The GHG 23-66 has a maximum working temperature of 650 degrees Celsius. It offers digital temperature adjustment as well as variable airflow control from 150 to 500 liters per minute in increments of ten. This makes the tool especially suitable for demanding applications, for example, the welding of plastic work pieces such as lorry tarpaulins, pond linings or roof sheeting. The temperature and airflow control can be read quickly and easily on the 1.4-inch LCD display. Four adjustable programs ensure additional ease of use by making airflow and temperature immediately available for the main applications. If the heating element of the GHG 23-66 Professional overheats, it automatically switches itself off, similar to the GHG 20-63 Professional, and is additionally cooled by the blower, which remains in operation.
