A word of safety to all mechanical users

[Stray Black Cat]

This thread was a fun read. Several people asked the right question but never got an answer. The Mech users demonstration themselves just how dangerous mechs can be even with veteran users that seem to have forgotten the rule "Know your build". There is nothing wrong with the iClear 30 and they are not prone to shorting. The issue is using them correctly in a regulated PV. 2.4ohms IS NOT 2.4ohms when it comes to safely checking a build. You need to know the gauge and composition of the coil. The iClear performs exactly as designed up to the maximum power on same manufacturer variable devices. However the ~32 gauge Kanthal coil of an iClear is not capable of handling the in-rush from the unregulated 30 amp Mech. This turns the coil to molten beads. If you watch a rebuilds of the coils that are posted on YouTube, you will see a thin gap between the positive hollow pin and the negative outer tube. This is separated by a soft insulator at the bottom. This leaves a narrow channel above the insulator that the beads fall into and dead short. Put an iClear on an unregulated mod and your lucky if it does not short. The different guages of wire are more than just thickness, They're current carrying capacities. In short 2.4ohms of 32 gauge wire cannot handle the same current as 2.4ohms of 24 gauge wire. KNOW YOUR BUILD....

It doesn't work that way Stray Black Cat.

Mechanical mods fire at the voltage the battery has. Here's a online Ohm's law calculator. With a full charge that will be 4.2V. 4.2V at 2.4 ohms means the battery will see a 1.75 amp draw and the iClear will produce 7.35 watts. This doesn't take into account voltage drop under load, so there will be slightly less than 7.35 watts produced.

This will not hurt iClear coils

The only time a battery will dump it's full amperage is with a direct connection between the anodes. once you put a coil in that line, it changes from being a line to a load, and anyone who knows even rudimentary electrical theory knows that a load only draws the current (amps) that it needs. If mechs worked the way you stated, then EVERY build would short out at the coil.....know your electricity

My error was carelessly assuming ~32 gauge coil on an iClear 30 without tearing one down and putting a micrometer to it. The following Kanthal A-1 gauges and lengths all equal 2.4ohms: 32gauge@2.198", 30gauge@3.445", 28gauge@5.465", 26gauge@8.701", and 24gauge@13.913". 24gauge being 2 1/2 times the diameter of 32gauge. You will not convince me that as these gauges share the same characteristics and failure rates. The issue falls more under physics then electric theory. I have yet to find any specifics on current limits on the various kanthal gauges but I know enough not to expect 1 foot of 32Kanthal ~13ohms to replace a house furnace 13ohm coil. I still stand by my answer of capacity.

I think there is a design flaw in certain nemesis clones that can leave you setting the mod down with the lock ring engauged and there still be a short across the battery, I have toasted 3 batteries due to this. Unfortunately I haven't been able to track it to a particular nemesi as it happened so fast the nemesis got mixed in with the others. I believe it may be the short throw spring I bought from one of the vendors.

watch this.

After screwing with gauge and current calculations, I determined I'm over complicating the matter. Stepping back with a fresh look over the information, I should have seen it immediately. If I am correct in assuming, this Mod has an adjustable screw in the 510. If this is too high, it makes no difference on a rebuild-able. But on an IClear 30, this would crush the soft insulator and short the positive bullet pin with the negative tube when attaching the iClear. This is a risk on any adjustable 510, regulated or not. Vaping makes you see thing clearer.

^that's better.
