Hexacon Mdl. 1002PBS Therm-O-Trac Soldering Station. (Inv #7476, #7477) Therm-O-Trac is designed to give the industry's most stable temperature control during the workcycle and less than ±10°F variance at idle temperature. Temperature is controlled by a thermistor positioned at the working end of the tip. It continually senses temperature and corrects for temperature variations immediately by adjusting the power through a closed loop, zero voltage switching circuit. Power Boost Model 1002PBS delivers high quality solder joints on multi-layer boards with ease and without damaging the board or components. It has the high heat capacity necessary to provide a completely filled hole. Soldering dwell time is reduced to a minimum and there are no lifted pads, measling or extra high tip temperatures. Hexacon's Power Boost System solders up to 4.5 times faster than conventional stations on multi layer boards.
Features:
Temperature: Variable temperature range (525°F to 850°F) can be set for any temperature in range.
Safety: Therm-O-Trac does not produce levels of EMI, RFI, ESD, electrical or any other energy forms detrimental to sensitive devices during soldering. The station design and construction eliminates any possibility of ESD damage.
Voltage Leakage: Steady state voltage leakage is a potential risk in many irons after prolonged use. In the Therm-O-Trac, "Posi-Ground¨, a positive tip grounding technique developed by Hexacon, prevents leakage potentials greater than two millivolts - well below the damage level for voltage sensitive components. The power supply for the low voltage element is fully isolated.
Magnetic Fields: Therm-O-Trac's solid state, electronic switching does not produce a magnetic field.
Includes a used J601X tip. Power req: 110/120VAC, 50/60Hz, 1A, 100W. Good used condition, checked, guaranteed. Price: $129.00 ea
