from your person before doing any welding.  
D
D
Keep your head out of the fumes. Do not breathe the fumes.  
After completion of work, inspect area to ensure it is free of sparks,  
glowing embers, and flames.  
If inside, ventilate the area and/or use local forced ventilation at the  
arc to remove welding fumes and gases.  
Use only correct fuses or circuit breakers. Do not oversize or by-  
pass them.  
D
D
If ventilation is poor, wear an approved air-supplied respirator.  
Read and understand the Material Safety Data Sheets (MSDSs)  
and the manufacturer’s instructions for metals, consumables,  
coatings, cleaners, and degreasers.  
Follow requirements in OSHA 1910.252 (a) (2) (iv) and NFPA 51B  
for hot work and have a fire watcher and extinguisher nearby.  
D
Work in a confined space only if it is well ventilated, or while  
wearing an air-supplied respirator. Always have a trained watch-  
person nearby. Welding fumes and gases can displace air and  
lower the oxygen level causing injury or death. Be sure the breath-  
ing air is safe.  
FLYING METAL or DIRT can injure eyes.  
D
Welding, chipping, wire brushing, and grinding  
cause sparks and flying metal. As welds cool,  
they can throw off slag.  
D
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
Wear approved safety glasses with side  
shields even under your welding helmet.  
Do not weld on coated metals, such as galvanized, lead, or  
cadmiumplated 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.  
BUILDUP OF GAS can injure or kill.  
D
D
Shut off shielding gas supply when not in use.  
Always ventilate confined spaces or use  
approved air-supplied respirator.  
ARC RAYS can burn eyes and skin.  
MAGNETIC FIELDS can affect Implanted  
Medical Devices.  
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
Wearers of Pacemakers and other Implanted  
Medical Devices should keep away.  
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).

Noise from some processes or equipment can  
damagehearing.  
Wear protective clothing made from durable, flame-resistant mate-  
rial (leather, heavy cotton, or wool) and foot protection.  
D
Wear approved ear protection if noise level is  
high.  
WELDING can cause fire or explosion.  
Welding on closed containers, such as tanks,  
drums, or pipes, can cause them to blow up. Sparks  
can fly off from the welding arc. The flying sparks, hot  
workpiece, and hot equipment can cause fires and  
CYLINDERS can explode if damaged.  
Shielding gas cylinders contain gas under high  
pressure. If damaged, a cylinder can explode. Since  
gas cylinders are normally part of the welding  
process, be sure to treat them carefully.  
burns. Accidental contact of electrode to metal objects can cause  
sparks, explosion, overheating, or fire. Check and be sure the area is  
safe before doing any welding.

1-6. EMF Information  
Considerations About Welding And The Effects Of Low Frequency  
Electric And Magnetic Fields  
1. Keep cables close together by twisting or taping them, or using a  
cable cover.  
2. Arrange cables to one side and away from the operator.  
3. Do not coil or drape cables around your body.  
Welding current, as it flows through welding cables, will cause electro-  
magnetic 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 power-  
frequency 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.  
4. Keep welding power source and cables as far away from opera-  
tor as practical.  
5. Connect work clamp to workpiece as close to the weld as possi-  
ble.  
About Implanted Medical Devices:  
ImplantedMedical Device wearers should consult their doctor and the  
device manufacturer before performing or going near arc welding, spot  
welding, gouging, plasma arc cutting, or induction heating operations.  
If cleared by your doctor, then following the above procedures is recom-  
mended.  
To reduce magnetic fields in the workplace, use the following  
procedures:

champs magnétiques et électriques.  
1. Garder les câbles ensemble, les torsader, les scotcher, ou les  
recouvrir d’une housse.  
2. Disposer les câbles d’un côté et à distance de l’opérateur.  
3. Ne pas courber pas et ne pas entourer pas les câbles autour de  
votre corps.  
4. Garder le poste de soudage et les câbles le plus loin possible de  
vous.  
Le courant de soudage, pendant son passage dans les câbles de sou-  
dage, causera des champs électromagnétiques. Il y a eu et il y a encore  
un certain souci à propos de tels champs. Cependant, après avoir exa-  
miné 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  
magnétiqueset 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  
souhaitablede réduire votre exposition aux champs électromagnéti-  
ques pendant le soudage ou le coupage.  
5. Connecter la pince sur la pièce aussi près que possible de la

En ce qui concerne les implants médicaux :  
Les porteurs d’implants doivent d’abord consulter leur médecin avant  
de s’approcher des opérations de soudage à l’arc, de soudage par

tion. Si le médecin approuve, il est recommandé de suivre les  
procédures précédentes.

