ELECTRIC SHOCK can kill.
Touching live electrical parts can cause fatal shocks
or severe burns. The electrode and work circuit is
electrically live whenever the output is on. The input
live when power is on. In semiautomatic or automatic wire welding, the
wire, wire reel, drive roll housing, and all metal parts touching the
welding wire are electrically live. Incorrectly installed or improperly
grounded equipment is a hazard.
D Do not touch live electrical parts.
D Wear dry, hole-free insulating gloves and body protection.
D Insulate yourself from work and ground using dry insulating mats
or covers big enough to prevent any physical contact with the work
or ground.
D Do not use AC output in damp areas, if movement is confined, or if
there is a danger of falling.
D Use AC output ONLY if required for the welding process.
D If AC output is required, use remote output control if present on
unit.
D Additional safety precautions are required when any of the follow-
ing electrically hazardous conditions are present: in damp
locations or while wearing wet clothing; on metal structures such
as floors, gratings, or scaffolds; when in cramped positions such
as sitting, kneeling, or lying; or when there is a high risk of unavoidable or accidental contact with the workpiece or ground. For these
conditions, use the following equipment in order presented: 1) a
semiautomatic DC constant voltage (wire) welder, 2) a DC manual
(stick) welder, or 3) an AC welder with reduced open-circuit voltage. In most situations, use of a DC, constant voltage wire welder
is recommended. And, do not work alone!

D Turn Off inverter, disconnect input power, and discharge input
capacitors according to instructions in Maintenance Section
before touching any parts.
FUMES AND GASES can be hazardous.
Welding produces fumes and gases. Breathing
these fumes and gases can be hazardous to your
health.
D Keep your head out of the fumes. Do not breathe the fumes.
D If inside, ventilate the area and/or use local forced ventilation at the
arc to remove welding fumes and gases.
D If ventilation is poor, wear an approved air-supplied respirator.
D Read and understand the Material Safety Data Sheets (MSDSs)
and the manufacturer’s instructions for metals, consumables,
coatings, cleaners, and degreasers.
D Work in a confined space only if it is well ventilated, or while
wearing an air-supplied respirator. Always have a trained watchperson nearby. Welding fumes and gases can displace air and
lower the oxygen level causing injury or death. Be sure the breathing air is safe.
D Do not weld in locations near degreasing, cleaning, or spraying op-
erations. The heat and rays of the arc can react with vapors to form
highly toxic and irritating gases.
D Do not weld on coated metals, such as galvanized, lead, or
cadmium plated steel, unless the coating is removed from the weld
area, the area is well ventilated, and while wearing an air-supplied
respirator. The coatings and any metals containing these elements
can give off toxic fumes if welded.

ARC RAYS can burn eyes and skin.
BUILDUP OF GAS can injure or kill.
Arc rays from the welding process produce intense
visible and invisible (ultraviolet and infrared) rays
that can burn eyes and skin. Sparks fly off from the
weld.
D Wear an approved welding helmet fitted with a proper shade of fil-
ter lenses to protect your face and eyes when welding or watching
(see ANSI Z49.1 and Z87.1 listed in Safety Standards).
D Wear approved safety glasses with side shields under your
helmet.

1-6.EMF Information
Considerations About Welding And The Effects Of Low Frequency
Electric And Magnetic Fields
Welding current, as it flows through welding cables, will cause electromagnetic fields. There has been and still is some concern about such
fields. However, after examining more than 500 studies spanning 17
years of research, a special blue ribbon committee of the National
Research Council concluded that: “The body of evidence, in the
committee’s judgment, has not demonstrated that exposure to powerfrequency electric and magnetic fields is a human-health hazard.”
However, studies are still going forth and evidence continues to be
examined. Until the final conclusions of the research are reached, you
may wish to minimize your exposure to electromagnetic fields when
welding or cutting.
To reduce magnetic fields in the workplace, use the following
procedures:

Considérations sur le soudage et les effets de basse fréquence et des
champs magnétiques et électriques.
Le courant de soudage, pendant son passage dans les câbles de soudage, causera des champs électromagnétiques. Il y a eu et il y a encore un
certain souci à propos de tels champs. Cependant, après avoir examiné
plus de 500 études qui ont été faites pendant une période de recherche
de 17 ans, un comité spécial ruban bleu du National Research Council a
conclu : « L’accumulation de preuves, suivant le jugement du comité, n’a
pas démontré que l’exposition aux champs magnétiques et champs électriques à haute fréquence représente un risque à la santé humaine ».
Toutefois, des études sont toujours en cours et les preuves continuent à
être examinées. En attendant que les conclusions finales de la recherche
soient établies, il vous serait souhaitable de réduire votre exposition aux
champs électromagnétiques pendant le soudage ou le coupage.
Pour réduire les champs magnétiques sur le poste de travail, appliquer

3-3.Duty Cycle And Overheating
For Each Module And Total System
60% Duty Cycle At 200 Amperes
6 Minutes Welding4 Minutes Resting
For Main Transformer
The main transformer of the polyweld system has dual duty cycle ratings, each for
a specific amperage output range. If the unit is operated in the 800 ampere range,
the unit is rated at 100% duty cycle. This means the polyweld system can be operated at 800 amperes continuously. When the unit is operated in the 1600 ampere
range, it is rated at 25% duty cycle.
Duty Cycle is percentage of 10 minutes that unit can weld at rated load
without overheating.
If unit overheats, thermostat(s)
opens, output stops, and cooling
fan runs. Wait fifteen minutes for
unit to cool. Reduce amperage or
duty cycle before welding.
Y Exceeding duty cycle can
damage unit and void
warranty.
The sum of the outputs of each module should not exceed the rated duty cycle of
the main transformer. For example, the polyweld system can be safely operated at
a load of 1000 amperes at 60 percent duty cycle. This value could be obtained by
operating five modules at a load of 200 amperes at 60 percent duty cycle, or by
operating eight modules at a load of 125 amperes at 60 percent duty cycle.
Overheating
Thermostat TP1 protects the polyweld system. If main transformer T1 gets too hot,
TP1 opens and weld output stops. The stabilizer in each of the eight modules is protected from overheating by thermostat TPX1 (“X” represents the number of the
applicable module, 1−8). If overheating of a stabilizer occurs, the associated ther-
mostat opens, reducing weld output to a minimum that cannot be regulated. The
fans keep running to cool the stabilizer. Wait several minutes before trying to weld.

1 Overload Supplementary
Protecotr CB1
Supplementary protector CB1 protects the 115 volts ac windings of
control transformer T3 from overload. If CB1 opens, the 115 volts ac
duplex receptacle RC2 would not
work. Manually reset CB1.
2 Module Supplementary
Protectors CB11 Through
CB81
The control circuitry in each of the
eight modules is protected from
overload by a supplementary protector CBX1 (“X” represents the
number of the applicable module,
1−8). If a module supplementary
protector opens, output from the
affected module would drop to minimum and can not be regulated.
Manually reset the affected
protector.
