Hypertherm 041246 is a printed circuit board assembly that houses the relay module used in HySpeed HD1070/HT2000 plasma arc cutting systems. Common failure points on this board include burned or cracked relay contacts, damaged voltage regulator traces, and degraded solder joints to the power input pins; these often manifest as intermittent cut‑off or failure to energize the plasma torch. For initial troubleshooting, verify that the 24 V DC supply is within spec and stable, inspect the PCB for visible burn marks or broken traces, and test the relay coil resistance against manufacturer tolerances. If those checks are clean, proceed with a continuity scan of the relay contacts and a scope probe on the control line to confirm proper signal timing.[oss-gpt-20b]
