Sol′der-ing-tool.
The soldering-tool, generally termed a
soldering-iron, used by tinmen and other workers in thin sheet-metals, consists of a copper
bit or
bolt having a pointed or wedge-shaped end, fastened to an iron rod with a wooden handle.
It is
tinned previous to being used by heating to a dull red, hastily filing off the scale, so as to produce a clean metallic surface, and then rubbing, first upon a lump of sal-ammoniac and next upon a copper or tin plate on which a few drops of solder have been placed, and afterward wiped clean with tow. Various improved forms have been contrived.

In
Fig. 5299, the body
A is made of cast-iron and has a dovetail mortise at the end, into which a tenon on the copper point
B is expanded by driving.
Another has a copper point cast on to the iron body.

In another (
Fig. 5300), the bit is reversible, and may be protruded any desired distance beyond the socket in which it is held, the rod to which the handle is attached being screwthreaded and working through the socket.

In
Sears' (
Fig. 5301), the copper tip
a is hollow at the base and receives the hollow handle
b, which is screwed therein, and is connected by a flexible pipe
c with a nozzle through which two pipes provided with cocks
d d′ project respectively air and gas. The gas is first let on, and as it escapes at the base of a is lighted, and the air-supply cock being then opened, a flame is maintained at the aperture in the handle
b, near the end of the tip
a, at the point where the greatest heat is required, its intensity being regulated by means of the cocks
d d′. A shield
e on the handle serves to deflect the heat back on the tip
a and protect the hand of the operator.
When not in use, the tip is inserted in the hollow rest
f.
