Sterco Circumferencial Seam Welder has been designed as per IS 4804 and RWMA standards, considering the requirement of Auto silencer, Transformer radiator, Barrels, Cycle rims and Fuel Tank manu-facturers. Welding can withstand highest desined pressures. Machines are availa-ble in standard ratings of 50, 75, 100, 150, 200 and 250 KVA at 50% duty cycle and different throat depths. Machine can be used for Roll spot welder with slight modi-fication in controls depending on the type of welding requirement.

​

CONSTRUCTION:
Sturdy, all welded steel plate fabricated suitably braced and stiffened at points of stress. Transformer fitted inside the body and upper electrode arm directly mounted on to the body. The pneumatic controls are mounted on the side of the machine. All Internal parts are easily accessible. Control stations mounted on the machine are clearly visible and within easy reach of the operator.

​

STANDARD THROAT DEPTHS:
300, 460, 610, 760, 920 and 1070 (other throats available on request)

​

WELDING TRANSFORMER:
Transformer, of a special type, conforming to IS 4804 Part-1 1968 and RWMA Standard, Water cooled, having core of high grade electrical steel, primary and secondary coils of solid electrolytic copper of ample section, heavy duty class ‘F’ insulated, vacuum impragnated suitable for with-standing conti-nuously a temperature of 155°C,

​

COOLING SYSTEM:
Transformer, arms, platters, and electrodes are water cooled. Top and Bottom electrode wheels internally and externally cooled, as required. Internal cooling piping with wheel valves for each circuit is provided in the machine, and discharged to an open drain port for visual observation of flow are provided in the machine,,,,
