Heavy Duty Gmaw / Mig Welders


Weldman ‘V’ series inverter power sources deliver constant voltage (CV) DC power. This is achieved using energy efficient IGBT inverter technology. These machines render smooth and stable arc for GMAW / MIG welding with solid and flux cored wires of various sizes and types. Weldman WE4R and WE4R2 are the suitable wire feeders to work with ‘V’ series power sources. The machines are designed and built with careful layout of power components and cooling arrangement. Hence, heavy duty welding at higher current is achieved.


  • MIG / MAG / CO2 welding (Solid wire)   >   FCAW welding (Flux cored wire)


  • Light weight, compact and yet reliable.
  • 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.
  • Welder friendly controls.
  • Digital display for monitoring of voltage.
  • Step-less voltage control in the wire feeder.
  • Adjustable electronic inductance control for smooth and spatter less welding.
  • Wire inching and gas purging facility in wire feeder.
  • Selection of torch switch function either 2-stroke (manual) or 4-stroke (trigger hold) in wire feeder.
  • MCB for fault protection.
  • Under voltage and Overload protection.
  • Current limit.
  • Control circuit protection by fuse.
