parts at once. Maintain unit according to manual.  
ELECTRIC SHOCK can kill.  
D
D
D
Wear a safety harness if working above floor level.  
Keep all panels and covers securely in place.  
Clamp work cable with good metal-to-metal contact to workpiece  
or worktable as near the weld as practical.  
Insulate work clamp when not connected to workpiece to prevent  
contact with any metal object.  
Do not connect more than one electrode or work cable to any  
single weld output terminal.  
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  
power circuit and machine internal circuits are also  
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  
groundedequipment is a hazard.  
D
D

D
D
Do not touch live electrical parts.  
Wear dry, hole-free insulating gloves and body protection.  
Insulate yourself from work and ground using dry insulating mats  
or covers big enough to prevent any physical contact with the work  
or ground.  
Do not use AC output in damp areas, if movement is confined, or if  
there is a danger of falling.  
Use AC output ONLY if required for the welding process.  
If AC output is required, use remote output control if present on  
unit.  
SIGNIFICANT DC VOLTAGE exists in inverter-type  
welding power sources after removal of input  
power.  
D
Turn Off inverter, disconnect input power, and discharge input  
capacitors according to instructions in Maintenance Section  
before touching any parts.  
D
D
D
FUMES AND GASES can be hazardous.  
D
Additionalsafety 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 unavoid-  
able or accidental contact with the workpiece or ground. For these  
conditions, use the following equipment in order presented: 1) a  
semiautomaticDC constant voltage (wire) welder, 2) a DC manual  
(stick) welder, or 3) an AC welder with reduced open-circuit volt-  
age. In most situations, use of a DC, constant voltage wire welder  
is recommended. And, do not work alone!  
Welding produces fumes and gases. Breathing  
these fumes and gases can be hazardous to your  
health.  
D
D
Keep your head out of the fumes. Do not breathe the fumes.  
If inside, ventilate the area and/or use local forced ventilation at the  
arc to remove welding fumes and gases.  
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.  
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.  
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.  
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.

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.  
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  
committees 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 Pacemakers:  
Pacemaker wearers consult your doctor before welding or going near  
welding operations. If cleared by your doctor, then following the above  
procedures is recommended.  
To reduce magnetic fields in the workplace, use the following  
procedures:

trous.  
S’isoler de la pièce à couper et du sol en utilisant des housses ou des  
tapis assez grands afin d’éviter tout contact physique avec la pièce à  
couper ou le sol.  
Ne pas se servir de source électrique à courant électrique dans les zo-  
nes humides, dans les endroits confinés ou là où on risque de tomber.  
Se servir d’une source électrique à courant électrique UNIQUEMENT si  
le procédé de soudage le demande.  
Si l’utilisation d’une source électrique à courant électrique s’avère né-  
cessaire, se servir de la fonction de télécommande si l’appareil en est  
équipé.  
Il reste une TENSION DC NON NÉGLIGEABLE dans  
les sources de soudage onduleur quand on a coupé  
l’alimentation.  
D
D
Arrêter les convertisseurs, débrancher le courant électrique et  
décharger les condensateurs d’alimentation selon les instructions indi-  
quées dans la partie Entretien avant de toucher les pièces.  
D
D
D
LES FUMÉES ET LES GAZ peuvent  
être dangereux.  
Le soudage génère des fumées et des gaz. Leur  
inhalationpeut être dangereuse pour la santé.  
D
D’autres consignes de sécurité sont nécessaires dans les conditions  
suivantes : risques électriques dans un environnement humide ou si l’on  
porte des vêtements mouillés ; sur des structures métalliques telles que  
sols, grilles ou échafaudages ; en position coincée comme assise, à ge-  
noux ou couchée ; ou s’il y a un risque élevé de contact inévitable ou  
accidentel avec la pièce à souder ou le sol. Dans ces conditions, utiliser  
les équipements suivants, dans l’ordre indiqué : 1) un poste à souder DC  
à tension constante (à fil), 2) un poste à souder DC manuel (électrode)  
ou 3) un poste à souder AC à tension à vide réduite. Dans la plupart des  
situations, l’utilisation d’un poste à souder DC à fil à tension constante  
est recommandée. En outre, ne pas travailler seul !  
Couper l’alimentation ou arrêter le moteur avant de procéder  
à l’installation, à la réparation ou à l’entretien de l’appareil. Déverrouiller  
l’alimentation selon la norme OSHA 29 CFR 1910.147 (voir normes de  
sécurité).

