Rectifying faultsChecklist for rectifying faults7 Rectifying faultsAll products are subject to rigorous production checks and final checks. If, despite this, something fails towork at any time, please check the product using the following flowchart. If none of the fault rectificationprocedures described leads to the correct functioning of the product, please inform your authoriseddealer.7.1 Checklist for rectifying faultsNOTEThe correct machine equipment for the material and process gas in use is afundamental requirement for perfect operation!Legend Symbol DescriptionFault/CauseRemedyCoolant error/no coolant flowing Insufficient coolant flow Check coolant level and refill if necessary Air in the coolant circuit see chapter "Vent coolant circuit"Wire feed problems Contact tip blocked Clean, spray with anti-spatter spray and replace if necessary Setting the spool brake (see "Setting the spool brake" chapter) Check settings and correct if necessary Setting pressure units (see "Inching wire electrodes" chapter) Check settings and correct if necessary Worn wire rolls Check and replace if necessary Wire feed motor without supply voltage (automatic cutout triggered by overloading) Reset triggered fuse (rear of the power source) by pressing the key button Kinked hose packages Extend and lay out the torch hose package Wire guide core or spiral is dirty or worn Clean core or spiral; replace kinked or worn coresFunctional errors Machine control without displaying the signal lights after switching on Phase failure > check mains connection (fuses) No welding performance Phase failure > check mains connection (fuses) Various parameters cannot be set Entry level is blocked, disable access lock (see chapter entitled "Lock welding parametersagainst unauthorised access") Connection problems Make control lead connections and check that they are fitted correctly. Loose welding current connections Tighten power connections on the torch and/or on the workpiece Tighten contact tip correctly40099-005208-EW50110.04.2014
Rectifying faultsError messages (power source)7.2 Error messages (power source)NOTEA welding machine error is indicated by an error code being displayed (see table) on thedisplay on the machine control.In the event of a machine error, the power unit is shut down.The display of possible error numbers depends on the machine version(interfaces/functions).• Document machine errors and inform service staff as necessary.• If multiple errors occur, these are displayed in succession.Error Category Possible cause RemedyError 1(Ov.Vol)Error 2(Un.Vol)Error 3(Temp)Error 4(Water)Error 5(Wi.Spe)Error 6(gas)Error 7(Se.Vol)Error 8(no PE)Error 9(fast stop)Error 10(no arc)Error 11(no ign)Error 14(no DV)Error 15(DV2?)Error 16(VRD)Error 17(WF.
