Inductive heating is used to efficiently solder hard metal, and single- and multicrystalline diamond tips on tools, cutters, ends, inserts and dressers. CEIA devices have a constant power supply and extremely accurate temperature control, which limit heating to the soldering area only, thus safeguarding the technical features of the cutting tip. It avoids overheating the brazing alloy, extends the life of the tool and improves the operator's working conditions. Use of the most up-to-date electronic technology and advanced components guarantees higher than 90% power output, allowing the complete use of the absorbed power and contributing to reduce operating costs.
