Lincoln Electric Vantage 300 Vantage 300 Circuit board & screen
 |
The Vantage 300 is a diesel‑engine powered DC multi‑process welder that uses an onboard control PCB (e.g., J31‑4) to monitor engine parameters and shut down on low oil pressure or high temperature. Common failures include a faulty engine protection/idle control board, damaged voltage regulator traces, or blown fuses in the power supply section of the schematic G5388. First‑check diagnostics: verify 120/240 V input and generator output voltages, inspect the J31‑4 PCB for burn marks or loose solder joints, and review any error codes displayed on the screen for “low oil pressure” or “high temp” indications.[oss-gpt-20b] |
