The best soldering iron for guitar repairs will vary depending on your need but if you are a hobbyist that needs to repair your own gear at home, the Weller WLC100 40-Watt Soldering Station is a great start. Its adjustable wattage makes it versatile and it comes with a soldering station making it very convenient. For the guitar repair shops out there, I recommend the Weller WES51 Soldering Station. This machine is a workhorse and can handle both light duty and heavy duty projects.

Whether you are replacing the pots or upgrading the pickups in a guitar, you will need a good soldering iron. Repairing your own guitar gear can be very gratifying but that is not the only great thing about owning a soldering iron.

Before I started repairing the electronics in my guitars or replace parts in my guitar amps, I was building my own guitar cables for much cheaper than purchasing them from a store. When I decided to start making my own guitar cables I set out to find the best soldering iron I could for guitar repairs and cable building.

I learned pretty much everything there was to know about soldering irons and what made some better than others and the different types there where. Before then, I just thought they were all the same and I should just grab a cheapest one from the store. After reading about cheap units overheating electronic guitar components I quickly changed my tune, no pun intended.

Below is the guide I put together and is based on all of my research. It should help anyone out there looking to get into guitar repair and other musical gear repair. As you can imagine, the needs for guitar repair are much different than needs for soldering irons for stained glass.


How To Choose: A Guide to Soldering Irons for Guitars

The main purpose of a soldering iron is to apply concentrated heat to the pieces you intend to connect and melt the solder bonding the two together. Most of the things you will need to solder in guitar repair are broken wires, pots, and the occasional transistor or capacitor. You will also need a soldering iron for building guitar pedals if wanted to do so. I’ll quickly go over the important attributes and details so you can choose what will work best for you to start repairing guitars, building pedals, or making guitar cables.

Soldering Iron For Guitars: How Should They Perform

  • WATTS: The wattage of a soldering iron is a general indicator of its power. However, more power is not always better and it is not an indicator of performance. It is one aspect of how quickly the iron can get up to temperature but heat retention and recovery are also affected by other components.

    The most common soldering iron watts used in guitar repair is between 25-50 watts. Lower power being 25 watts and used for the more delicate guitar electronics parts like pots, capacitors, and transistors. The higher watts are used to solder heavier duty parts like thick braided wires and guitar cables.

  • ELEMENT: There are two types of elements used in soldering irons, a ceramic element and a Nichrome wire element. The Nichrome wire element is a resistance wire that uses electrical resistance to conduct heat. The ceramic element heats based on the same principle but has different characteristics.

    Nichrome Elements used in soldering irons are usually bigger and heat up a larger metal body. This larger body conducts heat to the tip. This large body means the Nichrome equipped iron can store more heat and the tip temperature will drop more slowly. This style should supply more sustained heat enabling longer sustained use in theory.

    Ceramic Elements used in soldering irons are typically smaller and heat up the ceramic body much closer to the tip. The ceramic conducts heat to the tip and translates to much faster heating times but less sustained heat. Losing too much heat can lessen the ability to liquefy the solder over time when continuously feeding it. This is really dependent on many factors though and not a hard fast rule.

    If you are wondering which is better, that is a trick question. For smaller units and light to medium uses, the difference should not really impact most people. In guitar repair, either will work just fine. This becomes more a matter of preference but again, take into account the type of soldering you will do; long continuous runs requiring sustained heat like that offered by the large Nichrome element, or short and quick beads which ceramic elements handle nicely.

  • TEMP CONTROLLER: Though marketed as a temperature controller, these units actually only regulate the wattage sent to the element. Usually the temperature at the tip will constantly vary which may not be great while working. When choosing a unit with a temperature controller, it always best to buy a higher quality unit when soldering delicate electronics.

Soldering Irons: Other Things To Consider

  • TYPE/STYLE: Handle type soldering irons are available in two different styles or configurations. The pencil style is just a straight unit from handle to tip. The hatchet style is bent up to 90 degrees where the handle and element meet giving the unit an “L” shape. This re-positions the center of gravity closer to the hand offering ergonomic feel and working angle.
  • TIPS: There are many different tips available for irons. There is a chisel tip, an angle chisel, conical, and point tips. All of which available in varying sizes. The pointed tip is going to be best for most of your guitar repair work involving pots and switch contacts. A chisel tip is going to be best for guitar cables or large wire soldering.
  • ACCESSORIES: When purchasing your soldering iron for guitar repair, it is good to have a few accessories on hand. A cleaning sponge or a brass coil is a must to keep you tips clean and freshly tinned. An iron stand is also a must have to keep the it accessible and shield the hot parts from accidental burns.

Quick Tips To Soldering Guitar Parts and Accessories

Learning to solder is very easy and if you are interested in reading a more detailed guide, check out the Seymour Duncan guide, How To Solder. If you prefer to just get right to it, there are just a couple of tips you need to know before you start soldering on your expensive gear.

SOLDER

When purchasing solder you should look for a 60/40 Rosin-core solder for guitar jobs. This solder is a mix of 60% tin and 40% lead, and has rosin flux in the center to ensure that the solder melts and flows easily and quickly. It also ensure a good bond between the two materials you are connecting. this is the most common solder you can find.

The other option, albeit expensive, is a 3%-4% silver solder. This is the highest quality lead based solder and a halogen-free flux is gentle on precious metal surfaces and the melting temperature is extremely low (356°F/180°C). This helps to not overheat delicate parts.

It is also good to use liquid Rosin Flux and brush the contact points with it before soldering them. This ensures the solder will stick consistently and smoothly to the solder points.

OTHER TIPS

  • Always let your iron heat up completely to ensure the solder melts quickly and runs smooth.
  • Heat the main contact point first before soldering.
  • Apply rosin first if you are using it.
  • Tin (coat with solder) each connection point first if possible.
  • Don’t use a higher than necessary temperature.
  • Always keep a solder sucker or desoldering wick handy.
  • Work in a well ventilated area.
