Design
The first nice thing is that everything is balanced very well, it looks like it would stress your arm and wrist out but that is not the case at all, it is very light.
The second thing that makes this tool very nice is the vacuum pump itself, it uses a double diaphragm pump so there is very good suction with no pulse and constant vacuum. It also appears that a ball bearing was used to connect the pump connecting rod to the shaft of the motor which will last much longer than sleeve-style bearings, though this is not confirmed about this gun using a ball bearing.
The third thing is that the tips seem to last a long time unlike some of the other cheaper soldering tools we have used. The replacement tips are not too expensive and you can get different sizes as well which is another great plus.
The fourth thing that makes this tool very nice is the fact that you have access to every part of this gun which will make maintenance very easy, the back housing is removable to expose the diaphragm pumps and connecting rod if there is ever a need to inspect or repair the pump.
As it turns out these units have a typical design flaw – because the pump is so far away from the desoldering iron tip the suction is somewhat weak. Keep in mind that air is flexible so the longer the tube the more pressure is lost along the way.
The Hakko 808 Kit comes with a carry-on case and a few spare parts. What is missing is a holder, which you can buy separately, however, the tool will lay on its side on the table without touching the surface so that will suffice if you don’t have a holder. Another feature that is missing is an on/off switch, unplugging this from a power outlet is not convenient especially if you have to crawl under the table with a hot tool on the table.
Performance
The heating element is powerful enough to quickly heat up and liquefies solder joints – even if they’re located in a large copper ground plane (you can speed things along by first melting in some 63/37 solder).
The vacuum pump is best described as a “V Twin”, and it produces a strong instantaneous vacuum that completely clears the solder joint on the first effort.
There is no comparison to using low-cost suction devices. It has been so reliable and effective in removing parts without damage to the part of the board.

- Next, turn on the power switch and preheat the gun for about 10-15 seconds;
- Then, press the trigger to activate a strong vacuum suction and quickly apply it to the solder joint you want to remove;
- Once all of the solders has been removed, release the trigger and allow the gun to cool before storing it away;
In terms of performance, this Hakko desoldering gun does an excellent job of quickly removing solder without damaging components or leaving behind any residue. It also has a comfortable grip and easy-to-use controls, making it a pleasure to work with.
Are desoldering pumps reusable?
Desoldering pumps come in a wide range of styles, from handheld pumps to electronic, heated guns that require no iron to use. They are great for reworking small parts and getting solder out of pin holes. Removed components can be reused [3].
Unlike traditional desoldering pumps, which can only be used once before needing to be replaced, the Hakko 808 can be used over and over again. This not only saves money in the long run, but also reduces waste and is more environmentally friendly. Additionally, the design of the Hakko 808 allows for easy cleaning and maintenance.
What temperature should I desolder at?
The Hakko 808 desoldering gun allows users to adjust the temperature between 350-480 degrees Fahrenheit. It is recommended to use a lower temperature for delicate components and a higher temperature for larger joints.
How does a solder wick work?
To use a solder wick, simply place the end of the wick over the solder you want to remove and then place your heated solder tip over it. The braid heats up and encourages the solder to “wick” into it. When it starts to work, you will actually be able to see the solder being pulled up into the solder wick [4].
What shouldn’t you touch in soldering?
Remember to never touch the hot element or tip. Touch the soldering iron onto the joint to be made. Make sure it touches both the component lead and the track. Wait for the solder to melt and flow onto the joint [5].
Why use a desoldering gun?
A desoldering gun, like the Hakko 808, can quickly remove excess or faulty solder from joints. This is especially useful when fixing mistakes or replacing components. The Hakko 808 features adjustable power and temperature settings as well as an easy-to-use trigger mechanism.
How does the Hakko 808 perform?
The Hakko 808 performs well in most situations, with its adjustable power and temperature settings allowing it to handle a variety of jobs. However, some users have reported issues with reliability over time and inconsistent suction power.
How do you remove solder without a wick or pump?
Heat the solder with the iron, then with the iron still on press the silicone end over the pad and iron and fire it, works so well, and will remove even small amounts of solder, and a low-power iron helps avoid taking the pad off the board.
The Hakko 808 Desoldering Gun is a tool that can easily and quickly remove solder from circuit boards. It features adjustable temperature control, an easy-to-squeeze trigger mechanism, and a replaceable silicone nozzle.
In our experience using the Hakko 808, we have found it to be efficient and reliable in removing solder. The adjustable temperature control allows me to use the gun on a variety of components without worrying about damage. The trigger mechanism also provides precise control over the release of hot air, making it easier to target specific areas for desoldering.
What two methods are commonly used to desolder?
One is with a desoldering iron. It is a regular soldering iron but it has a bulb attached so that when you melt the solder, you can squeeze the bulb and then release it quickly and it will suck up the melted solder.
The other method is a roll of flat braided wire that you put down on top of the solder joint and then heat with your soldering iron and the solder will wick up into the braid. We’ve done it a third way by holding the item in one hand, heating the joint with the iron, and then giving the item a quick flick of the wrist and the solder goes on the floor. Not good if you have rugs [6].
How do you remove old solder that won’t melt?
One option is to use a desoldering braid. It is a small roll of flat, braided wire that you heat up with the soldering iron and place on top of the solder joint. The heat from the iron will cause the solder to wick up into the braid, removing it from the joint.
Another option is to use a desoldering pump, also known as a solder sucker. This tool has a plunger mechanism that sucks up melted solder when activated after heating up the joint with a soldering iron.
If these methods do not work, you can try using chemical flux or a specialized adhesive to dissolve the stubborn solder before removing it with one of the aforementioned tools. It is important
How often should you tin a soldering iron?
You want to keep your tip tinned at all times, from the first time you use it until you discard it. When you tin a tip, you cover it with a thin layer of solder.
When you unbox a brand-new soldering iron, the first thing you need to do is to tin the iron plating on the tip to help protect it from oxidation. Keep in mind you should lower the temperature down to about 500°F for this process. It is not uncommon for a new tip to be oxidized out of the box [7].
Can you use flux to remove solder?
Flux is used to clean the metal surface, promoting better solder flow and improving the quality of your joints. It can also help remove oxides from previous soldering jobs, but it does not necessarily have the ability to physically remove excess solder on its own.
In some cases, using flux in conjunction with a desoldering tool or wick may be helpful in removing excess solder. However, for best results, a dedicated desoldering tool such as the Hakko 808 is recommended.
Why should you use a desoldering gun instead of a regular soldering iron?
Desoldering guns are specifically designed for removing solder, often consisting of a vacuum pump that helps suck up melted solder. This makes the desoldering process faster and more efficient than using a regular soldering iron.
In comparison, a regular soldering iron may struggle to properly remove excess solder without causing damage to sensitive components or leaving behind residue.
