现场安全资料实例（336）施工机械操作规程牌45

施工机械操作规程牌45

对焊机操作规程

1．电焊机的使用应执行JGJ 33—2001第12.1节和第12.4节的规定。

2．对焊机应安置在室内，并应有可靠的接地或接零。当多台对焊机并列安装时，相互间距不得小于3m，应分别接在不同相位的电网上，并应分别有各自的刀型开关。导线的截面不应小于表1的规定。

表1 导线截面

对焊机的额定功率（kVA）	25	50	75	100	150	200	500
一次电压为220V时导线截面（mm²）	10	25	35	45	—	—	—
一次电压为380V时导线截面（mm²）	6	16	25	35	50	70	150

3．焊接前，应检查并确认对焊机的压力机构灵活，夹具牢固，气压、液压系统无泄露，一切正常后，方可施焊。

4．焊接前，应根据所焊接钢筋截面，调整二次电压，不得焊接超过对焊机规定直径的钢筋。

5．断路器的接触点、电极应定期光磨，二次电路全部连接螺栓应定期紧固。冷却水温度不得超过40℃；排水量应根据温度调节。

6．焊接较长钢筋时，应设置托架，配合搬运钢筋的操作人员，在焊接时应防止火花烫伤。

7．闪光区应设挡板，与焊接无关的人员不得入内。

8．冬季施焊时，室内温度不应低于8℃。作业后，应放尽机内冷却水。
