SOLDERING STATION KIT MODELS These instructions are for the following electronic soldering stations. The model number of the electronic soldering station that you have received, is marked on the end of the carton. Model SL-5K is supplied without an iron. Model SL-5K-40 is supplied with a 40 watt soldering iron, grounded plug, Model SR-6. - Page 3 SOLDER PRACTICE KIT If the soldering station contains a soldering iron, remove only the soldering iron, the soldering station plastic housing, the sponge tray, sponge and the soldering iron holder (funnel) from the station box. Assemble them as shown in Figure 1. You will temporarily use the station parts as a soldering iron stand until you have completed your solder practice and some of the assembly of your...

Page 5: Introduction To Soldering
INTRODUCTION TO SOLDERING Almost every electronic device today has a printed circuit (PC) board. Whether you are assembling a PC board or repairing it, you must understand the basics of working with these boards. A poorly soldered joint can greatly effect small current flow in circuits and can cause equipment failure. - Page 6 SOLDERING A poorly soldered joint can greatly affect small current flow in circuits and can cause equipment failure. You can damage a PC board or a component with too much heat or cause a cold solder joint with insufficient heat. Sloppy soldering can cause bridges between two adjacent foils preventing the circuit from functioning.
- Page 7 Heat Sinking Electronic components such as transistors, IC’s, and diodes can be damaged by the heat during soldering. Heat sinking is a way of reducing the heat on the components while soldering. Dissipating the heat can be achieved by using long nose pliers, an alligator clip, or a special heat dissipating clip.

Page 8: Circuit Operation
CIRCUIT OPERATION THYRISTOR A thyristor is a controlled silicon diode which is not conductive in the reversed direction. It will only conduct in the forward direction when they are triggered by short pulse or steady voltage applied between the gate and cathode terminals (see Figure 8). A thyristor family of semiconductors consists of several useful devices. -

Page 11: Switch Assembly
SWITCH ASSEMBLY Apply the front label to the case as shown in Figure F. Inserting the PC board into the front case will aid in alignment of the label. Cut the black and blue wires so you have two 4” pieces of each color. - Page 12 AC RECEPTACLE ASSEMBLY Cut the 1”, 5/16" dia. shrink tubing into two 1/2” pieces. Solder a 4” black wire to lug #2 as shown in Figure K. Snap the AC receptacle into the opening on the back as shown in Figure L. Insert the line cord strain relief into the case as shown in Figure L.
- Page 13 SOLDERING WIRES TO THE PC BOARD (see Figure N) Solder the black wire from the switch to point A. Solder the blue wire from the switch to point B. Solder the blue wire from the AC receptacle to point C. Solder the black wire from the AC receptacle to point E.
- Page 14 Check your wiring if your readings are different. Measure the resistance from pin #1 on the plug to point A on the foil side of the PC board as shown in Figure P. Switch set to OFF Switch set to ON Measure the resistance from point E on the foil side of the PC board to pin #2 of the AC receptacle as shown in Figure Q.
- Page 15 MOUNTING PC BOARD TO CASE Insert the PC board into the case by aligning the pot and LED with the holes in the case as shown in Figure T. Cable Tie Figure T Use the cable tie to secure the wires as shown in Figure T. Secure the PC board to the case with a washer and nut (see Figure U).
