These materials cannot be reproduced in any formwithout the permission of Hypertherm, Inc.15按照切割參數表選擇合適的消耗件。 使用隨機提供的專用工具安裝消耗件。 切毋用力過度！應用隨機提供的硅脂對消耗件上所有的O型密封圈作涂抹潤滑，切毋過量使用, 僅需極薄一層。 將其擠壓到手指上（只需極少量）然后涂抹到O型密封圈上并作適當摩擦。電極與割嘴應該成套更換。 必要時渦流環也應更換， 一般每更換5-10套

9、電極與割嘴應更換新渦流環。保護帽；保持帽等，一般只在物理性損壞時或切割質量變差時才更換。 Copyright, 2001 Hypertherm, Inc. These materials cannot be reproduced in any formwithout the permission of Hypertherm, Inc.16 保護帽的作用是保護割炬和割嘴不受熔渣飛濺，隔離輻射熱。 保護帽同時又是保護氣或射流水的通道。 Copyright, 2001 Hypertherm, Inc.
