To cancel the error you need to switch off and switch on again the machine after eliminating
the error condition.
Antisticking error “Err.StC”.
This error can occurs only when the machine is welding in MMA.
This error occurs if during the welding process ao the start phase the electrode sticks to the
workpiece.
Error solving:
The machine will start again to function after detaching the electrode from the workpiece.

This error occurs when the machine is in thermal overload due to an excessive overheating
Error solving:
The machine will start again to function when temperature will decrease up to an uncritical
value.
