Soldering differs from welding in that soldering does not involve melting the work pieces. In brazing, the filler metal melts at a higher temperature, but the work piece metal does not melt. In the past, nearly all solders contained lead, but environmental and health concerns have increasingly dictated use of lead-free solder for electronics and plumbing purposes.+ − <br />+ − + − The current Ace of the {{PAGENAME}} is '''{{#show: {{PAGENAME}} |?Has ace.Has name}}''' ({{#show: {{PAGENAME}} |?Has ace.Has email address}}).<br />+ − __TOC__+ − − == Maker Hub Soldering Irons == − {{#ask: − [[Is soldering iron equipment::True]] − |format=ul − }} − − The Weller irons use a resistive tip to generate heat.

Often, the wires are connected on either end, and the splice is being performed to complete a connection. If one waits until after soldering before adding the heatshrink, it ... uh ... no worky. The heatshrink should be put on first, run down the wire out of the way, and then the wire can be twisted and soldered.

==Troubleshooting==
There are two things in particular that could keep you from successfully soldering: an untinned tip and a loose tip. If the tip is not shiny silver, then place a little solder on the tip and wipe it on the sponge. Some soldering irons allow there tips to be replaced for the sake of having different shapes. If the iron is not heating up and you are using this type of iron, it is possible that the tip is not inserted into the iron fully. To fix this, grab some pliers, grip the shaft and push it in fully.
