How to Prime a Coil

You buy a brand new pack of coils for your favourite tank, install the coil and take a drag, expecting a delicious cloud of vapour from your favourite e-liquid.

Instead, you get a strange burnt taste, leading to disappointment and anger.

There are many factors which can cause a burnt coil, but the number one reason is failing to prime your coil correctly.

What is the priming of a coil?

 

A vaporizer coil is the heating element of your vaporizer. Priming your vaporizer coil is simply a matter of making sure that a sufficient amount of e-liquid is soaked into the coil and wick to ensure that it does not burn out when heat is applied.

 

The care and time required for priming usually depends on the resistance of the coil, which is measured in ohms (Ω). In fact, the lower the resistance of the coil, the more cotton / wick there could be. Increased absorbent material leads to a higher potential for dry spots on the cotton and therefore a higher probability of it being burnt.

 

In fact, this is one of the reasons that high resistance coils last much longer than low resistance coils, the others being the smaller area of ​​the coil and the VG: PG ratios of the e-liquid used. . .

 

Which coils need to be primed?

 

Pre-filled pods and cartridges generally do not need to be primed as they have already been exposed to enough e-liquid to ensure the coil and wick are saturated. The exception is when the pre-filled pods are designed to keep the e-liquid separate from the spool until it’s ready to use. When this happens, you should let the capsule sit for a few minutes before using it.

 

All other coils, whether fixed or removable, must be primed. However, the care and time required vary widely.

 

If you use a high resistance coil with a low power battery, the priming process is faster.

 

On the other hand, low resistance coils require more care because, as mentioned above, the increase in cotton and wick increases the chance of burns. This is one of the reasons why we recommend experienced vapers to make better use of high wattage devices and low resistance coils.

How are pods and fixed coil tanks primed?

 

Stationary coil tanks and pods, such as AVP pods, typically have heavy duty coils. With these devices, it is usually sufficient to fill the device and let it sit for about five minutes. It is best to hold your device upright, to ensure that the e-liquid is still in contact with the spool and the coil wick.

 

How do you prime the removable coils?

 

If your coil has a high resistance (for example, greater than 1.2 Ω), you can choose to leave it in the tank and let it enter the coil.

 

You can also remove the coil and prime it by hand. When you remove it, look closely at the coil; you should see holes in it. Run e-liquid through these holes. You will also see a hole at the top of the coil; put some e-liquid in here too, until the wick is full.

 

After adding e-liquid to your tank, you still need to let the coil soak in for a few minutes before using it for the first time.

 

How are low resistance coils prepared?

 

If your coil has a resistance of less than 1 Ω (these are called sub-ohm coils), it is worth taking extra care to prime the coils.

 

The lower the coil resistance and the higher the power levels you use, the more careful you need to be.

 

Make sure to add enough e-liquid through the ports and the top of the coil. Again, once you’ve done that and added your e-liquid, allow the e-liquid to penetrate further into the coil; the lower the resistance of the coil, the longer you should leave it on. For a 0.15 Ω resistance, like the Vaporesso NRG GT coils, I would leave it for ten minutes after filling to be safe.

 

You can also take a few primer puffs. To do this, inhale without pressing the fire button. This helps attract the e-liquid to the coil. However, 1 or 2 puffs should be sufficient, as you don’t want to flood the coil.

 

Once you get the hang of it, you will find priming to be easy and effective.
