DC Rectifiers

Model : DCR 300,..

Description:

Stepless transducting controlled ARC Welding Rectifier. Especially for critical welding using low hydrogen and stainless steel electrodes. The unique smooth ARC with the feedback and filter transducter choke to minimise the ripples and give quality welds and clear X-Rays. Varitrans is provided for setting the current throughout the entire range, settings can also be changed during welding.

No Fuss striking due to start surge current. Perfect open circuit voltage gives good strike properties. Large reserve voltage permitting longerwelding cables.
