Air Welding Rectifiers

Additional Details

The Air Welding Rectifiers offered by us are developed keeping in mind the DC welding current requirements of operations that have 3 phase, 50 Hz, AC mains power. These run on voltages ranging from 415 to 440 V, and are manufactured from 100 % copper wound. This equipment is ideal for conducting manual arc welding operations.

These rectifiers are suitable for manual arc welding of:

    Pipes in all positions where welds of high radiographic standard are required
    Non - ferrous metals
    Low - alloy, corrosion , heat and creep resisting, steels
    High efficiency energy saving
    Mild steel at sites where AC welding power may be unsuitable
    The STS may be Supplied with
    Suitable ammeters & volt meters for direct reading of the welding current
    Remote current control devise as optional extras

Features:

    Excellent welding characteristics
    Uses a Three phase, full wave silicon rectifier bridge in combinations with a well designed transductor and output choke to give a smooth & steady arc with minimum spatter and weld bead
    Minimum to maximum current is achievable in a single range thus obviating the need for cumbersome range selection
    Designed for easy arc striking with all type of electrodes
    Surge suppressor device to protect the machine from input voltage spikes
    Built in safeguards to protect against over load or heating
    Excellent for gouging applications also
    Light weight & easily maneuverable
    Easy to maintain
