Certain process deviations from the expected sequence can be detected and brought to the attention of the
user. No assessment of weld quality is made by this process analysis. It is not possible to detect all faults.
This process analysis is not a substitute for diligence and quality control on the part of the user!
If an irregularity is detected, always check the fault indicator on the welding machine and consult the
Troubleshooting → page 15 section.
