Ideal for both ferrous as well as non ferrous metals, DC welding rectifiers are extensively used as power source for manual metal arc welding (MMAW) jobs with bare & coated electrodes. These welders are also used as alternative to DC welding generators. The welding rectifiers have no moving parts except the cooling, which ensures greater stability and low maintenance cost. 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. The on-off switch on the front panel provides greater added safety to the users.
DC Welding Rectifiers can also be used as power source for plasma arc cutting gas shielded arc welding & for Tungsten Electrode (TIG) welding for welding of stainless steel copper alloys. Also suitable for special welding applications such as submerged arc welding and carbon air arc gouging.
Sterco also offers optional accessories with the welding set such as remote control with required cable length, voltmeter, Amp. meter and a set of welding accessories etc.
The heavy duty transformer with core of high grade electrical steel Welding current conforms to IS : 4559 1993. Rectifiers have a 3 phase full waive bridge circuit for higher efficiency and steady form. Rectifiers are mounted on three solid rubber wheels (Front wheels swiveling & steerable type by means of draw bar) for easy mobility, bye bolts have been provided for lifting the machine.
