The power setting is probably too high so reduce the power. Also check the electrolyte being used is correct for the material you are marking. Please refer to the electrolyte selection chart or call us for advice on electrolyte selection.

To ensure the contrast and clarity of your mark is maintained it is important to inspect the connections between the marking head and the output cables and the earth connection to make sure they are clean and free from corrosion and dried electrolyte. This should ideally be done weekly. They can be cleaned with an abrasive material such as Scotchbrite. In addition to this we recommend washing the marking head out ideally at the end of each day.

Some of our electrolytes require neutralizing and we can supply neutralizer in a handy pack for ease of use.

If it has, this is typically due to a short circuit caused by touching the electrode of the marking head on to the component or earth connection. Simply replace the AC fuse.

Titanium marks very quickly. There is a specific technique for oxide marking this metal. Low power setting, 1 or 2 on most of our marking units. Marking cycle of 0.25 – 0.75 seconds. Do not pre-wet the marking face or stencil with electrolyte. Keep the felt pad just damp with electrolyte and use a very firm marking pressure and mark the part in one go without moving the marking head if possible.

This can be done, however, the oil may block the stencil over time if not changed regularly enough.
