Soldering tips

The Weller RTM series provides micro soldering tips for the WXMP and WMRP irons, designed for precision work on fine SMD components. The range covers conical tips from 0.1 mm (RTM 001 C NW) through chisel geometries from 0.2x0.1 mm up to 3.6x0.9 mm, including bent 30° variants (RTM 008 S X) and the solder depot tip RTM 020 G (1.2x2 mm). Tips marked "NW" are chrome-plated and non-wettable, intended for repositioning 0201 and 0402 components without transferring solder.

⚙ Conical (C), from 0.1 mm - RTM 001 C to RTM 008 C for spot soldering and wire terminations

⚙ Chisel (S), 0.2x0.1-3.6x0.9 mm - widest geometry selection, also bent 30° (RTM 008 S X, RTM 013 Sx)

⚙ Round bevel (B), D: 0.4-1.2 mm - RTM 004 B, RTM 012 B for pad soldering

⚙ Knife (K), 2.2 mm - RTM 030 K, 45° bevel, for bridging corrections

✓ Solder depot (G), 1.2x2 mm - RTM 020 G for stencil soldering and defined solder volumes

✓ NW variants chrome-plated, non-wettable - RTM 001 C NW, RTM 003 S NW for 0201/0204 parts without solder transfer

Type	Geometry	Dimension	Note
RTM 002 C	Conical	0.2 mm	Standard tip
RTM 008 S X	Chisel bent 30°	0.8x0.4 mm	Hard-to-reach areas
RTM 020 G	Solder depot	1.2x2 mm	Defined solder volume
RTM 001 C NW	Conical, non-wettable	0.1 mm	0201/0204 components
RTM 028 X	Measurement tip	-	Temperature measurement WXMP/WMRP
RTM 036 S	Chisel	3.6x0.9 mm	Largest chisel in series

All RTM tips are compatible with the WXMP and WMRP soldering irons. The RT-1SC03 tip (0.3x0.15 mm chisel) belongs to the RT series and is also listed in this category.

Typical applications: Rework and repair of SMD components (0201, 0402, 0603), precision soldering on mobile devices, watch electronics and sensors, placement corrections in PCB assembly, and work requiring controlled solder volumes on ICs and fine-pitch components. The 30° bent variants enable access in congested areas on densely populated boards.
