Iroda S-52 | 2.4 mm Chisel Soldering Tip | Fits Iroda Pro-80 and Pro-90 Models

Iroda S-52 is a 2.4 mm chisel soldering tip designed for the Iroda/Pro-Iroda SolderPro 80 and SolderPro 90 (including 90K kit) series of cordless butane soldering irons.

Key Specifications

• Tip style: Chisel / screwdriver
• Working edge: Ø 2.4 mm (top)
• Overall length: Approximately 24.5 mm
• Base/bottom diameter: Ø 9.8 mm (threads into the iron’s tip housing via the standard locking nut)
• Operating temperature (on compatible irons): Approximately 752 °F (400 °C)
• Equivalent power range of the host tools: 25–80 W

It is the standard chisel tip in the SolderPro 90K kit and is also used on the SolderPro 80.

Design and Construction

The S-52 is a catalytic soldering tip typical of Iroda’s butane tools. It contains a delicate internal catalyst that converts the butane/air mixture into flameless heat at the tip. The body is generally copper-based with an iron plating (or similar high-conductivity, oxidation-resistant coating) for strong thermal transfer and durability under repeated heating cycles.

The chisel face gives a broader contact area than the S-51 conical tip, so it holds more solder and transfers heat more efficiently into wires, terminals, and larger joints. Like other tips in the series, it uses a quick-change design: the entire tip assembly unscrews via a knurled nut. Always allow the tip to cool fully before changing it, and avoid overtightening or mechanical shock, as the internal catalyst is fragile.

Compatibility

Primarily for:

• Iroda SolderPro 90 / 90K
• Iroda SolderPro 80 / 80K

It is not interchangeable with the S-12/S-13 chisel tips used on the smaller Pro-50/Pro-70 series, or with the PS-series chisels used on Pro-100/110/120/150 tools. The Ø 9.8 mm base and overall form factor are specific to the 80/90 platform.

Typical Applications

The 2.4 mm chisel face is optimized for general-purpose soldering where contact area and heat transfer matter more than a needle-fine point:

• Wire tinning, splices, and terminal connections
• Automotive, marine, and appliance wiring
• Medium electronics joints and connectors
• Audio, lighting, and small-engine electrical work
• Hobby, craft, and field repairs where a conical tip is too small

It is less ideal for very tight PCB pads or ultra-fine component work (for those, the companion S-51 1 mm conical tip is preferred).

Performance Notes

On the SolderPro 90, the tip reaches working temperature in about 17 seconds. Heat output is adjustable via the iron’s gas control lever (mid-setting is typically recommended for soldering). Runtime of the iron itself is up to about 53 minutes per fill on mid setting, depending on gas quality and conditions.

Proper care significantly extends tip life:

• Tin the flat face regularly while hot.
• Clean with a damp sponge or brass wool (avoid aggressive abrasion).
• Do not run the tip dry for extended periods or subject it to mechanical impact.
• Use quality rosin-core solder.

Related Tips in the Same Series

The SolderPro 80/90 platform uses the S-5x family:

• S-51 — 1 mm conical (precision soldering)
• S-52 — 2.4 mm chisel
• S-53 — Hot-knife (45°)
• S-54 — Hot-air blower

These share the same Ø 9.8 mm base for quick interchangeability.

In short, the Iroda S-52 is a genuine OEM chisel tip that delivers broader contact and stronger heat transfer for wiring and general soldering on the compact SolderPro 80 and 90 butane irons. It is a consumable part intended as a direct replacement or spare for the chisel tip supplied with those tools.
