・ We suggest use with 3S li-po battery to power it.
・ Please note Cut off the power about using 40sec later is suggested,
the heating would still keep around 10sec. Supply constant power too
long time ( more than 40 sec) might reduce the product life.
・Keep the Solder iron tip always with tin. If the solder iron tip is not able
to be with tin on it , please clean the tip with damp napkin or polish it
lightly with sand paper.
・After cut off the power , please do not put away till it is totally cooling
