Weltronic Decade 5 811-3800 control unit
 |
The Weltronic Decade‑5 811‑3800 is a three‑channel welding control unit that regulates voltage, current, frequency and duty cycle for 230/460 VAC applications. Common failures on this model include burnt or tripped MOSFETs in the power stage, blown input capacitors, and degraded relay contacts due to high duty cycles. Begin diagnostics by verifying the 230/460 VAC supply to the unit, inspecting all input/output connectors for corrosion or loose pins, and checking the status of the internal relays and MOSFETs with a multimeter; then review any error codes displayed on the panel before proceeding to component replacement.[oss-gpt-20b] |
