» Magnetic Amplifier Type ARC Welding Rectifiers

Power Source
WTR-Series is magnetic amplifier type ARC welding rectifiers with an efficient electrical design. These welding rectifiers are designed for round the clock welding applications. The use of three phase full wave silicon rectifier along with a well designed magnetic amplifier gives a smooth and steady arc with minimum spatter and excellent welding characteristics.

Warpp arc welding rectifiers are ideally suitable D.C power source for manual metal arc welding and TIG Welding.

Feature

Efficient electrical design.
Two ranges of current selection.
Fully copper wound transformer with 'H' class insulation
Compact and sturdy with aesthetic exterior.
Easily maneuverable.
Negligible maintenance.
Fully powder coated cabinet.
