Process
300ST 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) Accessiries
