Fault Detection

Make sure all the connection are connected correctly.

• Power indicator off and the cooling fan does not rotating, check whether the fuse was broken or power cable connection off.

• Other abnormal reactions, long time continue use of the machine will cause overheated problems, need to reduce the overheat for a moment.

• Power indicator on and cooling fan rotating but voltage and frequency panel no display, maybe machine problems, please contact us for repairing.

• Welding gun rotating but no power output and can not welding, please check the ground wire connected or not, if correct connected, please contact us for repairing.

• When press the “WORK” button the welding gun does not rotate but has electro- spark when electrode touch with matrix, maybe welding gun motor problems, need to contact us for repairing.

• No argon air flow out of the welding gun (welded areas black color), please check the argon meter and argon tube.
