When to Replace Mini-Ductor Induction Heating Coils

While mechanics and body shop owners love their Mini-Ductor® Venom and Mini-Ductor II, the effectiveness of these portable induction heaters – and safety – are contingent on the state of the coils used with them. Many don't realize that these coils need to be replaced over time, but how do you know when to do so and where can you go to buy them?

This blog answers those questions.

Coil Replacement

Mini-Ductor coils are manufactured in a variety of lengths and sizes to fit inaccessible areas. Standard coils need to be replaced anytime that the metal underneath the fabric coating becomes exposed – otherwise, you can get sparking and the possibility for fire, which defeats the purpose of using induction heating in the first place vs. a torch. Another sign that coils need to be replaced is if the fabric becomes noticeably brown. Each coil will last for several hundred uses or more subject to use. Click here for proper coil usage.

Bearing Buddy coils are much longer (41" to 96") than standard coils. They need replacing when metal becomes exposed and/or turns brownish like standard coils, but also when they become brittle since they are made of finely twisted copper.
