SP40NKUS
High-performance LED soldering iron (view larger).

Delivering the ultimate soldering experience, the Weller SP40NKUS Soldering Iron Kit includes the SP40N co-molded hand soldering iron with three built-in LEDs for superior accuracy and application illumination. This medium duty iron produces 40 watts (up to 900 degrees F) for joining 12 AWG wire or smaller. It's ideal for use on electrical/electronic components, audio equip., RC hobbies, and more.

A round, soft grip, non-slip handle design helps relax the hand during extended use, and it easily provides a mechanism to roll and position the tip for application needs. A triangular front housing contains the high temperature long-life LEDs, which produce 25 lumens of light. Once the tip position is determined, the hand naturally gravitates to the triangular area to provide a more stable and effective way to control the tip position. It features a stainless steel heater construction, easily tip changes, and a durable cord with a 5-foot reach. This soldering iron is backed by a 7-year limited warranty.

5.0 out of 5 stars Weller soldering iron 40 watts
By Mike on May 31, 2019
Excellent heat quality used it to solder 14awg wire onto a 12v car adapter. Heated up to full temp in 90 seconds, maintained temperature when soldering. Worth the few extra dollars. Heavy duty tips made well. I have used the 5.00 cheap soldering irons and they do not produce enough heat to melt solder unless you give them 4 min to heat up and the heat dissipates rapidly if soldering anything larger then micro connections. This is a true 40-watt iron like they used to be made 20 years ago. Stay away from the cheap kits for 5.99 or similar.
