Material Introduction

The main body is constructed from high-purity alumina ceramic, which delivers excellent high-temperature resistance, stable electrical insulation and low thermal expansion. The threaded insert is precision stainless steel for accurate thread matching and good coaxiality. Built-in rubber O-ring provides reliable sealing to block slag, dust and auxiliary gas leakage during laser cutting.

Instructions

1. Check the ceramic surface for cracks, chipping or damage before installation. Do not install defective insulators.
2. Clean the thread and contact mating surfaces to remove dust, cutting slag and oil contamination.
3. Hand-tighten the insulator gently onto the laser cutting head. Excessive torque will crack the ceramic body.
4. After assembly, test the height sensing signal and run a trial cut before formal production.
5. Replace the insulator immediately if sensing failure, burning marks or ceramic breakage occurs.
6. Store in a dry, dust-free area and avoid impact or heavy squeezing.
