CEA Treo 1800

Wide versatility and portability are the main features of single-phase multifunction synergic power source TREO 1800 Synergic. Based on the most modern IGBT inverter digital technology, TREO 1800 Synergic allows high quality MIG-MAG welding on all materials, by also granting optimal performances both in TIG by “lift” mode and in MMA welding. Innovative, versatile, light, easy-to-carry, user friendly, TREO 1800 Synergic, thanks to its very high technological conception, is absolutely unique for all external or internal maintenance jobs, car body repairs, agriculture and very light fabrication works.


  • Multifunction power source with optimal welding characteristics in MIG-MAG, MMA and TIG
  • Digital control of all welding parameters with preset synergic curves according to used material, gas and wire diameter
  • Ability to store personalized welding parameters up to 99 JOBS
  • Built-in polarity changeover facility for most common gas and gasless wires
  • Central Euro connection for the torch
  • Innovative and user friendly design
  • Metallic main structure with shock-proof fibre compound front frames
  • Control panel protected against accidental impact
  • IP 23 protection class and dust-proof electronic components, thanks to the innovative “tunnel” fan cooling system, allow use in the toughest work environments
  • Easy to read and adjust sloping front panel highly visible from any direction
  • Professional 2-roll wire feeding mechanism for a precise and constant wire driving
  • Double groove rolls replaceable without any tool
  • Graduated knob to achieve the most correct value of the wire pressure, which remains unchanged also after any arm opening and closing
  • Wire spool lodging up to 200 mm Ø max
  • Possibility of utilizing 300 mm Ø coils by means of the Retrofit Kit (Optional)



VRD device reduces open circuit voltage below 12 V and grants additional safety protection for the operator in all highly hazardous environments.


MMA welding

  • Adjustable Arc Force to select the best welding arc dynamic characteristics
  • Adjustable Hot Start to improve the arc striking with the most difficult electrodes
  • Electrode Antisticking function


TIG welding

  • DC TIG welding by “lift” mode striking to minimize tungsten inclusion
