Ersa Dry Sponge
The Ersa Dry Sponge (order no. 0008M) is an
alternative to the wet sponge and can be
beneficial, especially in lead-free soldering.

ensure an efficient process.
Dry cleaning of soldering tips offers substantial advantages.
The soldering tips are not cooled abruptly and contaminat-
ed tips resulting from dirty sponges are avoided. Due to the
slightly abrasive properties of the special wire mesh, passive
layers that accumulated on the tip can easily be removed. Tip
life is thus increased considerably in lead-free hand soldering.
