Heating mantle problem

Ihuicatl - 16-3-2018 at 18:25

Hello I'm brand new and have read all of the information I could find about heating mantles with out a variac which isn't very much. Does anyone use one with out a variac? I got one off eBay and it has a temperature knob. Would i still need it? Im really wanting to use it but don't want to burn the house down.

Please let me know what you guys think, any input would be awesome.

You should be fine without a variac for that mantle. I used to have one very similar to that, a cheap Indian mantle with a temp knob. Worked fine without the variac, just didn't have the most accurate temp control.

Gurt thank you for that, it has a three prongs cord as well but I kept reading you have to have a variac or controller. Luckily I'm only using it for essential oils and other herbal stuff so nothing to crazy.

Just keep an eye on it when it's running, I never trust the built in controls a whole lot. Have fun!
