Chapter 9 Troubleshooting
This chapter explains the typical troubleshooting for the welding power source.
The cause of problems can be categorized as below:
• Mechanical problems (e.g., problems of driving mechanism of the wire feeder)
• Electric and control problems
• Operational errors
A problem may become complicated as a result of mix of multiple causes. If a problem has occurred in the welding power
source, it is necessary to identify its cause and address it appropriately.
For question concerning problems, contact your dealer.
