4.5 Trouble shooting
Problem: No mark at all
Check the following points:
•
Is the line cord plugged in?
•
Are all the other cables plugged in correctly?
•
Has been set a voltage?
•
Is the fuse on the backside of the control in order?
•
Is the marking head moistened with electrolyte?
•
Does a current flow between marking head and negative contact pin?
Note
Only electrically leading surface can be marked!
Painted, anodised or otherwise coated surfaces are not suitable for marking by
electrolytic marking systems.
Problem: Mark is not clear
Check the following points:
•
Is the stencil clean?
•
Wash the stencil and the complete marking head with water to remove the
oxides.
•
Is the surface of the product clean? Wipe off dirt and excess oil with a dry
cloth before marking.
Problem: Black spots around the mark
The stencil was treated inappropriately. It was broken and became permeable
or was torn in another way. In order to solve the problem, the stencil must be
replaced.
In emergency holes in the stencil can be sealed with tape or ÖSTLING stencil
tape until another stencil is available.
