Five Attachments For Your Existing Catalyst
Three soldering tips, hot knife and hot blower refresh a compatible LX-770 or LX-771 assembly. Head catalyst and deflector are separate from this five-piece set.

The LX-TIP-D is a five-piece attachment set for Lexivon LX-770 and LX-771 butane tools. It supplies standard, diagonal and chisel soldering tips, hot knife and hot blower for contact soldering, hot cutting and hot-air work.
Three soldering tips, hot knife and hot blower refresh a compatible LX-770 or LX-771 assembly. Head catalyst and deflector are separate from this five-piece set.

Threaded tips and other heating attachments require the head catalyst. Turn the host off, let it cool fully and follow its installation procedure.

The package supplies standard, diagonal and chisel soldering tips, hot knife and hot blower. The host torch is sold separately.

Match the model, attachment and heat requirement before ordering.
| Model or task | Works | What to check |
|---|---|---|
| LX-770 | Listed fit | Use the LX-770 host manual and correct catalyst assembly. |
| LX-771 | Listed fit | Use the LX-771 host manual and correct catalyst assembly. |
| Threaded soldering tips and hot knife | Catalyst required | Confirm your selected package includes the needed assembly parts. |
The set contains standard, diagonal and chisel soldering tips, one hot knife and one hot blower. It does not include the catalyst or deflector supplied with LX-TIP-C.
LX-TIP-D omits the head catalyst. Its threaded tips and hot knife need a serviceable compatible catalyst in the LX-770 or LX-771 host assembly.
A hot knife is supplied separately from the three soldering tips, so the package provides both attachment types. Use the correct material requirements and cool the tool before switching.
No deflector is listed for LX-TIP-D. It includes a hot blower; a complete blower-and-deflector arrangement needs the separate compatible deflector and catalyst.
They are different attachments: three soldering geometries, a blade and a blower. This is not a five-pack of identical standard tips.
LX-TIP-D is listed for the Lexivon LX-770 soldering iron and LX-771 soldering torch. Standalone LX-760, LX-761 and LX-775 are not listed hosts.
No. The diagonal label describes the tip; a verified 3 mm mounting thread is not supplied. Select the named host model rather than buying solely by that tip-width number.
The replacement chisel is listed as 3.5 mm and the hot blower as 4 mm. These labels describe the working attachments, not their mounting thread or a regulated heat setting.
Choose the seven-piece LX-TIP-C if you need a catalyst and deflector together with these five attachments. LX-TIP-D provides five pieces and expects the needed host assembly parts separately.
A catalyst is not in this package. LX-TIP-HC is the catalyst-only option; buying LX-TIP-D does not replace that component.
One standard tip is among the five pieces. The diagonal and chisel add different contact shapes, while the knife and blower have other functions.
No. LX-TIP-D is a five-piece set of soldering attachments. Choose it for replacement heating accessories on LX-770 or LX-771; it supplies no impact sockets.
The replacement set lists a 3 mm diagonal tip and a 3.5 mm chisel tip. These are contact-shape sizes, not mounting-thread measurements.
Lexivon offers the 3 mm diagonal attachment in LX-TIP-D and LX-TIP-C, but no version with the heat exhaust hole relocated. Keep the exhaust clear during use.
No. The blower is a heating attachment, not a regulated control system. The LX-770 and LX-771 manuals describe gas-flow adjustment without a numeric tip-temperature setpoint.
It is a replacement assortment, but it includes four other attachments in addition to the standard tip. LX-TIP-ST is the single-standard-tip option if that is the only piece you need.
No wrenches are identified among the five listed attachments. Use the host kit's specified 7 mm and 8 mm wrenches for threaded parts.
12 months standard; 24 months when you register online within 90 days of purchase. The five-piece set's policy excludes normal wear and misuse; commercial coverage stays at 12 months, and industrial use is excluded.
Support the existing catalyst with the 8 mm wrench and turn the attachment with the 7 mm wrench after full cooling. The manual requires the catalyst to remain in place during threaded-tip work.
Clean the working point and coat it with a thin layer of suitable solder to reduce oxidation. Use good-quality solder matched to the joint.
Count the standard, diagonal and chisel tips, hot knife and hot blower individually. Contact Lexivon about missing listed attachments rather than substituting unknown parts.
Wait for the host and attachments to cool fully, then fit the knife using the threaded-attachment procedure. A different attachment function does not remove the cooling requirement.
Check the original host kit for the compatible deflector. LX-TIP-D supplies the blower only; follow the separate deflector installation in the host manual instead of inventing a substitute.
Appearance after heating alone does not establish a manufacturing defect. The policy covers defects in material and workmanship and excludes normal wear; describe the actual problem to support.
