hello:
I have a question with krc4 robot in General Assembly station . sometimes in EXT mode welding,this robot gun stop and happen an error .smartpad display " Incorrect gun position . Initialization,mastering,part thickness,repeat point? ". I see the gun is not completely close,then I change program speed in 50% or 30%,the gun can close and welding .I can not completely solve the problem .This gun sometimes
is ok and sometimes can not welding with the same weld point .Not all weld points happen this problem.I think the workpiece have gap.
