Hakko Presto. Soldering Gun. 20w - 130w.
Dual Wattage Soldering Iron.
Normally use the Hakko Presto at 20w. However, it can be heated at 130w
while the switch is pushed. If you want to shorten the heat recovery time
( approximately 20 seconds to get ready for soldering ) or if you temporaily
need high heat capacity to solder a relay or a connector , push the switch
for 5 to 10 seconds.
