Evic VTC Mini Stainless Steel issue

[workman70]

So, I've been exclusively TC for the last year or so. I've been mainly using Ni200 with Kanger Subtanks pre-built coils. I picked up some of their newer Stainless steel coils and moved the Evic VTC to SS mode.

I typically run in TC mode between 450-500, depending on juice. In stainless steel, I had to move it down to 350 or its just way too hot. Has anyone else experienced this? I don't think it's the coil, as I've tried a few with the same heat delta.

not really an issue thats just the way ss wires behave,
generally hotter than ti or ni

( i am assuming you are using the right mode or with the right tcr value the very least)

Supposedly the SS mode is calibrated correctly. I guess my issue is this...450* is 450* regardless of the medium used. So if 350* in SS is 450* in Ni200....then it truly isn't temp control. I know, it's temp regulated not controlled. But there shouldn't be variation in categorizing heat.

While I normally test home built coils - I suppose store bought ones can be tested to.

Empty/rinse your tank & coil well with tap water. Soak your coil for a few minutes in plain water and fill your tank with water - then reassemble with a water wet coil and water filled tank.

Before remounting it on your VTC-Mini, set your watts to something low like 10-20W and you can leave your temperature at whatever you had (as long as it is over 300F).

Remount the tank and while watching the screen fire your mod. A the displayed temperature of a properly calibrated wire/TCR combination is 212F. Your display may 'hover' by, near or close to 212F if the wire you are using is a match to the TCR setting. (note: if you fire for longer than 10-15 seconds the temperature will rise while the wick is getting dry)

If the TCR is to high the wire will be hotter (212F) than what is displayed (displayed temperature is < 212F) and the TCR needs to be reduced. If the TCR is to low, the displayed temperature will be above 212F and the TCR needs to be raised.

Once you think you have it dialed in fairly well then you can drain/dry the tank and air dry (don't dry fire otherwise you may damage your cotton wick) your coil, refill with juice and enjoy.
