Welding transformers are used to supply one welding station with 50 Hz AC current during manual arc welding, cutting and overlaying. They are designed to work in areas with a moderate climate, outdoors under a canopy, with an ambient temperature of 40 С to +40 C. The current control ranges are smooth and stepped. A switch is used to change control ranges. Insulation class H according to GOST 8865 70. Natural air cooling. The transformer is equipped with four wheels and a handle for ease of movement. Brackets may be used for lifting by hoisting devices. This increases the ease of use. Welding transformers ensure good ignition and stable combustion of arc.
