Sorry to hijack this thread. But I really need some advice but do not wish to open another thread.
I have been building titanium coils (spaced and contact coils) for the past 3 weeks on tfv4 without success. Running the tank with ipv d2 or evic vt mini.
Every time I build a new coil, the first 1/2 to full tank would feel good
vaping. But the firing would weaken on the next refill. I will have to increase the temp in order to improve the firing. The flavour also degraded. It would weaken until it cannot be fired. New coil cannot last more than 1 day.
I am using 24awg ti gr1 wire with 9-10 wraps and Diameter 3mm. Resistance is at 0.28 to 0.33ohms. New coil firing at 420F and 50w was good. Subsequently has to increase the temp as the firing weaken. I would wrap a coil and set up the tank with juice and then sit the tank for 5 mins before locking the resistance.
Anyone has any idea where I did wrong?The coil just couldn't last more than a day.
