Multiquip 0601823218 Rectifier GAW-180HE - OEM Replacement Part

This rectifier converts AC voltage to DC voltage for the welding output circuit in Multiquip GAW-180HE welder-generators, ensuring stable arc performance across the full amperage range from 50A to 150A. When a rectifier fails, common symptoms include erratic arc behavior, inability to maintain consistent weld penetration, or complete loss of DC welding output while AC power generation continues to function normally.

The GAW-180HE operates at variable power levels depending on electrode size and amperage settings: 3/32" electrodes at 50A draw 2.0 kW, 1/8" electrodes operate at 1.4 kW (80A) or 1.0 kW (120A), and 5/32" electrodes at 150A require 0.5 kW. A functioning rectifier is critical for maintaining these power curves and delivering clean DC output across all operating ranges. Before removing or replacing the rectifier, disconnect all welding loads and cables from the unit and ensure the fuel valve is in the OFF position.
