Axe-type soldering irons

 

— soldering irons with a large flat tip in the form of a wedge attached to a handle made of heat-resistant material in the image and likeness of an ax handle. The wide tip creates a large area of contact between the mating parts for efficient heat transfer and a strong bond. Soldering hatchets are used in tin work: when repairing dishes, soldering leaky barrels, heating radiators, etc.
