How to Solder and Heat Shrink Electric Wires with VersaTip & VersaFlame

Start by stripping about 0.39 inches of insulation off your wires using a wire stripper to reveal the copper. Don’t forget to slide a heat-shrink tube onto one of the wires before moving on - you’ll need it later. By the end, your wires should be ready to roll!

Pro Tip: Work in a well-ventilated area and throw on some eye protection.

Pop on the soldering tip to your VersaTip and and give it a quick wipe on a damp sponge while it’s still off to remove oxidation and ensure efficient heat transfer. Heat the tool to a moderate level around 599°F to 698°F - just hot enough to melt the solder without scorching it.

Hold the wires together, feed the solder wire to the joint, and heat it from underneath until the solder melts and flows smoothly.

Pro Tip: Avoid staying too long, or you risk burning the wire.

Test your connection by giving the wires a gentle pull to ensure they are securely bonded. Once you are confident it’s strong, slide the heat-shrink tubing over the exposed wires. Now, grab your VersaFlame and set temperature between 194°F and 302°F. Hold the torch about 1.18 inches​​​​​​​ away, and move it back and forth over the tubing. Watch closely as it shrinks snugly around the wires - don’t overdo it to avoid damage.

Pro Tip: The VersaTip with its hot air tip works just as well for this job!

Make sure your tools are off before putting them aside. Give your soldered joint a quick once-over. Is it strong? Is the tubing snug? And there you have it - a solid, secure, and professional wire connection! Easy peasy!
