Aug 02, 2015 Heating Mantle inter sleeve liner and Variac Anyone used the fiberglass Heating Mantle inter sleeves 500ml, 250w 110vac that Deschem sells to make a DIY heating mandle?. I have searched and seen the various and previous posts. But no one has mentioned using a Variac to power it. I have a 1k, 110vac Variac and it seems the perfect choice.

Aug 20, 2018 Aug 19, 2018. #3. Best use ever. Use it to control the heating power of an electric fry pan. It's always been a pet peeve of mine that the thermostat on an electric fry pan is sooooo imprecise - and that it tries to control temperature instead of heating power. It is impossible to set it to do a simmer on anything.

Variac/Potentiometer heating up - Stack Exchange

Dec 01, 2019 Variacs are variable (auto)transformers, not potentiometers. The limitation on the variac current is the output current. If it is rated at 8A you can draw 8A at 1V (8VA) or 8A at 200V (1600VA). You can expect them to get warm during operation due to losses, like any transformer. Probably good quality ones will get less warm than less good ones ...
