Denhac has two Hakko adjustable temperature soldering stations, one older with a knob to set temperature, one newer digital. There is also a Metcal suitable for finer detail work with it’s own wiki page.
After reading and understanding this page, you are authorized to use them.
For tin/lead solder, 600 ℉ (315 ℃) is a good starting point. For lead free, 700 ℉ (370 ℃). It’s OK to turn it up a bit more, but keep it below 800 ℉. Higher temperatures will degrade the tip quickly. The older iron is ready to use when the red light is no longer solid. The digital one displays actual temperature as it warms up.
Cleaning the tip
The soldering iron stands have sponges. Wipe the iron tip on a wet sponge, there is a bottle of distilled water available. There is also bronze wool that can be used. These are the only two ways tips should be cleaned.
- Don’t touch the metal parts of the iron until cooled sufficiently. They will cause severe burns.
- Safety glasses are advised. You don’t want molten metal in your eye. Solder can splatter as a connection is pulled apart.
- Use the fume extractor fan. Place it near the work, you should be able to see the flux fumes being pulled into it.
- Most of the solder contains lead. Wash your hands after handling, keep the work area clean of solder particles. Denhac stocks lead free solder (AIM REL22) which you may choose if you wish to avoid lead.
- The soldering iron should always be either in the stand or held in your hand. Never set it down elsewhere.
- Turn off the soldering iron when leaving the room or not using for more than 10 minutes. They heat quickly. Turning them off also preserves the tips.
- Keep the area around what you are soldering clean and clutter free. The soldering iron can ignite paper and some other materials.
- Stabilize your work. Helping hands and a stickvise (great for holding small circuit boards) are available.
- The soldering tip is not to be used as a pry bar. Only light pressure is necessary. The tips have a copper core and thin iron plating. Once the iron is cracked or worn through, the copper will begin to dissolve into the solder.

- Be a good neighbor, leave the tip tinned and clean
