The R911171464 (PST625E.133-W) is a weld controller engineered by Bosch Rexroth for resistance welding operations, supporting power ratings up to 155 kVA. The unit incorporates a temperature monitor, an integrated weld timer, and a thyristor power unit for controlled heat generation. It supports a nominal system current of 200 A, a maximum rated current of 230 A, and operates at up to 50% duty cycle. Electrical protection includes a voltage-dependent resistor for overvoltage mitigation. The controller features air blower cooling, operates on 24 V DC supply, and uses a box terminal for connections. Installation is permitted within enclosures or switchgear cabinets, either vertically or on its back, with operational limits of 0–2000 meters altitude and ambient temperatures up to 55°C.
