SAFETY gNSTRUCTIONS TO OPERATOR
For your own protection, read and observe all instructions
included in this manual as well as the following specific
safety precautions:
1, PROTECTION FROM ELECTRICAL SHOCK
a_ Do not let bare skin or wet clothing come between
the following combinations:
Work Clamp
Electrode
Work Piece Metal Work 'Table
80 volts exist between these parts
when welder isonH!
Wear dry hole-free, clothing,_ gloves and shoes to
protect and insulate the body.
b. Take special care to insulate"yourself from ground
using dry insulation (suchas dry wood) of-ad.equate
size when welding] in dam'p locations on metal floors
or grat ngs, and m poslt_ons (such as s=ttmg or lying ! "
where parts-or"large"areas of your body can be ir
contact with phssible ground_. ; ".;_ ro "_

condition, : _ _; " " ,:' -' • "
Do not use weldm_ electrode as-aclaarette hg_ter, . -
e. Connect the welder only to a source of electncal'.-
power meeting the requirements, irrcluding
grounding, of the National Electrical Code (ANSI Cl)
and local codes.
f. Electrode coating may be electrically conductive-
use welding gloves when changing electrodes.
2. EYE AND BODY PROTECTION
a. Use helmet, filter, and cover plate complying with
ANSI Z87 1 to protect your eyes and face from
sparks and the rays of the arc when welding or
observing open arc welding,
b Always wear safety goggles with side shields
complying with ANSI Z871 when in a welding area,
or when near slag chipping operation
c. Wear oil free protective garments, such as leather
gloves, heavy shirt, cuffless trousers and high shoes.
d Protect other near-by personnel with suitable
non-flammable screening_
e
Welding can produce fumes and gases which are
dangerous to health, Keep your head out of the
fumes, Use enough ventilation, exhaust at the arc, or
both, to keep fumes and gases from your breathing
zone and the general area, Take even greater care
when welding on galvanized or cadmium plated steel
and other metals which produce toxic fumes
Ab-supplied helmets may be necessary
f When working above floor level, protect yourself
from a fall should you get a shock Never wrap the
electrode cable around arty part of your body
g Do not weld in locations close to chlorinated
hydrocarbon vapors coming from degreasing,
cleaning, or spraying operations The heat of the rays
of the arc can react with solvent vapors to form
phosgene, a highly toxic gas, and other irritating
products
h Unprotected spectators must be kept clear of the
welding area due to the harmful nature of ultra÷violet
and infra-red arc rays, welding sparks, and welding
fumes and gases
3. FLAMMABLE AND EXPLOSIVE MATERIALS
a Remove flammable and explosive material at least 35
feet from the welding arc to prevent welding sparks
or molten metal from starting a fire Keep a type
ABC fire extinguisher within easy reach.
b, Welding on or near containers which hold combustibles
can cause ar_explosion, even when they have been
cleaned= For information purchase "Safe Practices for
Welding one Cutting Containers that Have Hel d
Combustibles" (A6.0-65_ from the American Welding
:.Society 2501 Northwest Seventh St Miami, Florida
c. When not welding, place the electrode holder where it
"" i_ ihs'61ated from the work clamp, work piece, or'
wc_rk 'table_._ Ac_'idental grounding can cause
,_ overheating of the_ables'and_welder, creating a fire
haz_rd_ _ ::_" _ "

b_ _'he'worl<:p e_e o_ me.to _ork tab e Conr]ecting
to other objects such as bu_l_mg ground can create a
fire hazard.
4. PREVENTATIVE MAINTENANCE
a. Never apply power to the welder with any part of the
"cabinet" removed_ Position on-off switch in "Off"
position and disconnect welder from the power
supply before doing maintenance work inside the
machine. Removal of the welder cabinet should be
done only by a qualified service technician,
b.
c.
d_
Before connecting the welder power cord to the
receptacle, check the following:
1 Inspect the power cord and welding cables for cuts
or burns and make sure blades and ground pin on
the plug are straighL
2 Inspect "On-Off" switch lever for cracks or broken
parts.
3 Inspect electrode holder jaw insulators for cracks
or broken parts.
Never weld anything on or to the welder cabinet, as a
burn through may cause transformer failure.
For additional safety information, purchase copies of
"Practice for Occupational and Educational Eye and
Face Protection" (ANSI Z87.1), "Safety in Welding
and Cutting" (ANSI Z49.1), and "Fire Protection in
Use of Welding and Cutting Processes" (ANSI/NFPA
No. 518) from the American National Standards
institute, 1430 Sroadway, New York, N.Y 10018_
