Welding Rectifier 400
- Manufactured with most robust and rugged mechanical architecture specially suited for rugged management at different environmental conditions
- Configuration of well designed rectifier and transductor unit gives smooth and steady arc with minimal spatter and precise weld
- Output current regulation through electromagnetic transductor resulting stepless and smooth current control
- Welder friendly operation – Vast range of current selection through the medium of conveniently regulator knob & arc force adjustment provided on the front panel or remote current control pendant.
- Highly robust and reliable welding rectifier mainly appropriate for remote and open construction sites
- Easy arc striking is possible with any type of electrodes because of High O.C.V. machine
- Excellent welding output characteristics for all electrodes including 6010 & 7018
- Heavy duty transformer design for trouble free operation over the years
- Double thermal insulated winding hence no burning of coil
