Heat shrink machine is slow or unable to rise to a higher temperature (above 160 degrees Celsius) What is the reason?
Line heater is the main power line through a magnetic switch and then to electric suction pipe, it should be sucked magnetic switch detects the contacts are normal. If the line does not pass one of the phases, the above phenomenon occurs. If suction magnetic switch normal, then check the meter to see if the machine each phase ohmic values are the same. If the normal should be shorted. If all phases are turned on but still abnormal line or heating pipes, replace the heater.
