Hi, I have a Weller fine point 17w model WM17D soldering iron which requires a new tip. Can you please advise as to where they can be purchased. Many Thanks.

If this is the dual trigger Weller gun and your tips are held in place by either set screws or by locking nuts, Just loosen both of the parts that are holding the tip to the gun and then retighten them back up. Soldering iron tips that appear to be tight might not be and this will insure that the tip is indeed tight and also cleans up the connection of the tip to the soldering iron. Oxidation from heating and cooling will cause a tip to not get very hot. Loosen the tip holder and then retighten it. Hope this gets you going again.

if under warranty - return it

The barrel to the soldering iron has a nut on it and the nut unscrews and the whole barrel comes off. The tip then comes out of the barrel.

The TC201Z is a zero crossing switch version of the TC201T. The two handles use the same tips which are the Weller PT series.

You might try getting new bolts that are the next size up. For example #6 x 32 to # 8 x 32. Just tap out the existing holes.

Hello, just loosen the set screws on the end of the soldering gun barrels. Install new tips and tighten the set screw--sung! If your soldering iron requires that the tips have a 90 degree angle on their ends. You can bend them but be very careful because you can break them end off. The tipes are made of copper with some other alloys and the are kinda brittle. You can do. GB...stewbison

Just loosen the screw in the barrel near the tip, then rotate while pulling the tip out. It shouldn't be necessary to remove the tip unless it requires replacement. Hope this helps!

Radio Shack for the new tip.

Here for parts and manual.

Flux the tip, heat the iron, apply solder all over the tip and wipe, while hot, the solder off with fine steel wool.

If the solder is flux core, no need for additional flux

Good Luck
