Use and abuse are often the culprits to blame for damaged induction heating coils. Coils get dropped, banged up and dirty. According to Mark Kozlowski, eldec LLC's Engineering & Service Manager, a little TLC can go a long way to helping extend the life of this expensive type of tooling.
- Protect your inductors. They can be fragile. Put them away when not in use. Don't leave them near the edge of a workspace where they could be knocked off or dropped. This is especially true for coils that are used in hand held operations, such as brazing copper. Dropped coils not only might break, but they could also stop functioning or lose their form.
- Use clean water for your operation. Heating with a low water flow or dirty water will shorten the life span of the coil.
- Clean your coils after use. Build up of foreign materials can cause a short across the leads and damage the coil. The best way to clean a coil is to wipe the coil off with a clean towel or rag and blow the particles off with compressed air. A Scotch-Brite™ pad can be used to clean the coil foot electrical connection point.
- Inspect the Teflon® insulator between the copper leads for damage prior to use to avoid shorts.
- Use a coax saver, which is an adapter that acts as a short extension between the coax transformer and the induction coil. If this type of adapter is used and the coil is mistakenly installed too loosely or too tightly, the damage occurs to the coax saver (which is relatively inexpensive) rather than the expensive coil or coax transformer.
- Install your coils properly. Installing induction coils correctly can prevent costly down time and repairs.
Follow these tips and your inductors will last longer. When accidents happen or your coils wear out, give eldec a call. We can repair or replace your coils quickly, preventing costly down time.
