Wick and coil break in time

[Jonibrasco]

I am on my 3rd wick and coil and everything has a metallic soup can taste. I have vaped each set about 10 mil of juice... its a soup can taste with high th and muted flavor. Its not a hot spot yuck taste. The flavor is there but its overpowered with a metal tatse. I am using a natural and rsst, 400 mesh 28g kanthal with 3-4 wraps. Using pulse to get even glow wiyh no hot spots that i can see. The coil is just loose enough to allow the wick to slide with pressure. This is my first rba and so far my boge cartos blow this away.. what am i doing wrong? It does glow from top/bottom to the middle not middle out

Also it seems to fire ok.. its a pretty constant hiss but after about 4 seconds or so it starts spitting to the point that i can feel the spatter if the top cap is off.

I don't have any experience with tank style RBAs, but until someone comes along that does I'm wondering if a higher ohm coil might work better for now. I think a 3/4 wrap of 28ga is a sub-ohm coil and the super low res is harder to set-up than something like 1.2 or higher for beginners.

I found that using mesh wicks. I went back to silica.

it usually takes a whole tank of juice but the metal taste is most likely to loose of a coil you want real good surface to surface (wire to wick) its more trouble sometimes for hot spots but worth it i find it to taste better and the metal taste is a wick getting to hot good surface to surface helps keep the coil cool from the juice dont give up when it works its awesome

tight wrap coils never loose on ss
you can spread from the center of the ss with a wood toothpick carefully
it will oxidize itself after a couple of firings if all things are done
what I just said
when the coil is loose it spits
it can be the bottom/top coil leg is to far from post
or wick is too loose
so bottom the bottom legs on base closer to the wick
move top legs closer to top post

try dry burning it, and see if the coils glow evenly. if not, that's your problem right there. it's most likely either that or you're not wicking enough. heating too hot in an area, or not having enough juice will give you that hot metal taste

You might not have a big enough airhole. If you're not getting enough air it will throw the taste off and throat hit will be really strong.

I already drilled out the air hole and when pulsing it the coils were somewhat even glowing but not perfect. Its not a burnt taste. It tastes like vaping with a penny in my mouth

I think what flow prof said was right. Your coils are either too hot (too high a wattage) or your mesh isn't wicking fast enough.

If you see that ur coils still glow red while the juices burns that's where it's coming from. I used to have this problem a lot when I first went into rbas.

Also try reoxidizing ur wick and flaming ur coils/wire.

Only time i see red is after holding fire button for 10 seconds

Is it possible that kanthal just taste like metal to me? What is the nichrome equivalent to 28g kanthal

I doubt it. 29 gage nichrome, which may be difficult to find.

What is your resistance and voltage? Burnt juice sometimes has a metallic or gasoline type taste to me. Are you sure your airflow over the coil is good?

Ok made a new wick and coil. This time i oxidized it with a torch. Torched the wire also. Wrappedbthe wick tight out of the rba. .9ohms cant see any hot spots. It still tastes like i have a penny in my mouth. Not as bad as it did before, but it is still there

I think i figured it out.. hot spots that werent red... i noticed 2 places that bubbled the instant i fired... adjusted the 2 spots and almost no metal taste... these rba's are sneaky .......s

I usually get a metal taste if my wick isn't dense enough. I think it's because it's not wicking juice fast enough and you end up heating the wick up too much. Too small of an airhole gives me the metal taste too. I think that follows the same reasoning of the wick getting too hot.
