What to do if my Migatronic PI 350 Welding System shows a 'H2O' cooling fault?

If the Migatronic Welding System displays a cooling fault ('H2O'), it might be due to the connection of an incorrect type of torch or the absence of a connected torch. To resolve this, verify that the cooling hoses are properly connected, replenish the water tank, and inspect the welding hose and its branches. You can reset the error message by pressing the MMA keypad.
