Weller PTA7 Soldering Iron Chisel Tip 0.063 in

Product Description

The WELLER PTA7 is a chisel-style replacement soldering tip designed for use with Weller PT-series soldering stations. The tip measures 1.299 inches in length with a point width of 0.063 inches, making it well suited for through-hole soldering, drag soldering, and general-purpose rework tasks where a flat, broad contact surface improves heat transfer to pads and leads. Electricians, electronics technicians, and HVAC controls specialists routinely use chisel tips for production and service work where flat joints and consistent thermal contact are priorities. The PTA7 is a direct drop-in replacement that requires no modification to the iron handle.

The PTA7 is intended for bench and field soldering applications in residential and light commercial electrical or HVAC controls work. It performs well on standard rosin-core and no-clean solder alloys used in low-voltage control wiring, circuit board rework, and connector termination. The chisel geometry provides a larger contact footprint than a conical tip, which speeds up joint completion on multi-pin connectors, terminal strips, and PCB pads found in control boards and sensor assemblies.

Key Features

• Chisel tip geometry for improved heat transfer to flat pads and wire leads
• Point width of 0.063 inches suits both fine and medium-pitch soldering work
• Tip length of 1.299 inches for standard reach in confined control panel spaces
• Part of the PT series, compatible with Weller PT-series soldering stations
• Lightweight at 0.03 pounds for reduced hand fatigue during extended use

Compatibility

Designed for use with Weller PT-series soldering stations as specified by the manufacturer. Verify station model compatibility before ordering to confirm correct tip fit and thermal interface.

Installation Notes

Soldering tip replacement is performed by electrical and electronics technicians following the iron manufacturer's tip-change procedure. Always allow the soldering station to cool completely and power it off before removing or installing a tip to prevent burns and tip damage. Tin the new tip with fresh solder immediately upon first heat-up to establish a protective coating and extend tip life. Follow applicable workplace safety guidelines for soldering fume ventilation and ESD precautions when working on sensitive control boards.
