High-Power MFDC Welding Inverter
PRC7300
High-power MFDC welding control delivering from 130 kVA upwards — built for heavy-duty industrial spot, projection and multi-spot welding lines.
Description
The PRC7300 is a 1 kHz mid-frequency inverter scaled for the most demanding industrial welding applications. Modular construction allows configurations from 130 kVA into the multi-hundred kVA range, with secondary voltage starting at 8.9 V depending on transformer pairing. It is the preferred choice for body-in-white, pillar welders, multi-spot installations and large projection welding presses.
