Rated at 480VAC maximum line voltage and 54 KVA line power, the WTC 304-0600L is an IGBT Unit designed for use in industrial resistance welding systems. Manufactured by Welding Technology Corp (WTC) of Farmington Hills, Michigan and made in the USA, this unit carries a rated current of 600A at 10% duty cycle. The type designation 304-0600L is confirmed on the nameplate along with serial number 07378023 and revision E. WTC IGBT units of this type function as high-current solid-state switching assemblies within resistance welding control systems, converting and switching power to the welding transformer or load. The enclosure is a vented metal chassis with visible connector interface boards including a DB15-style connector, terminal blocks, and multi-pin ribbon connections. The internal board reference 703-7984 and document reference 804-4941 are also visible. This unit is intended for integration into a compatible WTC welding control system and is not a standalone welder. Buyers sourcing replacement or spare IGBT assemblies for WTC-based resistance welding lines will recognize the 304-0600L designation from system documentation.
