Welding machine welding big loss cause analysis and solution?

Welding machine welding big loss cause analysis and solution? 1, welding machine, welding large loss caused by the fault factors to analysis from the following points: ( 1) Not weld strength or too strong, discharge azimuth migration; Methods: do the discharge in the system correction ( 2) Optical fiber end face don't clean the dust, debris or V groove, or optical fiber fixed shelves have sundry. Methods: after cleaning with alcohol cotton. ( 3) The cut of the fiber end face viewpoint difference is too big; Handling: cutting knife unstable or cutting is bad, the new cutting, or to check whether need to adjust cutting. ( 4) Optical system is a problem, the problem of objective fault led to the budget; Methods: clean the lens, the light source under correction. ( 5) Welding machine program to make mistakes. Methods: from the program
