Welding Set Energy Saver

Welding set energy saver
excellent microcontroller welding set energy saver saves considerable amount of energy on weld sets. Normally welding sets are kept continuously on, although welding operations are not carried out. During these periods the welding transformer draws the magnestising 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.
Welding set energy saver is merely a control unit depending on the capacity of the weld set suitable contactor has to be provided
