Seam welding of tube
Induction welders have rugged, independent full-bridge IGBT transistors. These transistors are virtually short-circuit proof, considerably boosting reliability and uptime.

Short circuit test
Short circuit testing of Weldac at 513 kHz. The Weldac has proven so reliable, EFD Induction warrants the welders’ IGBT inverter modules and driver cards for a total of five years of operation.
