PROTECTION :-
PROTECTION CLASS IP 22-23: This is latest insulation class in the international standards which is in use only in Inverter based welding equipment & first time introduced in India by MEMCO.
OVER LOAD PROTECTION THERMAL: This is a safety device for the transformer of a welding rectifier which gets cuts of automatically if the transformer gets over loaded.
HOT START: This is a facility to get additional current for a short period to re-melt the craters from the previous electrode avoiding slag inclusion.
ANTI STICKING: The moment electrode shorted at the work place, an extra current isinjected into the electrode for prevention of freezing as well as to start with the deep penetration welding.
EXTRA SAFETY : The set is provided with tripping system. If o/p welding cable short circuits, with in 3 min. the current comes to min. i.e.,10A so no cable burning.
NO-LOAD LOSESS: It is found that our thyristorised controller power source is consuming only 2.25A ideal current approximately.

WELDING TRANSFORMER
TRANFORMER UNIT [ OIL & AIR COOLED ]
OIL COOLED OCV 79/80/100
AIR COOLED OCV 70/80/100
CONSTRUCTION OF TRNASFORMER
The basic construction of transformer is 100% Cu Wound With CRGO lamination & H class insulation.
The life of the Cu is 3 to 4 times more than the Al & also it withstands at more temperature than the Al.
CRGO lamination is preferred because of its high efficiency i.e., it consumes power Compared to CRNGO or BLACK SHEET Lamination.
The ‘H’ class insulation is preferred because its with standing capacity is more i.e., Up to 180° to 210° C than compared to ‘F’ class or ‘B’ class insulation.
