High-output solid-state welders

The Weldac is EFD Induction's family of high-output solid-state welders based on rugged, reliable IGBT transistor inverters. A complete system, the Weldac consists of a frequency converter, output matching section, busbar, external control system and coil connection.

The Weldac system is available in two basic designs: single-cabinet for welders up to 600 kW; double-cabinet for welders up to 2,000 kW. Weldac is a proven solution for welding stainless steel, aluminum, low-carbon steel and high-strength steel.

Modular design with independent IGBT inverters makes Weldac compact, saving valuable floor space and simplifying in-line integration and retrofitting. The Weldac system can be fitted with induction coils or contact welding heads.
