- Stepless transducting controlled Arc welding rectifier, for critical welding using low hydrogen and stainless steel electrodes
- Smooth Arc with feedback and filter transductor choke to minimize ripples and give quality welds and clear X-Rays
- Low Maintenance Three Phase Silicon Rectifier insures a stable D.C. output which improves Arc characteristics
- No rotating parts except cooling fan
- Designed to withstand acidic as well as off-shore weather conditions
- Varitrans provided for setting current. Setting can be changed during welding also.
- No Fuss striking due to start surge current
- Perfect open circuit voltage giving good strike properties
- Large reserve voltage permitting longer welding cables Â
