Mesin Las Kolarc SAW 1250 DC

  • SAW 1250 DC inverter is a submerged arc welding machine with power unit. Designed especially for all submerged arc welding applications, especially shipyards and steel construction companies.
  • Inverter technology, which supports CC and CV options, enables the user to perform submerged arc welding in all diameters.
  • The digital control panel with 10 program memories automatically stores the welding parameters in its memory. With the Encoder Potentiometer, the welding parameters are adjusted with high precision.
  • With 32Bit DSP Micro-processor, it checks all welding parameters at every stage of the source and provides the most appropriate welding parameters.
  • Thermal protection and the indicator lamp prevent the machine from being damaged if overloaded or air flow through the machine is interrupted.
  • It provides 35% electricity saving in the current drawn from the grid under load according to conventional power units.
  • Smart Cooling Fan Technology works only when needed, reducing noise, dusting inside the machine and energy consumption.
  • Wind Tunnel Design prevents the transport of dust, dirt and sand to the electrical components and electronic cards inside the machine by the cooling air flow, thus extending the life of the machine.
  • Standard intermediate package length is 15 meters, intermediate package length and dust collection unit are optional.
  • Fully compatible with electric generators.
