A & H Electronics welding controllers are industrial power‑control units used to regulate current, voltage and timing for resistance welders. Common failure modes in this class include burned capacitors or diodes on the main power board, degraded MOSFETs causing over‑current protection trips, and faulty I/O relays that mis‑interpret sensor signals. First‑check diagnostics: verify the input supply voltage and polarity; inspect the PCB for visual signs of component damage (burn marks, swollen electrolytics); and review any error codes or fault logs displayed on the controller’s panel before proceeding to deeper troubleshooting.[oss-gpt-20b] |
