Appropriate Technology @ Affordable Price
ARC WELDING TRANSFORMER (MMA)
Technical features and benefits:
- Black Hills Welding Transformer is manufactured with complete indigenous design and material with appropriate technology.
- Welding Current Control is from primary side of Welding Transformer. This makes it simple and easy to operate the machine.
- Main Welding Transformer operates at low flux density, which results in low core losses and gives better efficiency of the machine.
- No electronic components are used. This gives it robust, reliable and efficient design.
- Black Hills Welding Transformer is designed for easy maintenance and repairs.
- Enclosure is designed for better circulation of natural air, so it does not require any type of cooling fan. This makes the machine more energy efficient and reliable.
- The machine is ergonomically designed to move with less human efforts.
- Every unit is built for the most efficient and reliable performance as well as long operational life. Yet the commander range in its class is economical in price and operational cost.