Ne pas mettre sa tête au-dessus des vapeurs. Ne pas respirer ces va-  
peurs.  
À l’intérieur, ventiler la zone et/ou utiliser une ventilation forcée au niveau de  
l’arc pour l’évacuation des fumées et des gaz de soudage.  
Si la ventilation est médiocre, porter un respirateur anti-vapeurs approu-  
vé.  
Lire et comprendre les spécifications de sécurité des matériaux (MSDS) et  
les instructions du fabricant concernant les métaux, les consommables, les  
revêtements, les nettoyants et les dégraisseurs.  
Travailler dans un espace fermé seulement s’il est bien ventilé ou en  
portant un respirateur à alimentation d’air. Demander toujours à un sur-  
veillant dûment formé de se tenir à proximité. Des fumées et des gaz de  
soudage peuvent déplacer l’air et abaisser le niveau d’oxygène provo-  
quant des blessures ou des accidents mortels. S’assurer que l’air de  
respiration ne présente aucun danger.  
Ne pas souder dans des endroits situés à proximité d’opérations de dé-  
graissage, de nettoyage ou de pulvérisation. La chaleur et les rayons de  
l’arc peuvent réagir en présence de vapeurs et former des gaz haute-  
ment toxiques et irritants.  
Ne pas souder des métaux munis d’un revêtement, tels que l’acier gal-  
vanisé, plaqué en plomb ou au cadmium à moins que le revêtement n’ait  
été enlevé dans la zone de soudure, que l’endroit soit bien ventilé et en  
portant un respirateur à alimentation d’air. Les revêtements et tous les  
métaux renfermant ces éléments peuvent dégager des fumées toxi-  
ques en cas de soudage.

4-3. Duty Cycle And Overheating  
Duty Cycle is percentage of 10 min-  
utes that unit can weld at rated load  
without overheating.  
If unit overheats, output stops, and  
cooling fan runs. Wait fifteen min-  
utes for unit to cool. Reduce amper-  
age or duty cycle before welding.

2 “Time-Delay” fuses are UL class “RK5” .  
3 “Normal Operating” (general purpose - no intentional delay) fuses are UL class “K5” (up to and including 60 amp), and UL class “H” ( 65 amp and  
above).  
4 Conductor data in this section specifies conductor size (excluding flexible cord or cable) between the panelboard and the equipment per NEC Table  
310.16. If a flexible cord or cable is used, minimum conductor size may increase. See NEC Table 400.5(A) for flexible cord and cable requirements.

TIG Electrode  
Workpiece  
Turn gas on. Touch tungsten elec-  
trode to workpiece at weld start  
point. Hold electrode to work-

Normal open-circuit voltage is not  
present before tungsten electrode  
touches workpiece; only a low  
sensing voltage is present between  
electrode and workpiece. The  
solid-state output contactor does  
not energize until after electrode is  
touching workpiece. This allows  
electrode to touch workpiece with-  
out overheating, sticking, or getting  
contaminated.

Control increases SMAW short-cir-  
cuit amperage at low arc voltage.  
This allows the operator to use a  
very short arc length without stick-  
ing the electrode.  
Set control at 0 for normal welding  
amperage. Turn clockwise to in-  
crease short-circuit amperage.

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 infor-  
mation. 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 environ-  
mentally safe way. Wear proper face, hand, and body protection. Keep flammables away.
