The WELLER T400 is a steel Kleen-Tip sponge and tray assembly designed for tip maintenance during soldering work. The tray holds a moistened sponge used to wipe oxidation and flux residue from soldering iron tips between joints, helping maintain proper tinning and heat transfer. At 2.5 inches in length and weighing approximately 0.26 pounds, the unit is compact enough to sit on a bench or integrate with a soldering station setup. This accessory is installed and used by electricians, HVAC technicians, and electronics technicians who perform regular soldering tasks.
The T400 sponge tray is suited for bench soldering environments in both residential service and light commercial applications. It is typically positioned adjacent to a soldering iron stand for easy tip-cleaning access during work. The steel construction provides durability under repeated contact with wet sponge material and flux residue. It ships as a single unit and is intended for use with compatible Weller soldering stations and irons.
Designed as an OEM-style replacement sponge tray accessory for use with Weller soldering stations and irons that accept Kleen-Tip style tip-cleaning assemblies.
Installation is bench-top placement and requires no tools or wiring. Power down and unplug the soldering iron before handling or replacing tip-cleaning accessories. Dampen the sponge with distilled water before use to avoid thermal shock to the soldering tip. Do not use cleaning chemicals that could damage the sponge material or contaminate the iron tip.
