Powcon 400SMT Weld Machine

Powcon 400SMT is a multi‑process welding machine (stick, MIG, TIG) that can be configured for single‑phase or 440 V three‑phase operation. Common failure modes reported by users include unreliable power supply switching, inconsistent arc initiation, and overheating of the internal controller board; many owners note difficulty in accessing the main fuse and contactor panels for repair. First‑check diagnostics: verify incoming voltage and phase balance with a multimeter, inspect the main fuse and contactor contacts for corrosion or burn marks, and review any displayed error codes on the control panel before proceeding to internal component testing.[oss-gpt-20b]
