Weldac

High-output solid-state welders

Weldac - 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.

Welding with induction heating

EFD Induction offers a full range of solid-state welder systems fitted with induction coils or/and contact heads. Our welding solutions are primarily found in the tube and pipe industry.

 

All our welders have rugged, independent full-bridge IGBT transistors. These transistors are virtually short-circuit proof, considerably boosting reliability and uptime.

 

You also get more output thanks to our continuous electronic load matching. This secures full power output across a wide range of tube sizes (OD 3/8”-26”/10mm-600 mm), ensuring maximum welding speed for each size.

 

Moreover, you can reduce your power consumption. The efficiency from input at the rectifier to output at the coil is, at least 85-87 percent. And the use of diode rectifiers results in a high, constant power factor (0.95) at all power levels—thereby eliminating the need for costly reactive power compensation capacitors.
