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

single weld output terminal.
SIGNIFICANT DC VOLTAGE exists after removal of
input power on inverters.
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 exhaust at the arc to remove
welding fumes and gases.
D If ventilation is poor, use an approved air-supplied respirator.
D Read 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 th e 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 if necessary, while wearing an
air-supplied respirator. The coatings and any metals containing
these elements can give off toxic fumes if welded.
OM-359 Page 1
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 a welding helmet fitted with a proper shade of filter 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.
D Use protective screens or barriers to protect others from flash and
glare; warn others not to watch the arc.
D Wear protective clothing made from durable, flame-resistant mate-
rial (leather and wool) and foot protection.
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
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.
D Protect yourself and others from flying sparks and hot metal.
D Do not weld where flying sparks can strike flammable material.
D Remove all flammables within 35 ft (10.7 m) of the welding arc. If
this is not possible, tightly cover them with approved covers.
D Be alert that welding sparks and hot materials from welding can
easily go through small cracks and openings to adjacent areas.
D Watch for fire, and keep a fire extinguisher nearby.
D Be aware that welding on a ceiling, floor, bulkhead, or partition can
cause fire on the hidden side.
D Do not weld on closed containers such as tanks, drums, or pipes,
unless they are properly prepared according to AWS F4.1 (see
Safety Standards).
D Connect work cable to the work as close to the welding area as
practical to prevent welding current from traveling long, possibly
unknown paths and causing electric shock and fire hazards.
D Do not use welder to thaw frozen pipes.
D Remove stick electrode from holder or cut off welding wire at
contact tip when not in use.
D Wear oil-free protective garments such as leather gloves, heavy
shirt, cuffless trousers, high shoes, and a cap.

1-5.EMF Information
Considerations About Welding And The Effects Of Low Frequency
Electric And Ma g netic 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 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.
To reduce magnetic fields in the workplace, use the following
procedures:
1. Keep cables close together by twisting or taping them.
2. Arrange cables to one side and away from the operator.
3. Do not coil or drape cables around your body.
4. Keep welding power source and cables as far away from operator as practical.
5. Connect work clamp to workpiece as close to the weld as possible.
About Pacemakers:
Pacemaker wearers consult your doctor first. If cleared by your doctor,
then following the above procedures is recommended.

1-5.Information sur les champs électromagnétiques
Données sur le soudage électrique et sur les ef fets, pour l ’organisme,
des champs magnétiques basse fréquence
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 électromagnéti-
ques pendant le soudage ou le coupage.
Afin de réduire les champs électromagnétiques dans l’environnement
de travail, respecter les consignes suivantes :
1Garder les câbles ensembles en les torsadant ou en les
attachant avec du ruban adhésif.
2Mettre tous les câbles du côté opposé de l’opérateur.
3Ne pas courber pas et ne pas entourer pas les câbles autour de
votre corps.
4Garder le poste de soudage et les câbles le plus loin possible de
vous.
5Relier la pince de masse le plus près possible de la zone de
soudure.
Consignes relatives aux stimulateurs cardiaques :
Les personnes qui portent un stimulateur cardiaque doivent avant tout
consulter leur docteur. Si vous êtes déclaré apte par votre docteur , il est
alors recommandé de respecter les consignes ci–dessus.

3-4.Duty Cycle And Overheating
Duty Cycle is the percentage of 10
minutes that the unit can weld at
rated load without overheating.
If unit overheats, output stops, front
panel voltmeter/ammeter displays
a HLP3 or HLP5 message (see
Section 5-4), and cooling fans run.
Wait fifteen minutes for unit to cool.
Reduce amperage or duty cycle before welding.

3-6.Weld Output Terminals And Selecting Cable Sizes
Y 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.

