The Master Appliance Master ProHeat STC heat gun, No. PH-1600, brings work surfaces up to target temperatures quickly. It also provides a continuous surface temperature reading, so users can work at the upper limit of the target temperature cure zone, speeding up the heating process to get the job done quickly. To use, turn on and point the PH-1600 at a work surface. The unique Laser Targeting System calculates the proper field of view for accurate temperature measurement and displays work surface temperature. Then simply dial-in a target temperature and watch while the displayed surface temperature rises to reach the target. Once your target temperature is reached, the heat gun automatically regulates the heater to maintain the target. Temperature output is adjusted to compensate for any change in the distance from the work surface. To prevent a change of the temperature and airflow you have dialed in, the unit’s unique Proloc supervisor locking system can lock the controls.
