However the oxidation characteristics have to be checked and validated for each single application after the
etching. We reserve all rights to compensation for damage to the company caused by corrosion.
Set your SIGNOMAT on „DARK" markings for AC (alternating current). Change the setting of the Signomat
to „LIGHT" marking for DC (direct current).
For most of applications AC (alternating current) can be applied. For AC the etching device has to be set on
DARK.
The properties of an etching with AC are:
Colour: black
Outline definition: good
Depth: low (approx. 3-5 µm/4s marking time)
For etching aluminium DC (direct current) is generally used for all applications. Change the settings of your
Signomat to „LIGHT" (DC) on the front panel. DC current is also used for etching black oxide, gold plated or
similar surfaces. The DC current penetrates the surface coating and the base material will be marked. For
these kind of applications a change between DC and AC current may make sense in order to first penetrate
the surface and to then turn the "light" colouring into a dark marking by etching with AC current in the same
position.
The properties of an etching with DC are:
Colour: clear
Outline definition: diffuse
Depth: deeper (approx. 10 µm/4s marking time)
