9. Move PCB in the Y-Axis and align component/lead pattern over the flow well. Use the APS over arm
and cleaning hood to locate, if so equipped. Lock the X-Axis carrier lock.
10. Adjust the Y-Axis stop to set position of PCB in the carrier arms.
• For System 5.2, move the right X-Axis lock to the left until hand stop against center bracket.

11. Remove PCB from carrier arms.
• For System 5.2, unlock X-Axis carrier lock.
12. Turn on machine and let temperature stabilize. Adjust temperature as required.
• For System 5.2 turn on preheater. Adjust temperature as required.
Note
ALWAYS HEAT SOAK FLOW WELLS FOR A MINIMUM OF 15 MINUTES BEFORE FLOWING SOLDER.
13. Set solder flow rate. Starting at zero, set mode switch to continuous.
14. Slowly increase flow rate until solder flows off the edge(s) of the flow well. Flow rate is now set for
that flow well. Different flow rate is required for different size flow wells.

15. Set mode switch to auto (top) position.
16. Place PCB in carrier arms and lock in place with the board lock knobs.
• For System 5.2, tape a type K thermocouple to the PCB using Kapton tape. Plug thermocouple
into the temperature monitor box as required.
• Set the temperature controller on the temperature alarm box to the desired temperature that the
PCB needs to reach.
• Move PCB into the preheater. When alarm sounds, temperature has been met.
17. Move PCB to flow well location.
Mode Switch/Duration/Footswitch
NOTE
UNTIL DURATION (TIME) OF SOLDER FLOW HAS BEEN ESTABLISHED, SET THE DURATION TO THE
MAXIMUM SETTING AND START AND STOP THE FLOW BY USING THE FOOTSWITCH (MANUAL
MODE).
BY USING A STOP WATCH, THE DURATION CAN BE DETERMINED. THE DURATION SETTING IS A
RELATIVE SCALE AND THEREFORE SETTING THE TIME WILL TAKE A COUPLE OF TRIES.
DURATION SCALE IS APPROXIMATELY 0 TO 60 SECONDS.
ONCE THE DURATION IS SET, LEAVE MODE SWITCH IN AUTO. WHEN PCB IS LOCATED OVER THE
FLOW WELL, PRESS START ON THE FOOTSWITCH.
