Arc occasionally breaks during the welding process
Cause: Break voltage (Uco) is set too low
Remedy: Raise the break voltage (Uco) in the Setup menu
Cause: Voltage of the electrode too high (e.g. grooved electrode)
Remedy: Use alternative electrode if possible or use power source with higher welding
power
Rod electrode tends to stick to the workpiece
Cause: Value for dynamic parameter (manual metal arc welding) set too low
Remedy: Set a higher value for dynamic parameter
Poor-quality weld property
(strong spattering)
Cause: Incorrect polarity of the electrode
Remedy: Reverse the polarity of the electrode (observe manufacturer guidelines)
Cause: Poor ground earth connection
Remedy: Attach earthing clamps directly to the workpiece
Cause: Non-viable setup setting for the selected process
Remedy: Optimize the setting for the selected process in the Setup menu
Tungsten electrode melts
Tungsten inclusions in the parent material during the ignition phase
Cause: Incorrect polarity of the tungsten electrode
Remedy: Connect TIG welding torch to the (-) current socket
Cause: Incorrect shielding gas, no shielding gas
Remedy: Use inert shielding gas (argon)
