So much welding is done now, and so many people know of its
advantages, that every repair shop of any size should have a weld-
ing outfit. A frame job is essentially an inside bench job, but a
large number of cases of welding could be done directly on the car
outside the building, particularly in summer when the outside air
and cooling breezes are desirable. So, it is well to construct a small
truck on which to keep the
oxygen tank, acetylene cylin-
der, nozzle for working, and a
fire extinguisher. One form
of a truck is shown in Fig.
390. This truck is a simple
rectangular platform with
casters, a handle, and a rack
to hold the tanks. It saves
many steps and is particu-
larly convenient in summer
months. This outfit is essen-
dally a home-made affair, but ,v ,™, „ ^ „ . ., ^ .=.

the gas-welding and electric-
welding manufacturing companies have designed small outfits espe-
cially for automobile repair work, which would be preferable to the one
in Fig. 390, especially where the amount of repair work warrants a
reasonable expenditure for a welding outfit. A description of both gas
and electric outfits and instructions for their use are given in the
section on Oxy-acetylene Welding Practice.
