Avocado 22 special edition gunking

[Zanzabar78]

Hi there,

I'm having a problem with the avocado 22 special edition and gunking.

The pictures attached are of a fresh coil (26" , 2.5id, 0.6ohm, SS316L) and fresh wick after a quarter tank.

Running at 16 watts , with the two small airholes open front n back. Wicks cut to the top of the glass.

Any ideas on what could be causing the burning/gunking? ive tried differenct juices same result.

Thank you!

Low wattage big coils and dark juice....... equals faster gunking... Fwiw those look broke in to me... when my coils gunk you can't see wraps anymore.

I always thought low wattage = less gunking ? Do you think making it a smaller coil (less wraps) say 4 or 5 wraps would be better?

Actually most gunk form while the coil is heating up and cooling down.... lower watts don't let coil get hot as fast and big coil cool slowly. A faster coil would help... what mod are you using do you have preheat?

Evic vtc mini, yes it has preheat

26awg 316 @ 16watts I'd probably build at around .4 to .5 so 6 to 7 wraps on 2.5mm.

You might try modeling builds on steam-engine.org. ... I shoot for a Heat flux of 170 to 200 and capacity as close to yellow as I can get. I generally vape at 20watts or less. FWIW I JUST ORDERED A SPOOL OF 26 WIRE....first wire other than some clapton I have bought or used heavier than 28 in 2 years of building. Current build in my Avo22 is 10 wraps of 28ss At 1.2ohm running 16 watts with a preheat boost of 150% for 1second. I figure to get equal vape on 26 I would go to .5ohm.

Actually this is the first time I've used 26,was using 28 kanthal and 27 ss316l for the last two years but got 26 for a more stable temperature control (which I haven't used yet in this atomizer), I'll give your advice a shot thank you!

Same reason I ordered it...... TC stability......

My worry is I'll need to run more watts with the 26..... I hate changing batteries....

Hi there just wanted to post an update, your advise worked 100% , MUCH MUCH less gunking when i raised the wattage. Funny that i was doing the exact opposite, lowering wattage thinking it would help, guess you learn something new every day in the vaping world lol

Anyways, thanks again for your help!
