Get Better At Soldering: 6 Tips & Tricks
I remember learning how to solder like it was yesterday. What I remember most is just feeling awkward, like watching a baby deer trying to walk for the first time. Soldering is one of the most critical skills to have when working on your guitar. I always hear people say “I’m not good at soldering” or “I can never do that.” Because of this, you see those cheap “clip-on” harnesses and connections. That’s cool and all, but what happens when that connection fails?
I understand it seems like a daunting skill to learn, but it’s really easy when you get the hang of it. At Fralin Pickups, we solder all-day, every-day at the shop. We’ve learned a few tricks to help you, so, here they are:
Use The Right Soldering Iron.
Yep. This is a big one. There are many types of soldering irons out there, and choosing one can be a little confusing. We have a few varieties laying around the shop, but our main workhorse is the Weller® WD-1 and WP-80 pencil. Is this a little overkill for the home enthusiast? Definitely. However, if you’re going to be soldering a lot, we really recommend this model for a few reasons: Weller® makes excellent products, and this model is a Temperature Controlled Soldering Station.
Having a temperature-regulated iron is helpful because you might be just attaching a wire to a switch one minute, then the next you are heating a baseplate or back of a pot, which disperses more heat. Cooking your solder too hot can damage parts of the guitar: it can make the solder too “watery” and if it drips, it’s easy to ruin a 5-way switch with it. If your soldering iron or pencil doesn’t get too hot, you’ll be there forever waiting for the back of the volume pot to cook, and you might get a Cold Solder Joint.
Here’s a useful tip: DO NOT USE SOLDERING GUNS AROUND PICKUPS. Soldering Guns are so powerful that you can degauss, or de-mag your magnets in your pickups. We never use these – we always make sure we use a Soldering Pencil.
Use the right solder.
This one again is a no-brainer. We use 44 Gauge Rosin Core Leaded Solder. Leaded solder is a lot easier to work with than unleaded or silver solder. You’ll get more consistent results and a reliable electrical connection with it.
NOTE: Always wash your hands after soldering with leaded solder. It contains lead. It’s poisonous when you ingest it, so don’t!
Create a Mechanical Connection.
The best electrical connection is a Mechanical Connection. When soldering leads on to pots or switches, make sure you put a 90-degree angle in the wire before feeding it through the lug. This makes sure that the wire is secure and able to withstand some tugging.
Pre-Tin Your Leads and connections.
Pre-Tinning is as simple as getting solder on your wire and lug (or whatever you’re soldering to) before making the connection. This is a simple and easy way to make sure your connection is complete. A Cold Solder Joint may look like it’s connected, but in reality, it is not. There might have been some oil or gunk on your lead before making the connection, and the solder isn’t connecting everything.
Pre-Tinning your lead and your Lug of your switch or pot will make sure that all that gunk is burned off, and when you heat the joint, both soldered items join each other in harmony.
Pliers and tape are your friends.
I’ve burned myself countless times trying to hold that wire in place waiting for the solder to cool (I’m pretty immune to the pain now). Don’t be like me, be smart! Use pliers or some tape to hold that wire in place while the solder sets temporarily. This is especially helpful when you’re holding ground leads to the back of a pot, where residual heat can keep those pools of solder runny for a bit.
Give yourself ample space and planning.
If you’re first learning how to solder, I can’t stress enough how valuable space is. Having enough elbow room is so important to have a clean installation job. Soldering pickups into a pickguard? Unsolder the ground and hot connections to the jack and work on just the pickguard. Get all unnecessary items out of the way so you can quickly and cleanly get those pickups in the guitar, without the headache.
Planning is equally as important: make sure you have a diagram laid out and all the parts handy. Take pictures with your phone of the wiring in case you forget where that wire goes. Draw a quick sketch before you dive in. All these little tips are handy when you start learning how to solder and will make your installation or repair a lot easier to do. Well, there you have it! We hope this helps you have a little more confidence with the iron in hand.
