1.2 Safety Concerns
Safety should be one of the utmost concerns for
each user of a Nelweld unit. Knowledge of and
careful attention to all safety advice granted in
this manual is highly advised by Nelson Stud
Welding, Inc.
Observing all safety warnings and advice is a
prerequisite for safe and correct handling and
trouble-free operation of the Nelweld series of
stud welding power supplies.
1.2.1 Safety Advice
Operating instructions must always be kept at the
place the Nelweld unit is used. The ability to
quickly
consult
the
manual
is
highly
recommended to all Nelweld users.
Safety signs, stickers, etc. must remain attached
to the Nelweld unit at all times. They should
remain free from dirt and be kept in legible
condition.
1.2.2 Personnel Training
All operating personnel of the Nelweld power
supply series must:
•
Be instructed in handling welding appliances,
•
Have had training and possess authorization
to perform stud welding,
•
Know and follow the contents of this
operations manual.
All electrical repair personnel must:
•
Have had training that qualifies them to carry
out repairs on the Nelweld unit,
•
Be entitled to operate electrical circuits and
appliances
in
accordance
with
safety
engineering standards.
Apprentices, or personnel receiving on-the-job
training, must:
•
Work with the welding system
only
under the
supervision of an experienced specialist,
•
Know and follow the contents of this
operations manual.
1.2.3 Personal Protection Equipment
Wearing proper protective equipment is a
mandatory stipulation for all operating personnel,
apprentices, and trainees. This includes the use
of:
•
Oil-free, protective garments covering the
entire body, such as leather gloves, heavy
shirt, cuffless trousers, high shoes, and a cap
over your hair (for downhand and vertical
welding),
•
Welder’s protective glasses with a protective
filter,
•
Helmet, when welding overhead,
•
Ear protection is recommended, but not
required.
•
During welding, exposed metallic parts of the
weld gun, such as the stud, chuck, and all
parts electrically connected to these parts, are
current-carrying. To reduce the risk of
accidental
electrocution,
do
not
wear
conductive jewelry, like rings, watches, or
chains.
1.2.4 Protective Measures at the Worksite
The workplace must be of such a nature that
people in the vicinity are adequately protected
from the harmful effects of optical radiation and
generated heat. Space limiters and protective
screens must be placed in such a way that the
reflection and permeability of any radiation are
avoided as much as possible.
Combustible and flammable materials must be
removed from the welding zone. A guarantee
must be given that a fire extinguisher is on hand
on the premise, and within easy reach of the
operator. Only weld in areas or rooms where
adequate ventilation of weld gases is possible,
and where there are no fire, smoke, or explosion
hazards. In the event that such a location cannot
be used or such conditions cannot be avoided,
consult an authorized welding supervisor or fire
safety officer
prior to
welding.
Ensure that the workspace is adequately lit.
