What does error code E20-04 mean on a Migatronic Welding System?
- CCarolyn GraySep 4, 2025
If your Migatronic Welding System displays error code E20-04, it means the control unit is trying to access more data than available in memory. First, try reinserting the SD card. If that doesn't work, replace the SD card with one that is 2 GB or smaller. If the problem still occurs after these steps, contact MIGATRONIC Service.
