    How to fill up a Sigma EVOD vape tank

    Sometimes most vapers choose to refill their tanks on the own, and the Sigma EVOD is not any different from all the other refillable vape pens. To fill up your vape pen, you will need to take the tank off the battery and remove the best tankIf you have some liquid left in the device.

    Then it is advisable to carry out this operation with your device upside down to ensure you do not mess up by spilling the remaining liquid inside. Once the tank's base is off, you can look into the bottom of the tank, and there you will see an airway. This is a long cylindrical tube that is connected to the mouthpiece.

    You will now have to get your dropper or syringe, insert the end into the airway side, and squeeze carefully to release the liquid into the tank. You have to ensure that this operation takes place on the airway side to prevent it from pressing into the mouthpiece. 

    Ensure that you fill up to three quarters, and you can check this by looking at the side windows on the side.  When you are done, make sure that you have tightened the atomizer onto the base and re-attach your tank's bottom. This process should be done with the tank upside down to avoid spillages.

    How to charge your Sigma EVOD battery

    At this moment, you probably know a few things about the Sigma EVOD vape pen, and there is a time that you need to re-charge your battery to keep you in action. And to do so, you will need to do a few things.

    The first thing to do is take out the whole vape tank from the battery where the 510 threading is placed. You will proceed to take a cotton swab and clean the top of your battery where the 510 connection is. This process ensures that no vape juice has leaked down into the storm to cause damage.

    Once everything is set, you will now screw the charger into the 510 threading and check to ensure that you do not over-tighten the charger to keep the battery safe. 

    Changing your Sigma EVOD vape pen atomizer

    After a few days of using the vape pen, you will realize that the vapor production is not similar to what you experienced when you first bought the vape pen. When this happens, it means that you need a change of atomizers. The longevity of atomizers is measured by how you inhale, how much voltage you are running on, and the kind of compound.

    You will start by removing the tank from the battery, and once the tank is separate from the pen, go ahead and remove the tank's base to show the atomizer. Grip on the atomizer and start unscrewing in a counter-clockwise direction. Do this until it completely detaches from the battery.

    Before you place in a new atomizer, you have to prime it. To prime your atomizer, drip 3 to 5 drops of liquid into the top of the atomizer and let it soak. You can also soak the wick itself to make the saturation process quicker. 

    Once the priming process is over, you can now screw in your atomizer in a clockwise direction on the 510 threading.
