Purpose & User
This Weller desoldering pump is a hand-operated tool for removing molten solder from printed circuit boards. It suits technicians, hobbyists and repair shops that need a reliable way to clear joints during rework or component replacement.
Thermals, Noise & Power

Accessories & Software Impact
The blue and black body houses a tip with a 0.125 in inside diameter and 0.25 in outside diameter, while the barrel holds 1 fl oz of solder. The tool is ESD safe, protecting static-sensitive parts during use. No software or additional accessories are included.

Questions about this item
How do I install the spring-loaded plunger desoldering pump and what step do people often miss?
Cock the spring-loaded plunger until it locks, position the 0.125 in tip on the molten solder joint, then press the release button; the step users miss is cleaning the tip and barrel after each use so residue does not block the 0.25 in nozzle.
What maintenance or replacement will this ESD-safe desoldering pump need later?
Replace the tip when the 0.125 in inside diameter wears or corrodes, clean the barrel and O-ring regularly, and lubricate the spring-loaded plunger mechanism to keep suction consistent.
What limit appears first during sustained use of this 11.25 in desoldering pump?
The 1 fl oz pump capacity fills quickly during continuous desoldering, requiring frequent emptying before the spring-loaded plunger can reset for the next stroke.
