Step 7: radiator fan is closed, if first waits for that the end of continued access consumptive material and second waits for that the non-welding of the head end of continued access consumptive material exists
Together, then the brush of potentiometer will be rotated so that the voltage value of inverting input reduces in amplifier, repeats step 2 extremely
Six；
It, will if first waits for that the end of continued access consumptive material and second waits for that the head end of continued access consumptive material is welded together but occurs high-temperature damage
Rotate the brush of potentiometer so that the voltage value of inverting input increases in amplifier, waits for that continued access consumptive material is waited for second by first
The part of continued access consumptive material damage is cut off, and repeats step 2 to six；
If first waits for that the end of continued access consumptive material and second waits for that the head end of continued access consumptive material is welded together, and high-temperature damage does not occur,
Then welding terminates.
