How to get rid of solder fumes

The fumes that are emitted while soldering is not as safe as you think. You might not realise it but these fumes are not something you should be breathing in as they are toxic and can lead to irritation and even asthma if inhaled regularly. What is the solution to this you may ask? Don’t worry, we’ve got you covered. Just follow the simple steps given below to direct all the harsh soldering fumes out of your house so that you can solder without any worries.

 

Products needed for this DIY project:

  1. Two 120-millimetre computer fans
  2. DC jack with wires
  3. Flexible ducting
  4. Velcro
  5. Cardboard shoe box
  6. Cardboard sheets

 

Gather all these products from any local store to get started with our DIY project!

 

Step 1:

The first step for making the structure to protect you from soldering fumes is to solder the wires of the 120-millimetre computer fans in parallel using a soldering iron and extend them out to the DC jack.

Step 2:

Next, draw and cut two 115-millimetre holes on the side of the cardboard shoe box. The 120-millimetre computer fans will be fitted into these holes.

Step 3:

Mount the fans to the inside of these holes using the screws that came with it. secure them properly so that they don’t fall out at a later stage.

Step 4:

Make a small hole for the DC jack at the back of the box. Insert the DC jack into the hole that you just made and use some glue to carefully stick it in place without messing up any of the wires.

Step 5:

Now you need to cut out a large square on the side of the box and find a cardboard sheet to fit over it.

Step 6:

Bring out your flexible ducting and trace out a circle the size of the hole of the flexible ducting on the cardboard. Make a smaller circle just inside this previous circle so that there is a space of 1 centimetre between the two circles. Using a knife or a pair of sharp scissors, carefully cut out the small inner circle.

Step 7:

Once you are done with the previous step, use a stapler to attach the cardboard sheet that you just cut and the flexible ducting. Make sure that the circle that you just cut on the cardboard sheet aligns with the opening hole of the flexible ducting.

Step 8:

Add some Velcro strips to the edges of the square that you cut out from the cardboard box and the cardboard cut-out with the flexile ducting attached to it and stick them in place.

Step 9:

Seal all the edges of the box using some duct tape. Not only will this help with preventing any of the extracted soldering fumes from escaping but it will also help to make our structure stronger so don’t be shy to use as much duct tape as you want.

Step 10:

The last step is to add a shroud around the fans to direct the air flow. For this simply stick two pieces of cardboard to the sides of the cardboard box that has the fans and put another cardboard piece over it. These can be folded in when not in use so that it does not occupy too much of space.

The structure is now complete. When you are soldering anything simply do it next to the structure that you have just created and put the flexible ducting out of your window to direct all the harsh fumes out of your house. Now you can solder away and be safe!
