Total price
When a through hole component is removed, the amount of solder pulled out decides whether the part drops free or the plating tears. This Weller manual desoldering pump takes up the molten solder in one stroke and needs neither a mains connection nor compressed air.
Benefits in use
- Purely mechanical operation without power and without compressed air, so the pump is ready to use in the field and at the test bench with no preparation.
- One handed operation, which leaves the second hand on the soldering iron to keep the solder molten.
- Adds to any soldering bench regardless of station type, no release for a specific station is required.
- Sales unit of 1 piece, so each workstation can be equipped individually.

Applications
Repair and rework of printed circuit boards, prototype work, test areas, training and service cases. Wherever single through hole components are changed and no electric desoldering system is available at the bench.
Compatibility and scope of delivery
One manual desoldering pump is supplied. Soldering iron, desoldering braid and spare tips are not included. In practice the pump is used together with desoldering braid, because residual solder on pads comes off more cleanly that way.
