TERCO D.C. Welding Rectifiers Forced Air Cooled are used as power Source for manual metal Arc Welding (MMAW) jobs with bare & coated electrodes suitable for ferrous and non ferrous metals. These welding rectifiers are also used as an alternative to DC welding generators and even have an edge over DC welding generator as there are no moving parts in welding rectifier except the cooling fan which ensures almost nil maintenance cost, besides its low initial cost as compared to generator. These rectifiers can also be used as power source for plasma Arc cutting gas shielded arc welding & for Tungston Electrode (TIG) welding to do the welding of stainless steel copper alloys. Submerged Arc Welding and also suitable for carbon Air Arc Gouging.

TRANSFORMER
Specially designed Transformer conforming to IS : 4559 1993 having core of high grade electrical steel Welding current is regulated by latest transconductor type control continuous current variations and 3 phase full waive bridge circuit used in current Rectifier for higher efficiency and steady form, Welding rectifiers are mounted on three solid rubber wheels (Front wheels swivelling & steerable type by means of draw bar) for easy portability, bye bolts had been provided to lift the machine.

 

PROTECTION PROVIDED

  • Both main & control rectifier protected against surges by semi conductor devices for positive protections.
  • M.C.B. is provided for protection of the current controller.
  • On-Off switch is provided on the front panel.


OPTIONAL
Remote control with required cable length, voltmeter, Amp. meter and a set of welding accessories etc. can also be provided at an extra cost.

ADVANTAGES

  • Improves power factor and saves energy.
  • Does not create unbalanced voltage fluctuation on the other load connected Simultaneously.
  • Lower demand of primary current for starting.
  • Very low running and maintenance cost.
  • Extremely low ripples in the output.