A - Closure to D starts the weld cycle. Opening closure stops weld cycle. Durning 2T operation, a momentary closure (greater than 100ms, but
less than 3/4 seconds) starts and stops weld output.
B - Closure to D turns on gas. This input will override Postflow, but if a Preflow time is entered, the Preflow cycle will time out before arc initiation.
C - Closure to D must be maintained at all times. If the closure between pins C and D is broken, an output disable occurs, Postflow begins to
time out, and HELP 13 will be displayed on the meters.
Outputs are isolated open-collector transistor which are able to conduct at least 6 mA of current, with a maximum of 100 mA of current and 30
VDC.
Final Slope - output is on when in Final Slope.
Pulse Lockout - output is on when in Initial Amperage, Initial Slope, Final Slope, Final Amperage, and when the pulse frequency is less than 10

1Balance/DIG Control
Balance Control (AC GTAW):
Control changes the AC output
square wave. Rotating the control
towards 10 prov i d e s d e e p e r p e n e tration. Rotating the control towards
0 provides more cleaning action of
the workpiece.
When the control is in the Balanced
position, the wave shape provides
equal penetration and cleaning
action.
Application:
When welding on oxide forming materials such as aluminum or magnesium, excess cleaning is not necessary. To produce a good weld, only
a minimal amount, approximately a
ArcSetting
0.10 in (2.5mm) of etched zone
along the weld toes is required.
Set control to 7 and adjust as necessary. Joint configuration, set-up,
process variables, and oxide thickness may affect setting.
NOTE: Arc rectification can occur
when welding above 200 amps
and/or while welding with helium
gas. If this condition occurs, increasing the Balance control towards maximum penetration, may
help to restabilize the arc.
DIG Control (AC And DC SMAW):
When set at 0, short-circuit amperage at low arc voltage is the same
as normal welding amperage.
When setting is increased, shortcircuit amperage at low arc voltage
increases.
Application:
Control helps arc starting or making
vertical or overhead welds by increasing amperage at low arc voltage, and reduces electrode sticking
while welding.

Use Background Amps control to

puddle and affects overall heat input. Background Amps is set as a
percentage of peak amperage.
3Pulse Frequency
Ranges from 0.25–10.0 pps
(pulses per second). Control is
used to determine appearance o f
weld bead.
4Peak Time
A range of 5–95% of each pulse
cycle can be spent at the peak
amperage level.
Peak amperage (5–310 amps), is
set with the Amperage Adjustment control (see Section 4-1).
Peak amperage is the highest
welding amperage allowed to occur in the pulse cycle. Weld penetration varies directly with peak
amperage.
5Pulsed Output Waveforms
Example shows affect changing
the Peak Time control has on the
pulsed output waveform.
Application:
Pulsing refers to the alternating
raising and lowering of the weld
output at a specific rate. The
raised por t io n s o f t h e w e l d o u t p u t
are controlled in width, height,
and frequency, forming pulses of
weld output. These pulses and
the lower amperage level between them (called the background amperage) alternately
heat and cool the molten weld
puddle. The combined effect
gives the operator better control
of penetration, bead width,
crowning, undercutting, and heat
input. Controls can be adjusted
while welding.
Pulsing can also be used for filler
material addition technique
training.
NOTE: Function is enabled,

NOTE: Arc rectification can occur when welding above 200 amps
and/or while welding with helium gas. If this condition occurs, increasing the HF Intensity control towards maximum, may help to restabilize the arc.

fering with local electronic devices, especially communication
equipment, also increases. Set control as low as possible to
avoid such interference.

8-2.Preparing Tungsten Electrode For Welding
Y Grinding the tungsten electrode produces dust and flying sparks which can cause injury and start fires. Use
local exhaust (forced ventilation) at the grinder or wear an approved respirator. Read MSDS for safety information. Consider using tungsten containing ceria, lanthana, or yttria instead of thoria. Grinding dust from
thoriated electrodes contains low-level radioactive material. Properly dispose of grinder dust in an environmentally safe way. Wear proper face, hand, and body protection. Keep flammables away.
