Pyro 4 issue

[Silverback01]

Hi All,

been using the Vandy Vape Pyro 4 for a couple of weeks and aside from having fun trying to get it to wick correctly, I notice the top cap getting very VERY hot. Originally used the supplied coils at the correct leg length .21 ohms and vaping at around 45w, after a couple of minutes you almost couldn't touch the cap due to the heat.
Swithed to a single coil setup at .4ohms, again running at similar wattage and still gets unbeleivably hot. Its actually started to melt the underside of the drip tip !
Anyone else had similar issues or am I just over vaping it ?

Cheers

Not got one of these. I gave up on rdta’s ages ago. I reckon cos the coils are at the top you are going to get a lot of heat transfer, just like a dripper. You hammer it will get hot. I have had loads of hot lips hammering drippers. And rtda’s.

Hot lips and burnt tongue !

Possibly. Is it vaping ok, wicked and coiled right, and do you hammer it.

It's a bit hit and miss with the wicking, vapes great when I get "just the right amount of cotton", but this has been trial and error so far - less is more ! Coil height is fine - well below the base of the drip tip and top of he cap.
Bit of spit back when coil(s) start to gunk up and yes I do "hammer it", but no more than my previous Forz RDA which coped just fine.

It's my first rdTa so perhaps its just a learning curve ?

How much have you shut down the airflow, if at all? And are the coils positioned so they are close together over the central 'shower head' part of the airflow? If you have them positioned between the central 'shower head' that provides most of the airflow and the smaller outer holes airflow with a large gap between them it looks to me that most of the air can pass between the coils without actually hitting them. Try positioning them centrally with a small gap between them (if you haven't already) and see if this works.

I have the airflow pretty much wide open (say 90%) and have tried the 2 coil setup both close to the centre and close to the sides (centre was better as you suggested), now using a larger single coil which is centrally positioned, still same excessive heat on the top cap though.

Its probably just me giving it too much of a beating as no one else seems to have mentioned heat problems ?
