Soldering Basics – Popular Solder Connections

Learn soldering basics with this hands-on guide to popular solder connections used in electronics, automotive wiring, marine repairs, solar projects, and crystal radios.Several types of popular solder connections shown. These are commonly used in things like cars, boats, trailers, RVs, motorcycle wiring harnesses, solar projects, low voltage yard lighting, drip systems, crystal radio antennas, etc.

The equipment is nothing fancy – it works – but better equipment makes soldering easier and more fun. The big soldering gun is an ultra-cheapie from China – supposed to be 300 watts but I think it’s actually more (note the tip turns red hot in some videos!) The little soldering gun is also low cost, at 30 watts with a 120 watt, 30 second boost in the trigger switch. The solder is rosin core 60/40.

We’ll cover step-by-step demonstrations of key solder joints including the pigtail splice, cross (X) splice, wrapped splice for corroded wire, solid wire antenna joint, butt splice, and strong three-way tap connections. Each method is shown with practical tips for making mechanically strong and electrically reliable joints, from preventing insulation damage to ensuring smooth finishes that won’t puncture tape or shrink tubing. Whether you’re a beginner soldering hobbyist or an experienced DIYer working on cars, trailers, RVs, motorcycles, or low-voltage systems, you’ll find valuable techniques here to improve your skills. Using simple tools and rosin-core solder, this video proves that you don’t need fancy equipment—though the right soldering gun makes the process easier and more fun. If you’re into DIY, science, electronics, technology, mechanics, or retro projects like crystal radios, this tutorial will help you build safer, stronger, and longer-lasting connections.

WARNINGS:
– Soldering can be dangerous. If you do not know soldering safety, learn it or don’t solder.
– Never solder live circuits of any type.
– Soldering house wiring, power wiring, etc. is outside the scope of this video. That should be left to professionals only.
– Electricity can cause damage, fires, burns and death. If you don’t know about electricity, learn before doing.
– These are demonstrated for hobby work, low voltage – low amperage applications. NOT for mains voltages or currents or similar.
– Never use lead type solders where it will come in contact with food or drink or where it will come in regular contact with people.
– Lead is toxic. Take care to ensure that the byproducts / waste are contained and disposed of properly. Never hold solder in your mouth. Have proper ventilation.
– This is for hobby soldering only. Industrial users have more stringent requirements for industrial or large scale soldering operations.
– This is not all inclusive. If you don’t know, get training before continuing.
