Why The Device Always Show “Device Too Hot” When You Press The Fire Button?

A lot of new vapers have a problem, that is why the device always show “Device too hot” when pressing the fire button. No matter what device, please let it cool down for a while when you use a long time. The higher wattage is, the bigger current will be, then the higher temperature will be, so it will cause more heat.

You can try to use TCR mode and set the TCR value according to your coil’s material. The TCR value range of Nickel is 600-700. The TCR value range of NiFe is 300-400. The TCR value range of Titanium is 300-400. The TCR value range of SS(303, 304, 316, 317) is 600-700. Our default setting is SS316, TCR value is 120. If the value is not correct, the device will detect itself and give a wrong judgment and output.
