ET temperature If the but tons are all depressed the display would switch from showing the SET temperature to showing the actual temperature at the tip of the soldering iron The button with the asterisk marking is used to quickly reset the device to the default temperature setting The display would show the letters OFF if the unit has detected that the soldering iron and the main unit are not connected se curely or is not connected If this is displayed turn off the unit and reattach firmly the soldering iron to the receptacle at the main unit SOLDER TIP CARE and MAINTENANCE Tip Temperature If the tip temperature is too high it decreases the life of the tip So we suggest you to use the lowest possible tip temperature when sol dering This not only prolong life of the tip it also quickens heat recov ery and decreases harm to sensitive components Cleaning The soldering iron tip should be cleaned after use by wiping it on the damp sponge found in the soldering iron stand this is to get rid of burnt solder or fluxes that causes oxidation on the tip If the tip has oxi dation apply solder and wipe using the damp sponge repeat these steps until oxidation is removed Regular cleaning is also needed when tips are used for prolonged period of time remove tip from soldering iron and clean it once a week The solder tips are chrome electroplated on the surface and should be bright silver with no flux residue or solder
