Read these guides to improve your knowledge in soldering electronics:


What is the duty cycle?

Because the device’s duty cycle is only a few minutes at a time, it must be cooled down after each usage.

What Weller tip should I use?

The manufacturer recommends using 7250W as a standard Weller tip for this particular device. Alternatively, you may use 6150 as a cutting tip and 6160 as a smoothing tip.

What wattage is it?

This soldering gun produces either 200 or 300 watts of power, depending on the trigger option.

What temperature does this soldering gun reach?

It quickly heats up to 900F in just 6 seconds. It may reach a maximum temperature of 1100F.

How do you use this soldering gun?

After proper cleaning and thinning the tip of your Weller soldering gun, you should do the following steps:

  • The first step is to determine the correct temperature for your project. The temperature you use depends on the materials you’re joining and the type of solder you’re using. The best temperature to use is the one that’s as low as possible while still accomplishing the task. In other words, if the required temperature to do the job is 370 degrees
  • Fahrenheit or above, set it to exactly 370F. This will assist your equipment last longer and avoid causing any electronic components damage;
  • Turn off the iron if it’s still hot. When it’s time to join two pieces of metal together, grab the iron by the handle with one hand and a piece of solder with the other. To heat up the metals, hold the hot tool to them for around a second. You don’t want to melt the molten solder;
  • Then, using the soldering iron, touch the heated components to the solder. The solder will flow into any gaps it needs to fill as it melts. Continue to add solder until a sufficient amount is melted. You don’t want too much or too little solder in this situation, so you’ll have to figure out how much is ideal for each project on your own. This stage may take anything from a few seconds to a couple of minutes, depending on the complexity of the job at hand;
  • Allow the solder to cool. It won’t take long for it to cool on its own. It shouldn’t take more than a few seconds longer;
  • Examine the soldering junction for quality. A good connection will have a smooth, uniform, and brilliant appearance. Check to see whether there are any gaps between the components or globs of excess solder in the connections;

How to clean Weller soldering guns?

The best way to clean your Weller soldering gun is by using the help of a de-soldering pump [1].

After removing any excess solder, you should immediately turn off and unplug your soldering iron. Then, remove the tip from the device by pressing down on it until you hear an audible click. Put that into its separate storage box or tube for safekeeping. Now reach for your de-solder tool’s plunger and place it against anything but the opening in which hot air will escape through when you squeeze with all of your might!

Begin pumping away at this area while shaking up and down around three times per second (for 30 seconds). Remove each piece after finishing one before adding more pieces back in throughout this process.

You can also try using a desoldering wick [2], which is even easier to use.

Start by removing any excess solder from the tip of your Weller soldering gun and then turn it off and unplug it before moving on to the next step: replacing its tip if necessary.

Then reattach everything back together once you’re done with all steps in this process (and plugging it back into an outlet). Cut out about one inch of each end of some de-soldering wick, leaving the only metal exposed at either side for this task.

Place that metallic surface up against whatever opening will allow hot air through when squeezed – not necessarily directly touching what you plan on cleaning! Now press down hard on both ends so they’re held tightly against the components in question, and then give it a few seconds to do so.

The only drawback of using a wick is that you have to be extremely careful when cleaning up any excess solder because they can’t withstand as much heat as other tools used for this particular task. If anything gets too hot, it will melt easily from its tip or even into those metal pieces at either end! You’ll have to remove them immediately if that happens by cutting off more of each piece with your de-soldering wick set – just remember not to expose any wire underneath!
