PRODUCTDESCRIPTION

The Aoyue INT738 Professional Repairing System is a reworking

equipment that combines the functionality of a Hot Air Gun, Soldering

Iron,andSmokeabsorberinonesophisticatedpackage.

Oneofthenotablefeaturesofthisdeviceistheautocoolingprocess

of the Hot Air Gun. This functionality protects the device (and its

components) from excessive heat by blowing air (at room temperature)

uponachievinganyofthefollowingtwoconditions:(1)whenthesoldering

gunremainedidleonitsrestinghandleafteracertainperiodand(2)when

thetemperatureofthedeviceisaboveasafethresholduponturningoff.

Thiswillbediscussedinfurtherdetailtogetherwiththecompletefeatures

inthesucceedingsectionsofthismanual.

Finally, the unique, innovative design with digital control panel and

displayprovidesprecision,safety,andeaseofusetomatchallreworking
