判断可能是气压过大…调节后仍不能喷火…后检查输出气电一体接头胶木老化…拆开后发现因为胶木击穿…造成高频漏于外壳！不能喷火…更换后正常！收工

It may be that the pressure is too big. After adjusting, it still can't fire. After checking the output of gas electric integrated joint bakelite aging... Apart and found that because of bakelite breakdown... Cause high frequency leakage in the shell! Can't spray fire... After the replacement is normal! Call it a day

等离子有高频有空载不打火的故障很多 气压 高频强度不够 漏高频 吸收电路 电路受高频干扰等很多因素都会引起不切割

There are many faults in plasma, such as high frequency, no load and no fire. Many air pressure and high frequency intensity are not enough. Leakage of high-frequency absorption circuit and high-frequency interference will cause non cutting.
