HFP preheater operating cycle
Two operating phases are carried out by the HFP preheater:
1. The start-up for a duration fixed at about 35 seconds, phase in which the blower turns, gradually
accelerates to reach the final speed. This phase is used to preheat the torch and the mold. In this phase, the
flames reach about 60 cm high at the start and 20cm at the end.
2. Full power for a period set by the previously set time delay. In this phase, the flames reach 20 to 25 cm in
height (The height increases during preheating). On the timer, the countdown of the remaining time is
displayed.
In the event of a malfunction, first close the gas cylinder valve, then position the handle of the general switch on O.
Let the HFP preheater operate for the entire time delay preselected on the timer.
