  • Page 6 SOLUTION INSTALLATION SOLUTIONi Take your time installing this new control. Be sure that all connections are tight and that no chips get into the control components. A1. UNPACK: Carefully unpack system and inspect for damage. Report any problems to the factory at once. If damage is obvious from outside of carton, photograph the damage and report to carrier immediately.
  • Page 7 SOLUTION INSTALLATION A4. LINE VOLTAGE CONNECTION: A4.1 POWER CABLE HOLE: Drill or punch power cable hole either through the back, side or bottom of the cabinet. Drill or punch a second hole to handle the return cable to the welder transformer. When doing any punching or drilling in the control cabinet, be sure to protect the control components from metal chips.
  • Page 8 SOLUTION INSTALLATION A5. GROUND WIRE: Do not operate this resistance welder without a proper ground wire and connection. The ground wire must be a separate wire that comes into the control through the same conduit as the two power wires. Grounding cannot be from a conduit connection.
  • Page 9 HOOKUP-DIAGRAM. ii. If your switches do NOT have two NORMALLY OPEN contacts, connect them to a Unitrol part #9181-56 ANTI-TIEDOWN INTERFACE. If this board was not ordered with this control it can be easily field installed for this purpose.
  • Page 10 SOLUTION INSTALLATION TRANSFORMER OVERTEMPERATURE SWITCH: If your welder transformer has a thermostat that opens on temperature rise, remove the factory jumper and connect it to terminals #3 and #4. Before connecting, be sure that the contact is CLOSED. Some of these switches are used for turning on cooling water solenoid valves and close on temperature rise.
  • Page 11 SOLUTION INSTALLATION BE SURE THAT THE PIPE FITTING THAT YOU THREAD INTO THESE PORTS IS NON-METALLIC. IT CAN BE PVC OR NYLON. ANY METALLIC FITTING (GALVANIZED, BRASS, ETC.) PUT INTO THESE PORTS CAN EVENTUALLY CAUSE A HOLE IN THE WATER- COOLED JACKET THAT WILL FLOOD THE CONTROL WITH WATER AND DESTROY THE SYSTEM.
  • Page 12 A12. LINE VOLTAGE SELECTION If your line voltage was known to Unitrol when this control was manufactured, it was factory connected to match that voltage. BEFORE TURNING POWER ON, verify that this was done correctly.

The example PULSATION COOL 00CY in section D2.4 3 PULSES of 2 WELD CYCLES each. PULSATION is handy to use when welding thick metal (.120” or thicker). Divide the number of weld cycles found on a welding chart for this thickness by 5 and Set PULSATION COOL = 3.
  • Page 76 SOLUTION IN PRODUCTION Enter the position of the welder transformer TAP SWITCH. If your welder TRANSFORMER TAP # 3← does not have this switch, enter 1. This line will remind the setup person that the transformer TAP SWITCH should be set to this number to match conditions when this welding program was originally set up and approved.
  • Page 77 SOLUTION IN PRODUCTION D4: CHANGING HEAT% ON THE FLY: If you entered values for the MODIFIED HEAT LIMITS (see C3), you can increase or decrease the WELDING HEAT% “on the fly” without going into the welding program. This can be done even if the keypad is in the LOCK position.
  • Page 78 SOLUTION IN PRODUCTION D5. USING THE DIFFERENTIAL PRESSURE TRANSDUCER: SOLUTIONi control, when ordered with the QC package, will wait until the ELECTRODE FORCE has reached the program selected value before welding. Use of this DIFFERENTIAL PRESSURE TRANSDUCER will eliminate the need for having any SQUEEZE TIME in a weld program. This will make the welding sequence as fast as possible while producing high quality welds.

  • Page 84 The trim changes in this RWMA welding program will stay in this program for future use. SOLUTIONi IF YOUR CONTROL DOES NOT HAVE QC IN THE MODEL NUMBER, YOU HAVE TO BE IN CONSTANT VOLTAGE MODE (PROGRAM 997, ENTER, 11).
  • Page 85 SOLUTION IN PRODUCTION If you have a TAP SWITCH on your welding transformer, to up or down one number and try again. Repeat until the control does not show this phrase. If you do NOT have a transformer TAP SWITCH on your welder, you can ignore this recommendation.
  • Page 86 SOLUTION IN PRODUCTION 7. ELECTRONIC PRESSURE REGULATOR OPTION 9181-16 This option sets an electronic pressure regulator to provide the requested air pressure in response to the TIP FORCE line in a program. If this option was ordered with your control the system is factory set to operate. 7.1 EQUIPMENT: An electronic pressure regulator has been provided with your control.
