被切割工件的表面和里面,不能有易燃、易爆的附着物和对人体有危害的

化学物品。

 

 

安装和维修人员必须持有国家认可的电工操作证。

 

 

切割操作人员必须认真阅读本说明书,熟悉操作方法。

 

 

当切割机放置在倾斜的平面时,应注意防止其倾倒。

 

 

气泵需要定期保养,及时更换消音器,使用切割前可切换到试气功能排除

枪体内的水分。

 

 

本产品按照工业标准设计,可能会产生电磁干扰,使用时应作好充分的预

防措施。电磁场对健康的影响未经证实和查明,不排除对身体有负面影响。

磁场会影响心脏起搏器,起搏器使用者应远离。

 

 

本切割机静外特性为降特性,其额定负载持续率为

60

%,是指在

10

分钟工

作周期内,切割机在额定切割电流状态下工作

6

分钟,休息

4

分钟。当切

割超过额定负载持续率使用时,切割机内部温度上升将超过设定温度,为

了避免切割机性能恶化、甚至烧毁切割机的危险,本系列切割机设置有热

保护功能,当切割机内部温度上升超过设定温度时,热保护动作,切割机

面板上过热指示灯亮,此时切割机无法切割,必须等切割机内部温度下降

到低于设定温度时,切割机面板上过热指示灯熄灭,切割机才能恢复正常,

方可继续切割。

 

 

本切割机供货状态为纸箱包装,重量轻,没有提升装置,用户可以采用人

工或升降叉车将其搬运到位,然后拆箱。
