Usage: Normally use the HAKKO PRESTO at 20w. However, it can be heated at 130w while the micro-switch is pushed. If you want to shorten the heat recovery time (approximately 20 seconds to get ready for soldering) or if you temporarily need high heat capacity to solder a relay or a connector, push the switch for 5 to 10 seconds. Push the button for 130W. *Do not push the button over 30 seconds. Product Features: ~ The HAKKO PRESTO features two operating wattages-20W and 130W, which can be switched by simply pressing a button according to the component size you want to solder. ~ A ceramic heater which quickly increases the temperature. ~ A high- performance micro-switch ~ “Everpoint” tip achieves excellent corrosion resistance thanks to our unique manufacturing method (Several 10 times the life of copper tips) ~ Made of SUS304 for high resistance to rusting and oxidation caused by heat ~ A flange which prevents the heat from being transmitted to the grip.
