Salient Features
- Sturdy & proven construction to withstand extra-ordinary welding environments.
- Fully ThryistorisedThryistorised, infinitely variable current setting over the entire range from 10 Amps to rated current, automatic current stabilization. offers finger touch control.
- MTW rectifier designed for extra smooth arc. reduction of spatier level and high efficiency makes no load losses and input current very low.
- MTW A6 specially for 6010 cellulose, 7018 & 6013 electrodes.
- Low noise cooling fan which is permanently lubricated.
- Modular design of PCB, plug in system reduce down time. PCBs housed in additional steel endorse for protection & preventing the damages.
- Specially designed outer casing treatment which allows exposure to any offshore climatic condition.
Extra Safety: The set is provided with tripping system. If output welding cable short circuits, within 3 minutes the current comes to minimum, thereby saving energy and avoiding cable burning.
