Weller PT A7 soldering tip (4PTA7-1)
The Weller PT A7 (Item No. 4PTA7-1) is a chisel-style soldering tip designed for the Weller Magnastat system. The description and manufacturer data specify the tip type, dimensions, and nominal operating temperature as specified by Weller.»
Product Overview
- Product name: Weller PT A7 (Item No. 4PTA7-1)
- Tip shape: Chisel
- Tip type: HM
Typical Applications
The only direct application specified in the manufacturer's documentation is as a replaceable, temperature-sensitive soldering tip for the Weller Magnastat system. Specifically, the Weller PT A7 is used as a tip with built-in temperature sensing, where the operating temperature is selected by switching to a tip with the desired temperature rating.
Technical Note
The Magnastat system operates using a ferromagnetic sensor element in the tip, which changes characteristics at specific temperatures. This causes a permanent magnet to either attract or repel, thereby controlling the power supply's switch. The system allows for quick on/off of the heating element and selection of predetermined tip temperatures by replacing the temperature-sensitive tip.
