Furniture Oil Cooled Arc Welding Transformer

Process300ST and 450ST welding transformers per IS1851 (Part !). They are designed yo made the requirements of medium and heavy Constructional work demanding high duty cycle and prolonged use of large electordes. The sets operations at 80 to 100 volts selected by means of two position snap - action rotary switch. the current selector plate is illuminated and a cable when no in use. Two snap action rotary switch enable different current settings each at 80 and 100 volts open circuit voltages to be rapidly selected through and oil cooled welding current requlator.Optional GTWA (TIG) AccessoriesGas & water cooled TIG torches.Tigniter 400 with foot switch.D.C. plug unit of convert AC to D.C.Gas flow meter and pressure requlater.Water cooling system.Technical Specifications Model 300 ST 450 ST Input Supply Voltage Range 390/ 415/440 V2 Lines of 3ph.Supply 390/ 415/440 V2 Lines of 3ph.Supply Frequency 50 Hz 50 Hz Input Current at rated output 415 Supply 48 A 68 A KVA rating : Continuous 12 KVA 16.8 KVA A 60 % duty Cycle 20 KVA 28 KVA Maximum 24 KVA 36 KVA Output Open Circuit Voltage 80 & 100 V 80 & 100 V Welding Current range at 80 OCV 25 to 300A 80 to 450 at 100 OCV 30 to 240A 100 to 360A Maximum ContinuousHand welding machine( 60 % duty cycle ) at 80 OCV 250 A 350 A at 100 OCV 200 A 280 A No. Of setting at 80 OCV 49 42 at 100 OCV 49 42 Qty. of transformer oil required 105 Litres ( approx) 105 Litres ( approx) Dimension ( LxHxB) in mm 860x550x865 860x550x1080 Approx .
