Weller PTM7 (370°C) 3.2 mm Screwdriver Soldering Iron Tip, PT Series, for TCP Series (Old Generation)

The Weller PTM7 (370°C) 3.2 mm Screwdriver Soldering Iron Tip is a precisely engineered accessory developed for older TCP series (old generation) soldering irons. As part of the renowned PT tip series, it offers users a reliable solution for demanding hand soldering applications in professional electronics and industrial assembly environments.

This replacement tip presents a broad 3.2 mm screwdriver-style contact surface, purposefully tailored for operations that demand extensive joint wetting, such as when working with large pads or heavy-gauge component leads. The wide, flat tip concentrates high thermal energy, which ensures effective solder flow and even heat distribution, helping to produce robust solder joints on both through-hole and surface mount technology assemblies.

Rated for stable operation at 370°C, the PTM7 tip supports lead-free as well as conventional solder processes. Its consistent thermal response minimizes downtime between soldering cycles and allows operators to maintain productivity during assembly, rework, or maintenance. Its robust construction permits repetitive fitting and detachment, while maintaining correct seating and thermal contact with TCP legacy connectors - ensuring mechanical and electrical compatibility every time the tip is changed.

The screwdriver shape is particularly advantageous for applications requiring broad wetted areas, helping to avoid solder bridging and delivering high-quality results on wide joints. Broad coverage allows efficient soldering and rework on boards where larger copper pads or higher heat-sink mass is present, such as industrial, laboratory, and manufacturing assembly lines.

This tip is an essential consumable for those who rely on older-generation TCP soldering irons for everyday tasks, from industrial electronics repair and production soldering, to maintenance and assembly in commercial service shops. By preserving the established TCP interface, it allows organizations with installed legacy equipment to extend their tool investment and maintain consistent workflow without compromising on tip performance or compatibility.

For optimal results, users should confirm that their soldering iron uses the compatible TCP legacy connection, and observe standard handling precautions when working at high operating temperatures. Routine replacement of worn tips ensures the soldering station delivers repeatable performance and minimizes the risk of cold joints or insufficient solder spread.
