## Description

In addition to its famous irons and soldering guns, Weller is also recognized as a leader in advanced electronic rework and repair equipment and irons for sophisticated industrial applications as well as numerous products for DIYers and hobbyists.

Review: Great Size Tip for SMT Electronics and More - I love my Weller WLC100 iron and the variety of tips they offer. I'm a major electronics hobbyist and work in the tech industry. I started off soldering on a rework line, so I've worked with everything from Weller to Metcal professionally and Radio Shack to Weller at home. For the price, the Weller products are far superior to anything I've worked with. Would I love to have an $800 Metcal digital instant-on station at my house? Sure, but I'd much prefer to have $760 to put towards other purchases. These tips are perfect for working with smaller components and pads. They transfer heat fast, even on ground plane pads that seem to take other irons forever. I keep my iron on 3/5 for nearly everything. If I'm removing smaller metal transmitter/receiver covers, I bump it up to 4/5. But, during all my soldering, I do not change tips. I can solder wire joins, smt parts, wave solder legs of SMT chips (with a good amount of flux), and large RC connectors (XT60s), all with the same tip on my iron. The smaller size also allows me to get in between wires and other components easily, without that "Oh crap, I guess I'll be replacing that connector/wire/plastic bit also" feeling.
Review: This DOES fit the WLC100! - I ordered this tip Jan 30, 2010... it arrived today, Feb 4, 2010. Very reasonable shipping time! As soon as I discovered it was in my mailbox, I rushed out to try it out... the old one easily came out, and the new one slid right now. Tightened it down.. then tried it out. With the bigger tip that the WLC100 came with, I had to use a heat setting of about 4, and it was a little bulky for soldering connections on circuit boards, etc. This new tip is absolutely fantastic... DAY AND NIGHT DIFFERENCE in the ease of use. If you need a more precise tip for circuit boards, etc... I highly recommend this tip, it makes soldering those delicate, tighter connections much, much easier. I was hesitant to order this tip because of another reviewer saying it did not fit his WLC100 station... but it does indeed fit perfectly and works great. I used a heat setting of 3 instead of 4 with this new tip, and it works perfectly.

### ⭐⭐⭐⭐⭐ Great Size Tip for SMT Electronics and More

### ⭐⭐⭐⭐⭐ Fine tip
*by H***C on May 12, 2019*

Used to un-solder and replace the light bulbs and stepper motors in my Silverado instrument cluster. The tip had a fine enough point to do the job. It was much better than the tip that came with the Weller WLC 100 -40 watt soldering iron. Both made the job easier with no damage to the circuit board if you have some experience. Since this is the only job I have done with the tip so far I can't say how long it will last, but I can say this is the tip to use on that specific task.
