The WELLER T0051384099 is a replacement brass wool ball designed for use with the WDC series dry tip cleaner. Sold in a two-pack, each ball measures 1.25 inches in length and is constructed from brass, providing effective mechanical cleaning action that removes oxidation and solder residue from iron tips without the thermal shock associated with wet sponge cleaning. This accessory is installed and replaced by electronics technicians, HVAC control board service techs, and trade professionals who rely on a clean tip for consistent solder joints and reliable connections.
This replacement wool ball is suited for bench service environments where tip maintenance is performed regularly. The dry cleaning method preserves tip tinning and extends tip life compared to damp sponge alternatives. Keeping a supply of replacement wool balls on hand ensures the WDC dry cleaner remains effective throughout a full service day without interrupting workflow.
Designed for use with the WELLER WDC Dry Cleaner as a direct replacement wool ball insert.
Power down and unplug the soldering station before replacing the wool ball to avoid accidental contact with a hot tip. Remove the spent wool ball from the WDC dry cleaner housing and insert the replacement, pressing it firmly into place. No tools are required for this replacement. Dispose of used brass wool in accordance with local waste handling practices, as it may retain flux and solder residue.
