Anyyone else having problems with your Kayfun insulators melting?

[Submaniac]

I got 3 Kayfuns from fasttech, 1 ES 3.1 and 2 KFL. The ES I got first. First day of use, melted the insulator. Had to take it to shop to replace all the insulators. Then, I just checked my KFL, and...well...this is what happened with the insulator. Has anyone else had any problems?

Damn, scary lookin' i got mine possibly arriving today and i don't want this to happen, what Ohms you been running at ?

 

[Flt Simulation]

How many ohms is the coil?

How many watts are you feeding the coil?

 

[AdamThomas]

Yeah its got to be lowish ohms and your pumping the watts or something, surely

 

[Submaniac]

It was set at about 0.9 ohms. Straight battery, no VV/VW.

 

[AdamThomas]

So at 0.9 ohm 3.7 Volts, say is like 15 watts.
then a fresh charged would be like, rough guess...18watts ?

 

[Flt Simulation]

I am no expert, but if it was me (using a non-adjustable battery), I would be making the coil to about 1.6 ohms.

A fresh battery will put out about 4.1 volts initially. Feeding your 0.9 ohm coil 4.1v is 18.7 watts (4.6 amps current draw) .... that's alot

A 1.6 ohm coil getting fed 4.1v will = 10.5 watts (2.6 amps current draw) .... much better

^Voltage drop should be considered when figuring out your heat/power level. I use 4.2 to figure out my current needs, but I get an inline meter to figure out the voltage drop under that specific load.

They're more than likely not derlin insulators, which holds up to heat rather well. Look into replacements, may be best to get "authentic replacements."

I also have a fast tech 91 clone going at 0.7ohms..and it has been for a few months now..no issues, but I'm using a horizontal coil.

Edit- I didn't notice your wick is going straight through that vertical... Your coil isn't getting cooled down properly. If you want to use verticals with a bottom airflow atomizer, you need to wrap your wick around the coil.

Suspect is right! Nest that bad boy and your problems will most likely be solved.

I have 3 kayfun lites micro/cotton at 0.69 ohms for months and never had a problem with melting insulators in any of them.

#truth gotta make sure it's cooling right or the heat will keep melting those insulators.

 

[Submaniac]

Thank you for replies everyone. I will go and replace the insulators and redo my wicking technique.

Most likely there is a loose connection somewhere in the base.

It looks your coil may have been in a position to short on the chimney. That burnt mess looks like a short, not just an overheated
insulator.

Push wick up and leave at least .7-1mm gap
Make certain Center pin is Clean and secure.
Double check Ground connection - Clean and conductive.
Clean your Mod 510 connector well.

5 KFL here - ALL FT and no problems.

Yours definitely looks like a localized heat issue (Shorting)
Maybe your Insulator pad was damaged.

that's one burnt looking kayfun my friend and not surprised the plastic melted. non of that black stuff should be there at all so something is definitely causing the heat which in turn melted the insulator. what did it vape like before this happened? oh wait, I just looked again at your pic, what kind of set up is that? wrong set up my friend, looks like your coil is sitting on the deck, screws and everything else. also what is that wick doing? it looks like you have a vertical coil but have wick thru it. I think you need some changes to your set up.

I wasn't aware FT sold Kayfuns...
