Balck Hills Welding Transformer is designed with latest technology and scientifid approach.
Black Hills Welding Transformer is manufactured with complete indigenous design and material with appropriate technology.
No electronic components are used. This gives it robust, reliable and efficient design. This makes maintenance and repairs easy.
High quality stamping and winding wire is used in the machine, which reduces the losses of electricity and makes the machine more energy-efficient.
High quality winding insulation increases the life of the transformer.
The main benifit of SMART series is the possibility to use them with one or two phase power supply.
Black Hills welding transformers are designed with special sheet-metal body cover, which ensures that fan mechanism is not required for cooling. This design saves the electricity, reduces the cost and increases the reliability of the machine.
Due to special design, Black Hills SMART welding transformers are easy to lift and portable.
Every unit is built for the most efficient and reliable performance as well as long operational life. Yet the SMART range in its class is economical in price and operational cost.
