1。准备工作结束后，打开操作开关，仔细调整工作电流并开始焊接。2。出于任何原因，当电焊接机停止在中间工作时，计时器将记录当前通过的时间。按下第一个键重置并重新打开）3. Make preparations, connect the wires—turn on the power switch—set the voltage and time—turn on the operation switch—start the timer—adjust the current to the set value (slowly adjust) and start welding—when the set time is reached, the buzzer sound Automatically cut off the power when the device sounds-turn off the operation switch to OFF, and the current knob returns to zero-take off the connecting wire clip-cool down according to the指定的时间检查 - 工作的结尾。4。当电压太高或电流太高时，焊机将自动关闭电源。因此，在判断焊机是否在正常数据下工作时，只需关闭，然后打开电源以切断设备以将系统恢复到正常状态。 https://www.chbuttfusionweldingmachine.com/
