Ultrasonic Plastic Welders : Sonitek S840/S870 and the typical components that are used in the ultrasonic welding process.
| Index | Device | Function |
| 1 | Down Speed Control | Controls horn rate of descent. Return rate is fixed. |
| 2 | WELD TIME Control | Set duration of ultrasonics (0.1 to 4 seconds). |
| 3 | HOLD TIME Control | Set duration of clamping pressure on part after exposure to ultrasonics (.05 to 3 seconds). |
| 4 | Pressure Indicator | Indicates pressure applied to air cylinder. |
| 5 | Pressure Regulator | Adjusts pressure to air cylinder. |
| 6 | Loading Meter | Indicates ultrasonic power |
| 7 | Overload Indicator/Reset Switch | Indicates power supply overload. Also resets overload indicator when optional protection indicator module is on the latched mode. |
| 8 | ON-OFF Switch | Applies main power to system |
| 9 | HORN DOWN/TESTUltrasonics Switch | Horn Down position. Lowers Horn when one palm button is depressed. TEST ULTRASONICS position: Energizes power supply for tuning the system. |
| 10 | Dynamic Trigger (TRIGGER PRESSURE)Control | Controls Pre-clamp pressure prior to ultrasonic energy being applied. |
| 11 | Pilot Light | Indicates when main power is on or off. |
| 12 | Tuning Control | Adjustment for optimizing power supply performance. |
| 13 | Anti Tie-Down Palm (START) Buttons | Activates the system when pressed simultaneously. |
| 14 | Emergency STOP TWIST TO RESET Button | Interrupts welding cycle and causes horn to retract. Pull out to reset. |
| 15 | Column Clamp | Locks head assembly in position |
| 16 | Elevator Knob | Permits vertical movement for gross height adjustment and is counter balanced. |
| 17 | Fuse | Overload protection |
| 18 | Mechanical Stop | Controls depth of weld and acts as safety device to protect horn and fixture. |
| 19 | Base Cable Connector | Connects actuator to base assembly. |
| 20 | Chrome Plated Column | Provides smooth, easy head height and swivel adjustment. |
