PRODUCTDESCRIPTION
The Aoyue INT738 Professional Repairing System is a reworking
equipment that combines the functionality of a Hot Air Gun, Soldering
Iron,andSmokeabsorberinonesophisticatedpackage.
Oneofthenotablefeaturesofthisdeviceistheautocoolingprocess
of the Hot Air Gun. This functionality protects the device (and its
components) from excessive heat by blowing air (at room temperature)
uponachievinganyofthefollowingtwoconditions:(1)whenthesoldering
gunremainedidleonitsrestinghandleafteracertainperiodand(2)when
thetemperatureofthedeviceisaboveasafethresholduponturningoff.
Thiswillbediscussedinfurtherdetailtogetherwiththecompletefeatures
inthesucceedingsectionsofthismanual.
Finally, the unique, innovative design with digital control panel and
displayprovidesprecision,safety,andeaseofusetomatchallreworking
requirements.
