Welding Set Energy Saver By Excellent Energy Systems

Excellent welding set energy saver saves considerable amount of energy on weld sets. Normally are kept continuously on, although welding operations are not carried out. During these periods the welding transformer draws the magnetizing current or noload current which is not doing any useful work. Electronic sensing unit detects these non-weld periods and switches off the power to the welding transformer after a preset time interval and hence saves power during these periods.

When welding operation is to be restarted , the operator just need to touch the electrode with the material to be welded and the unit instantly starts the weld which then can be carried on continuously.

The non-weld period power loss on a 12 KVA set will be approximately 1.5 KW to 2.0 KW per hour. So using energy saver there will be a saving of 8-10 units per shift considering normal weld cycle. Which gives a payback period of about 1 year.
