Sigma 60D Lead-Free 60 Watt SMD Soldering Station Real-time LED Display - Features Celsius / Fahrenheit Temperature, Digital Calibration, Extra Plug-in Iron Heating Element, with 6 Iron Tips, Anti-Static Wrist Strap, Desoldering Pump and 50g Solder. 60D --- Digital calibration and compensation: On most soldering stations, adopt a small potentiometer located on front panel or back of case for temp compensation. Operator measures iron temperature with a meter. If temp on the meter is 10 deg above the temp shown on soldering station, operator need to turn the potentiometer and then measure temp again, and turn again. With the digital compensation function in this soldering station, operator just needs to press the white button combinations (easy to set, follow instruction manual with drawings) to compensate 10 deg in one step. --- Plug-in heating element: In most irons, to replace iron heating element, operator uses a 2nd iron to de-solder/remove old heating element and then solder new element. In this soldering iron, the heating element has connection pins at the back. Operator only need to unplug the old heating element and plug new element with hands, no 2nd iron needed. This heating element has a metal tubing outside to make it much stronger than fragile ceramic heating element. --- Celsius or Fahrenheit switch: by press the white button combinations (easy to set, follow instruction manual with detailed drawings), the LED display will show 'C' or 'F' first and then show temperature data corresponding to Celsius or Fahrenheit degree. Operator can easily pick Celsius or Fahrenheit based on preference. ---Well made: by ISO 9001 certified factory specialized in making soldering stations for industrial use to make well-known products and OEM soldering stations for top brands. --- Package includes: Iron station, 60w. Solid Iron holder with sponge and metal wool. 6x Iron tips (1x 900M-T-I, 2x 900M-T-K, 1x 900M-T-B, 1x 900M-T-2.4D, 1x 900M-T-3C). Useful Accessaries: 1 extra metal heating element and 1 extra fuse. 1 roll of solder, 0.8mm, 40g. 1 desoldering suck pump. 1 anti-static discharge wrist band.
