What to do if my Migatronic Welding System shows H2O error?

If your Migatronic Welding System displays an H2O error, it indicates a cooling fault. Check that the cooling hoses are correctly connected, top up the water tank, and inspect the welding hose and branches. You can reset the error message by pressing the MMA keypad.
