Industrial WI05-I31A IGBT DC Resistance Inverter

The WTC/Medar WI05-I31A IGBT DC resistance inverter is an industrial power module that delivers fast, precise DC weld current switching and regulation for resistance welding systems. Designed for robotic weld cells, automotive body assembly lines, and automated resistance welding equipment, it integrates with robotic welding and weld controller systems to provide stable DC welding current and repeatable weld quality. Key specs include 480 VAC input at 50/60 Hz, IGBT technology for DC weld power switching and regulation, industrial chassis mounting, and approximate dimensions of 30 x 17 x 16 inches with a weight of about 54 lb. This unit supports replacement, retrofit, and repair in automated manufacturing and welding operations, and is commonly used alongside other replacements such as the WTC WI05-I20A, Medar IGBT DC Weld Inverter Module, and Bosch Rexroth MFDC Welding Inverter Unit.
