A significant portion of the high current circuits that are part of electrotechnical equipment use copper buses. Such connections, due to potential environmental factors such as surface oxidation, vibration, or temperature changes, often cannot be made using twisted connections.

The use of silver or brass solders, due to their wetting properties, ensures reliable and durable electrical and mechanical connections.

Induction heaters equipped with surface heating inductors are a safe, fire-free alternative to oxy-acetylene burners, thus not only facilitating service work during repairs of electrotechnical components, but also enabling full process control during manufacturing of such components.
