Rear view of base unit Fig. 1 V. INSTALLATION & SET-UP (Refer to Figs. 1, 2 & 3) A. Placement of the unit: The GW-10 needs a stable benchtop for set-up. I m p o r t a n t, Using a horizontal b u bble level, adjust the four leveling feet until the machine is properly leveled.

5. When solder falls below recommended level, add solder until the proper level is reached. 6. Replace top insulation, and board holder plate. 7. Turn machine ON at rear of unit: When machine is first turned on, display will show RUN mode and program (00) will show factory set parameters. Heating elements will begin melting solder to set temperature.

INSTALLING OR CHANGING THE NOZZLE: CAUTION: SOLDER IS HOT! CAUTION: USE SAFETY PRECAUTIONS WHEN PERFORMING THIS OPERATION. USE SAFETY GLASSES, FACE SHIELD, HIGH TEMPERATURE GLOVES, & APRON. CAUTION : Nozzle must be completely dry of any moisture (from cleaning etc.) prior to immersing in solder bath.

B. Front Panel: The keys: There are five keys on the controller. [ F ] Function key changes the status of the machine. By pressing this key you can toggle the machine to RUN mode or EDIT mode. In EDIT mode parameters can be changed as required. In RUN mode, the machine is ready for use per the pre-set parameters.

E. Changing Programs: To change to a different program, press [ F ], Prg/EDIT will be displayed, press [ to change the program #, then press [ F ] to switch the machine into the RUN mode. F. Editing Parameters: 1.
VII. REMOVING AND REPLACING THROUGH-HOLE COMPONENTS (ENSURE THAT YOU ARE IN AUTO MODE) A. Prepare board surface and component to be inserted appropriately B. Ensure laser light locator is centered in wave nozzle C. Enter program # desired (in edit mode) Insert D.

XI. TROUBLESHOOTING SOLDERABILITY If all variables and parameters which lead to good solderability are not properly controlled, some typical defects will occur. The description and causes of some common defects are listed below. 1. Poor Wetting: Wetting is the primary factor in achieving good solder joints. A condition when the surfaces to be joined are only partially covered with molten solder, leaving areas of unwetted surfaces, behind is called non-wetting or poor wetting.
Bridging occurs when excess solder shorts two adjacent pads, conductors or leads. XII. TROUBLESHOOTING MACHINE Failure Corrective Measures Solder does not melt Check the circuit breaker, solid state relays and heaters. If the circuit breaker is tripped, turn it on. If the SSR is fused, replace it.
