Weller WPA2 Pyropen Soldering Iron Review

Weller Pyropen
Weller Pyropen

The Weller WPA2 Pyropen Professional Self-Igniting Cordless Butane Soldering Iron is a versatile solder gun ideal for soldering in awkward or remote places. This makes it perfect for field work because no batteries, cords, or power are required for it to operate. It runs on butane, which you can purchase separately.

The Weller butane soldering iron is very lightweight, which enhances its portability, but the tank holds enough butane gas to last for approximately three hours. Even better is the time it takes to be ready to use; while 30 seconds is the stipulated time, customers have found that the soldering tip is hot almost immediately.
