Rectifiers

Description

Welding Power sources designed for smooth dc output. Used for Stick (MMAW) welding and TIG (GTAW) welding.

Applications

(MMAW) General Fabrication, Repair, Maintenance, Structural Steelwork, Process Plant, Shipbuilding, etc.

(GTAW) Suitable for use in mechanized and automated equipment, Automobile, Aerospace, Power Generation, Chemical Plant Equipment, Nuclear Plants, Food processing machinery, etc.

Features

The optimized design of the transductor ensures a smooth & steady arc with minimum spatter.
Full-wave silicon rectifier with excellent welding characteristics.
High open-circuit voltage to accommodate easy arc striking of a wide variety of welding electrodes.
High-quality CRGO laminations ensure very low idle power consumption.
Fully aluminum (F-class)wound with near-perfect design ensures low energy consumption with trouble-free service life.
Robust design with powder coated chassis ensures long life in site conditions also.
