Product Specification

DC Welding Rectifier:

Process:
Pro-Weld Model Series is magnetic amplifier type welding rectifier with an efficient electrical design. These welding rectifiers are designed for round the clock welding application. The use of three phase dull wave Silicon Rectifier along with a well designed magnetic amplifier gives a smooth and steady arc with minimum spatter and excellent welding characteristics. Pro-weld Welding Rectifiers are ideally suitable D.C. power source for manual metal arc welding and TIG welding.

Features:

Efficient electrical design.
Two ranges of current selection.
Transformer with 'H' class insulation.
Compact and sturdy with an aesthetic exterior.
Easily maneuverable. Negligible maintenance.
