like this one) with constant tip temperature, or a less known brand temperature-controlled station (like this one) that will be much nicer to work with.

Weller quality and durability.

Price is too high for a simple iron without temperature control, the "power control" knob works like a simple light dimmer - with no feedback from the tip, so the temperature will be jumping up and down while you work.

Side notes: for pleasant work experience and good quality soldering one needs to keep the proper tip temperature - it can't be too low or too high. Note that in both extremes the solder will visibly melt, but the quality of the connection will suffer. When the iron is too cold: you are likely to get "cold solder" joints that look fine outside but lack internal integrity and often drop the connection soon. These are hard to troubleshoot.

If the iron gets too hot, you may burn the copper traces and they will break off the PCB, you may overheat electronic parts, and (most annoying to me) you burn out the flux before it does its job. Ironically, using too hot iron may also result in "cold solder" connections. This happens because the flux will go in smoke before it reaches the soldered surfaces to clean them and make the solder stick properly and permanently.

The only way to ensure correct soldering temperature is to use controlled iron with feedback from the tip (very important). The WLC100 has only appearance of "control" but you can't set and hold the temperature. It is as good as the cheapest iron from Sears or Radio Shack that cost five times less.

Many years ago when I got this iron, it was only $30, and I see it has almost doubled in price, but STILL FAR BELOW the cost of the other Weller soldering iron stations!

And there is really no other reason to get the other ones, when one of the elements goes bad on the other ones, you have to pay more than the price of this whole station just to replace the element! This one doesn't have any element, you just replace the tip, which you can get at any Radio Shack for a dollar or two tops. And I still have not needed to replace the tip on this one after years of use, since I keep the tip nice and tinned.

This heats up nice and fast, is always reliable, just as good as any of the BLUE ones that cost three and four times the cost that the same company sells, and has never let me down.

Get it now, before they raise the price any more!

Once you get it, it should last a lifetime.
