Technically only 2 things are required to solder, a soldering iron and solder (there are even some soldering strips that you can activate with a match, but that's getting a bit out there). So let's start with soldering irons. After that we'll look at some clamping options to hold things in place and then some other tools you might want to consider.
Irons can range from the cheap (sub $10) versions that plug directly into the wall up to thousands of dollars for high end soldering and rework stations. If you are just getting started, you don't need to spend a fortune to get a reasonable piece of equipment. At the end of this section are some soldering options for emergency and field use.
Save yourself some frustration and don’t buy a cheaper soldering iron from Radio Shack or Harbor Freight. Especially if you are just starting out, at least invest in a descent tool. For $22 you can get the Velleman VTSS5U adjustable temperature soldering station. It has an analog temperature control with no display so you don’t know exactly where it is set, but at least it’s adjustable.
Hakko FX-888D digital soldering station ($99) is an excellent tool for hobbyists. This is the iron I'd recommend if you have any intention of soldering more than one or two small projects. This kit comes with a pair of the best cutters you’ll ever use. I love my Hakko cutters. I have several of them and I use them all the time.
For emergency use (only) there are some alternative soldering irons:
- A USB powered one for $9 (use it with a USB battery pack)
- A 12v powered unit for $13
- A butane powered unit for $19
If you plan to solder much at all, you are going to want some way to clamp things in place while you solder them. This is true whether you are soldering wires together, soldering parts on a board, or soldering wires to a connector. Again, it doesn't have to be super expensive to be effective. Start with putty and clothespins and then move up to a vice if you find you are doing more soldering.
Plasti-Tak (poster putty, adhesive putty, mounting putty, reusable putty) is a great and cheap way to hold parts to boards, hold boards still, or hold wires and or connectors in place while soldering. The cheapest you can find should work just fine (Elmers $4, or Duck $2 add-on). Some people use Silly Putty instead. That works too but I prefer the extra stick and stiffness of the poster putty. Try this video if you want to see it in action (“Blu-Tack” is the same stuff).
Wooden (not plastic; they melt) clothespins make a great inexpensive clamp for holding wires, boards, or small parts when soldering. You can cut the angled ends off to make a ‘flush’ or ‘flat’ face to your “clamp” (see picture above). Combine clothespins with reusable putty (previous tip) and you have a very portable, inexpensive, and versatile clamping system. This guy made a fixture to hold the clothespins in place. You could do the same with a piece of scrap wood (1x6, etc.) for essentially free.
The Stick Vise ($30) is a great little portable vice for soldering. Takes almost no space and you can 3D print your own jaws if you are so inclined.
There are some 3D printable clamps you might consider as well.

- MobilVise (a portable, printable version of the stick vise)
In addition to clamps, there are a number of other tools you might consider. Two of the most useful are some sort of pliers and a soldering mat.
Hakko long nose pliers ($9) are just a pleasure to use. The jaws close nice and flat and they hold parts very nicey.
A silicone mat ($7) is one of the best investments you can make. They are very inexpensive but make it much easier to work. It helps you keep track of parts and, unlike your kitchen table, you can’t burn the mat with your soldering iron.
