MIG200DL CO2 MIG Welder Repair Hub
A model-level repair hub for MIG200DL welders, connecting common symptoms with P12, P6, P13, P14, P17 and inverter-drive evidence.
Quick Answer
This model hub connects MIG200DL display, fan, trigger, gas, wire-feed, breaker and unstable-current pages into one service workflow.
- P12 DC540V, P6 DC5V, P13 trigger/jog, P14 feeder output and P17 gas output are the core evidence points.
- No gas, no wire feed and no output are separate failures even when they happen after pressing the torch.
- Breaker-trip pages should be handled before trigger/gas/feed diagnostics.
