Weldlogic GRJW860-A Circuit Board

The Weldlogic GRJW860‑A is a main control board used in AWS‑200N and other automated welding systems to manage power delivery, arc stability, and safety interlocks. Common failure points on this class of boards include burnt capacitors or electrolytic failures near the high‑current driver ICs, degraded solder joints on the MOSFET array, and damaged protection diodes that can cause erratic weld start/stop behavior. First‑check diagnostics should verify input power integrity (12 VDC rail and 240 VAC supply), inspect for visual signs of component damage or overheating, and review any error codes displayed by the system’s diagnostic LED panel.[oss-gpt-20b]
