WELDING SET ENERGY SAVER
(FOR TRANSFORMER AND RECTIFIER SETS)

SYNOPSIS MODELS : WSES-SA(SEMI AUTOMATIC) AND WSES FA(FULLY AUTOMATIC) SCOPE FOR SAVING ENERGY ADVANTAGES FEATURES

SYNOPSIS: WELDING SETS ARE NOT ON LOAD ALTHOUGH THEY ARE PERMANENTLY KEPT SWITCHED ON. During the non use period the welding set consumes power, although at a lower level compared to the power consumed when welding operation is going on. However the non-use period power is quite substantial and this Energy can be saved only by switching off the set manually. Since this is not a practical proposition, the sets are permanently kept switched on.

The ENERGY SAVER is ideal for use with both types viz. Transformer and Rectifier types to SAVE ENERGY.A contactor is to be provided, if not already provided to carry out the switching operation.

In the SEMI AUTOMATIC MODEL,the Electronic unit automatically switches off the set, by cutting off supply to the Contactor, when the welding set is not in use for the factory preset time interval of about 15 seconds. This time interval can be increased or decreased, if the requirement is indicated at the time of ordering. TO CONTINUE WELDING, the set will have to be switched on manually using a micro switch or reset button provided.

In the FULLY AUTOMATIC MODEL, the operator need only touch the elctrode to the job to CONTINUE WELDING and the electronic unit automatically switches on the Welding set by providing coil supply to the Contactor, so that welding operation can be carried on. A system by-pass facility is provided, so that in case of any problem with the Electronic unit Welding operation can be carried on.

SCOPE FOR SAVING ENERGY

In a welding set of 30 KVA, the no load power consumption is around 1.00 K.W. Generally in an 8 hr. shift, it is possible to save around 5 units, as the total non-welding period is likely to be around 60%. The savings per year on 2 shifts basis and 300 working days will be around 3000 units and hence cost of the system can be RECOVERED IN LESS THAN ONE YEAR. Of course the saving will be depend upon the capacity of the set, the total non use period etc.

ADVANTAGES

• ENERGY SAVING AND CONSEQUENT REDUCTION IN ELECTRICITY BILL.
• REDUCTION IN MAXIMUM DEMAND AND CONSEQUENT REDUCTION IN MAXIMUM DEMAND CHARGES.
• IMPROVED POWER FACTOR OF THE SYSTEM
• EXTENDED LIFE OF WELDING SETS DUE TO LOWER HEATING UP OF TRANSFORMER

FEATURES

• SIMPLE TO CONNECT AND USE
• CAN BE USED WITH SINGLE PHASE OR THREE PHASE SETS ON SETS WORKING ACROSS TWO PHASES

OPTIONAL

• PROTECTION AGAINST FAILURE OF WELDING SET DUE TO SHORTS IN THE WELDING CABLES
