How to Extend Induction Heating Coil Life to 200+ Uses

Alicia Hawkins - Friday, May 18, 2018

Here are some tips for how to maximize coil life for your Mini-Ductor® model and the U-555 Mini-Ductor attachment for the Pro-Max and Max models of the Inductor Series®:

  • To avoid overheating and damaging your coils, use the device for two minutes on, two minutes off – on Mini-Ductor models, the inverter will automatically shut off if it overheats
  • Keep space between your coil and the bolt, fastener, bearing, etc. and your coil – the part doesn't need to get red hot; just heat for 5-10 seconds and, if it's difficult to get off, heat for another 5 seconds
  • When using the 41" or 96" Bearing Buddy: use a plumber's mat to avoid abrasion and overheating

Mini-Ductor Coil Replacement

When to replace your coils:

  • They start to turn brown
  • The fabric over the coils begins to tear

If you own an Inductor Series Glass Blaster or Concentrator attachment, remember to replace your thermal tape once it starts turning brown.
