How To Solder Copper Wire Together
Hold the solder in place for a few seconds until solder starts to flow.
How to solder copper wire together. If the wire is stranded twist the strands together with your fingers. Make seven or eight turns and cut the excess of the wire. Connect together stranded wire and solid wire as shown in the third picture Use a thin solid wire 28 AWG-30 AWG and wrap it around both wires.
Bring both stripped ends together like shown in the image below. Strip off about 1 inch of the insulation from each end of the two wires using the wire strippers. Twist the wire ends of the two points to be soldered together into a J shape.
Cut the two wires in order to make sure that the copper core of the wire is not corroded or contaminated inside see image below. Think of holding a pen or pencil holding the soldering iron at an angle so that the heat will make it flow in a steady stream. For soldering 14ga or 12ga solid copper antenna wires together I use a cheap 15 hardware store propane torch throttled to a fairly low flame and a doubled- or tripled- length of fluxcore solder to quickly get enough wetting into the join.
I prefer paste solder because of its ease of use. Remove the soldering iron before you apply too much heat. Strip both wires back by 810 mm.
As copper wiring is used so widely throughout our homes the need to solder it may occasionally arise. Step 3 Plug the soldering guniron into an electrical outlet and allow it to heat up for about three to five minutes. Flux is a caustic paste fluid or powder that prevents the solder joint from corroding from the heat and allows the solder to flow.
Aluminum wire became popular in the 1970s because it conducts electricity well and is less expensive than copper. Try not to touch those surfaces with your fingers. It quickly lost its popularity went it was deemed responsible for a large volume of home electrical fires.
