SOLDERING TIN CANS
Use Of Soldering Irons and Flux. Op.
eratiOns Described in Detail.

With the growth of canning clubs
has come greater demand for the
knowledge of how to handle soldering
outfits for the sealing of tin cans. In
some parts of the country tin cans
are used quite generally by farmers
for canning surplus fruits and veget-
ables. The same fundamental princi-
pies are applied to soldering fruit and
vegetable cans as are used in any
other soldering operation. The type
of can to be preferred is the one sup
piled with cap already equipped
with rim of solder The cans are
known to the trade as packers cans.
The ordinary outfit for soldering
the caps on tin cans and making them
air tight consists of:
A Gaping iron, used to melt the SOL
der on the solder-hemmed cap and
unite it with the can top.
Tipping copper, commonly known
as a soldering iron, used for melting
and applying solder to the small vent
hole in the center of the cap and to
leaks.
A small brush, porcelain, glass
or crockery cup, something that can
not be used for a drinking cup (never
allow flux cup to stand where little
children can reach it, In which to
keep flux; sal ammoniac; few
scraps of zinc; muriatic acid a soft
brick or piece of soft limestone; and
a small supply of soldering lead.
Soldering flux is solution of zinc
in crude muriatic acid and is used fol-
brushing the tin and solder surfaces
so the solder in It's melting condition
will adhere to the tin.
To make the flux, purchase at The
drug store about 10 cents worth Of
crude muriatic acid and place this ir
porcelain, crockery or glass jar
Such par of cup is used rather thar
metal as the acid would usually at
tack or eat the metal. Add as mucl
sheet zinc in small pieces as the acit
will thoroughly dissolve. Before thu
flux is used, let it stand 10 to II
hours. Dilute with water half ant
half and strain the flux through ;
piece of cloth or muslin. Be careful
not to spill this acid flux on tn
clothing and always keep 1t out o
the reach Of children. When usinl
the soldering flux, keep it well mixe'
and always free from dust and dirt
Provided one does not care to max
the soldering flux, it can usually b
purchased at drug or hardware stores
Thinning the Gaping and Tipping Iron
The tipping copper or Gaping irol
may be cleaned of smudge, burne
material, ETC., by securing it on
soft brick, piece of sandstone, sand
!. paper, or it may have to be filed
rusty. A mixture Of sal ammonia
and solder is used for timing tn
Gaping iron and tipping copper an
to put a bright, smooth surface O.
them A few pieces of solder ar
melted with the soldering iron into
or 10 cents worth of sal amonnia
which can be purchased at the dru
store. The clean Gaping iron is heat
ed until almost red hot. Then dip
quickly into the flux and then thrus
into the box containing the sal am
moniac and solder. 1t will CONVEX
the solder into a liquid and thus cos
or tin the iron so the solder will flo,
evenly when sealing the cans. Rotat
It in the mixture until the solderin
edge OF the iron has become brigh
and thoroughly covered with solder
Again dip 1t in the flux. The tippin
copper is timed Covered with solder
very much the same as the cappin
