Tips for Mounting an Induction Heating Coil

When mounting an induction heating coil, be aware of the following steps and tips:

  1. Turn off cooling water
  2. Turn off the main switch
  3. Place a bucket under the inductor to capture leaking cooling water
  4. Loosen the nuts (6) on the connector jaws (2) so as to release the thrust pieces (5)
  5. Pull the inductor (1) towards the top and remove
  6. Clean both contact surfaces (3) with a Scotch-Brite™ pad
  7. Check both O-rings (4) for damage and replace them if necessary
  8. Check both contact surfaces (3) for damage
  9. Insert the new coil. Ensure the coil and the coaxial transformers have a tight fit

Caution! Be sure to use only brass washers and nuts.

Use the following torques when tightening the nuts:

  • M6 nuts = 9 Nm
  • M8 nuts = 13 Nm
  • M10 nuts = 19 Nm

Please also be mindful of the following:

  • Over-tightening can result in thread stripping on the nuts (6)
  • Under-tightening can cause :
    • Arcing between the coil and coax contact surfaces (3), which can lead to surface pitting
    • Current running through the stud to the clamp, which can melt the stud
