When operating a welder, certain precautions must
be taken to prevent minor injuries to yourself and
others. Although injuries may not be serious or per-
manent, knowing how to use the protective equip-
ment to safeguard against them is the first step in
learning to weld.

The effects of heat and light given off by the arc, whde
electric welding, may be compared to that of the sun's rays.
Even greater precautions are necessary for electric arc
welding. Before starting a weld, caution anyone in the
immediate vicinity against looking at the arc. In case of
accidental eye iniury, contact a physician immediately
To protect the face and eyes a heat-resisting, hbreglass
helmet is used. The special lens, which allows the user
to view the arc safely, is inserted rata the framed opening
of the helmet The dear glass, which should be replaced
from t_me to t_me, protects the expensive special lens
from breakage and weld spatter. The _elmet is held firmly
_n place on the head with an adjustable head band, thereby
leaving both hands free. A close-fittlng skuff cap should
be worn w_th the helmet. As the he)met _sused only when
actually welding, a t_ltmg arrangement permits _t to be
swung up clear of the face. When the welding _sresumed
a s|ight nad of the head tips the helmet down over the Face.
To protect the eyes further wh_le cleaning the weld, goggles
should be worn by the welder and others working around
him. Animals are also affected by the rays and should be
kept at a safe distance.
To safeguard the hands against heat and weld spatter,
gauntlet-type leather gloves s_ould be worn. A leather
jacket will give beiCer protection against the shower of
sparks than ordinary clothing. H_gh top shoes (not oxfords)
should be worn. If a great deal of welding is to be done,
foundrymen's shoes are best.
Precautions must also be taken to protect property and
equipment against fire. A large fire extinguisher shouTdbe
within easy reach. The we_ding area should have a concrete
or cinder floor, kept dry and dear of inflammable rubbish.
Sometimes, it _s necessary to weld close to a fuel tank. If
practical, remove the part to be welded If not, dram the
tank and completely fill it w_th water.
Few tools, in addition to those supplied w_th the welding
machine, are needed and most of them can be found in
the average shop Two sawhorses supporting a 1/4-inch
steel plate makes an excellent welding table A permanent
bench, using the same steel plate, can be made of angle
iron or p_pe. A ch_pping hammer is used to clean slag off
a weld and phers will be useful for handling hot metak A
w_re brush _sused to dean the work before welding and
remove small pieces of slag after chipping.
Small pieces of todd-steel scrap iron, reasonably free of
rust and paint, should be used for prachce welding. Angle
iron, bar stock or plate steel are good examples. Do not
_sse scrap cast iron, high carbon or hardened steel as these
rneta|s require special electrodes and welding techniques.
These should be set aside for future practice after com-
pleting elementary practice lessons
