Weller EC305 Swiss Cheese Sponge
The Weller EC305 is a Swiss cheese-style tip cleaning sponge designed for soldering applications. It provides good resistance to fraying during regular tip wetting. This accessory suits technicians and hobbyists who need reliable tip maintenance. It helps keep soldering iron tips clean for consistent heat transfer.
Replaces standard flat sponges
The porous Swiss cheese structure offers more surface area than a conventional flat sponge. Upgrading is worthwhile when tip cleaning feels slow or the old sponge breaks apart quickly. The open-cell design holds water effectively for repeated wetting cycles. It reduces the need for frequent sponge replacement during long sessions.
Handles daily bench soldering
The sponge comfortably manages routine tip cleaning for through-hole and surface-mount work. It runs out when the pores clog with heavy flux residue or the material degrades from heat. Users doing high-volume production may need to rotate sponges more often. The 305 model fits standard Weller sponge trays.

Questions about this item
How much bench space does the EC305 Swiss Cheese sponge occupy?
The compact Swiss Cheese-style sponge fits in standard soldering iron stands without requiring extra bench area.
What is the correct way to wet the EC305 sponge before first use?
Saturate the sponge with distilled water until fully damp, then squeeze out excess — using it dry damages tips and is the most common mistake.
When should the EC305 sponge be replaced?
Replace it when the porous structure collapses, fraying appears despite the resistant design, or it no longer holds enough moisture for effective tip cleaning.
