1)  Welding Rectifiers

*  Excellent welding characteristics.  The use of a three-phase, full wave, silicon rectifier bridge in combination with a well designed transductor and output choke gives a smooth and steady arc with minimum spatter and excellent weld bead shape.
*   Easy arc striking :- The machines are designed for easy arc striking with any type of electrode.
*   Unique circuitry to sense the output current and initiate compensatory action.  Especially useful to limit current surge arising during arc striking for preventing burn through and to limit control current in 'no load' condition.
*   Built-in safeguards :  All units are thermostatically protected against overload or overheating due to fan failure or inadequate cooling.  In addition, special "surge suppressor devices" protect the control circuitry from voltage spikes.
*   Reliability :  Made to latest standards,  the equipment can withstand rigorous environmental Conditions.
*   The units are compact, lightweight and easily maneuverable from job to job.
*   Easy to maintain : Since the rectifiers are static machines with no moving parts except for the cooling fan, maintenance requirements are negligible.

3)  Salient Features :-

JAS Series welding transformers are backed by the latest international for optimum cost effectiveness.  Some special features :-

*

Welding current regulation by modern moving core magnetic shunt design
* Step less, smooth and infinitely variable current regulation.
* Adjustment of welding current feasible even while welding is in progress; 
this enables fine current control.
* Open circuit voltage of 90 volts enables welding with all types of special electrodes including low hydrogen type for AC application.
* A special  design provides for excellent dynamic characteristics and thus ensures smooth and optimum metal transfer.
* Very compact in size and light in weight.
* Convenient and easily maneuverable from job to job for rugged welding applications.
* Higher OCV enables use of longer welding cables without problems of welding lead resistance drop.

  *   Suitability for welding with low hydrogen electrodes
* These machines have been specially designed for welding with electrodes which normally require higher OCVs

Optional Extras ( These are provided on specific orders. )

Power Factor Correction Capacitors Often, the electric supply authorities  are particular about the power factor of the equipment installed in their area.  As transformer type welding machines have inherently low power factor, the use of power factor correction capacitors (suggested sizes mentioned under specifications) is recommended.

Ammeter and Voltmeter.
For measurement of the output current and voltage accuracy to Industrial Grade "A", IS : 1248
