MAIN
WELDER FEATURES
 | Direct current three phase welder. In comparison with a traditional welder, it offers the following advantages: |
| Six-phase silicon rectifier with device for checking the correct diodes clamping force. |
| Protection of the diodes against overload, overvoltages, and overtemperatures. |
| Complex pneumatic cycle with low force squeeze. |
| Cylinder with chrome plated stem for heavy duty works and long life; adjustable anti-rotation device. |
| Adjustable double stroke with key control. |
| Lubrication free pneumatic components to eliminates oil mist and to protect the environment. |
| Head descent without pressure for set up and service. |
| Built-in compressed air filter unit and tank. |
| Compressed air disconnecting device. |
| Electrodes speed control valves, shock absorber for end of stroke and air discharge silencers assuring the minimum noise. |
| Two stage electric foot control for clamping and welding pieces only if correctly positioned. |
| Pre-setting for additional double stage electric foot connection for the direct recalling of welding program no.2 (not on units equipped with option 6132). |
| Water-cooled transformers, plates, electrode-holders and electrodes; transformers with epoxy resin coated windings. |
| Flow switch which makes the welder stop if the cooling water does not circulate. |
| TE183 microprocessor control unit. Phase shift welding current adjustment. Synchronous SCR contactors insulated from cooling water circuit with protection thermostat. |
| Standard on all models: two-hand safety control with timer assuring the best safety, and removable key selector. The two-hand control push-buttons are standard on projection models only (thay are available on request on spot welder model). |
| Emergency push-button to stop the machine immediately. |
| Automatic circuit breaker for protection. |