Failure to follow these electrical service guide recommendations could create an electric shock or fire hazard. These recommenda-  
tions are for a dedicated branch circuit sized for the rated output and duty cycle of the welding power source.  
NOTICE − INCORRECT INPUT POWER can damage this welding power source. This welding power source requires a CONTINUOUS supply of  
input power at rated frequency(+10%) and voltage (+10%). Phase to ground voltage shall not exceed +10% of rated input voltage. Do not use a genera-  
tor with automatic idle device (that idles engine when no load is sensed) to supply input power to this welding power source.  
. Actual input voltage should not exceed 10% of indicated required input voltage. If actual input voltage is outside of this range, output may not  
be available.

5-1. Selecting Weld Cable Sizes*  
ARC WELDING can cause Electromagnetic Interference.  
To reduce possible interference, keep weld cables as short as possible, close together, and down low, such as on the floor.  
Locate welding operation 100 meters from any sensitive electronic equipment. Be sure this welding machine is installed  
and grounded according to this manual. If interference still occurs, the user must take extra measures such as moving  
the welding machine, using shielded cables, using line filters, or shielding the work area.

. In pulse welding applications using inverter power sources, peak currents can result in extreme voltage drops producing poor welding  
characteristics with undersized cables. A recommendation for weld cable size is a minimum of 2/0 for 300 ampere welding power sources and  
4/0 for 450 ampere welding power sources when total cable length is less than 100 ft (30m).

The electrode sense lead is contained  
in the feeder control cable and  
automatically becomes enabled for all  
semi-automatic processes. The work  
sense lead connects to the Axcess  
welding power source 4-pin connector  
located above the negative output  
terminal. This work sense lead  
automatically compensates for work  
cable voltage drop when connected to  
the welding power source.

Do not coil excess cables. Use cables  
that are the appropriate length for the  
application.Whenever using long weld  
cables [longer than 50 ft (15 m)] try to  
arrange positive and negative weld  
cables together to reduce the magnetic  
field surrounding the cables. Avoid  
coupling the feeder and work sense  
leads with the weld cables.

work cables together at the workpiece.  
This is very important for pulse welding  
applications.

It is important to connect the voltage  
sensing lead as near to the weld as  
possible, but not in the return current  
path.  
Connect voltage sensing lead at the end  
of the weld joint.  
The direction of the welding path should  
be away from the work cable  
connections.

Connect work clamp at the beginning of  
the weld joint.

Each welding gun should have its own  
source of shielding gas. Use a separate  
shielding gas regulator and shielding  
gas connection for each welding gun.

Arc blow is the deflection of a welding  
arc from its normal path due to magnetic  
forces. It will adversely affect the  
appearanceof a weld, cause excessive  
spatter, and impair the quality of a weld.  
Arc blow occurs primarily during the  
welding of steel or ferromagnetic  
metals.Weld current will take the path of  
least resistance, but not always the  
most direct path through the workpiece  
to the work lead connection. The most  
intense magnet force will be around the  
arc due to a difference in resistance for  
the magnetic path in the base metal.  
The work clamp connection is important  
and should be placed at the starting  
point of a weld. It is recommended to  
have as short of an arc as possible so  
that there is less of an arc for the  
magnetic forces to control. Conditions  
affecting the magnetic force acting on  
the arc vary so widely that the reference  
here is only about cabling connections  
and arc preferences.

Considerations About Welding And The Effects Of Low Frequency  
Electric And Magnetic Fields  
1. Keep cables close together by twisting or taping them, or using a  
cable cover.  
2. Arrange cables to one side and away from the operator.  
3. Do not coil or drape cables around your body.  
Welding current, as it flows through welding cables, will cause electro-  
magnetic 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 power-  
frequency 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.  
4. Keep welding power source and cables as far away from opera-  
tor as practical.  
5. Connect work clamp to workpiece as close to the weld as possi-  
ble.  
About Implanted Medical Devices:  
ImplantedMedical Device wearers should consult their doctor and the  
device manufacturer before performing or going near arc welding, spot  
welding, gouging, plasma arc cutting, or induction heating operations.  
If cleared by your doctor, then following the above procedures is recom-  
mended.  
To reduce magnetic fields in the workplace, use the following  
procedures:
