Hi there. I just bought Therion 75C. Then i setting TC Mode with escribe new version, i do same procedure like how to setting TC Mode in my therion 166. Choose material, setting up ohm, temperature limit, preheat punch, time and power. Then i upload my setting to the mod. Its firing normal, and when liquid dry, then i try to firing again, but why the temperature protect doesn't appear?. It just keep firing ( yes the power is decreased automatically ) then make my cotton burned. Please help.
