3. When connecting the power supply, we must make sure that the machine has entered the working state (the green indicator light is on and the red indicator light is off). At this time, it means that the fusion splicer enters the automatic control state, and we can proceed to the next step. It should be noted that when the fuser is in the automatic temperature control state, the red and green lights will alternately light up by itself, which means that the fuser is in a controlled state and does not affect the operation.
4. When we are welding, we need to put the pipes and fittings in the machine at the same time, and operate according to the relevant operating standards. When the heating time is reached, we should immediately remove the pipe and pipe fittings from the die head, and insert them straight and evenly to the required depth quickly and without rotation, so that a uniform flange is formed at the joint, and the rebound after insertion should be controlled.
