ADVANTAGES

• Energy saving and consequent reduction in electric 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.

WELDING SETS ARE NOT ON LOAD ALL THE TIME, YET 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 cannot be wasted and this can be saved only by switching off the set. Since this is not a feasible proposition only the sets are permanently switched on. The ENERGY SAVER is ideal for use with both types viz. Transformer and Rectifier types to SAVE ENERGY.

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 5 seconds (A contactor is to be provided if not already provided). This time interval can be increased or decreased, if the requirement is indicated at the time of ordering. To continue welding, the operator need only touch the electrode to the job 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 without any interruption.

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 hour shift, its 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 shift basis and 300 working days will be around 3000 units and hence cost of the system can be recovered in less than one year.
