Heavy Duty Submerged Arc Welder


Weldman WE1000S inverter power source delivers constant current (CC) DC power. This is achieved using energy efficient IGBT inverter technology. These machines render smooth and stable arc for submerged arc welding when coupled with tractor or boom mounted SAW wire feeders. The machines are designed and built with careful layout of power components and cooling arrangement. Hence, heavy duty performance is achieved.


  • Submerged arc welding (SAW)


  • Rugged and High output power for the small size.
  • Designed and built to operate under harshest environment and meets the requirement of quality welding in shipyards, pipelines, construction, petro-chemical plants, oil refinery, offshore works and workshop.
  • Generator friendly (low kVA requirement).
  • Ease of maintenance.
  • Step-less current control in wire feeder unit.
  • Arc-starting enhancement (Arc starting current and duration can be preset in wire feeder unit).
  • MCB for fault protection.
  • Under voltage and Overload protection.
  • Current limit.
  • Control circuit protection by fuse.
