1-2.Arc Welding Hazards
The symbols shown below are used throughout this manual
to call attention to and identify possible hazards. When you
see the symbol, watch out, and follow the related instructions
to avoid the hazard. The safety information given below is
only a summary of the more complete safety information
found in the Safety Standards listed in Section 1-7. Read and
follow all Safety Standards.
Only qualified persons should install, operate, maintain, and
repair this unit.
During operation, keep everybody, especially children, away.
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
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 grounded equipment is a hazard.
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.
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!
Disconnect input power or stop engine before installing or
servicing this equipment. Lockout/tagout input power according to
OSHA 29 CFR 1910.147 (see Safety Standards).
Properly install and ground this equipment according to its
Owner’s Manual and national, state, and local codes.
Indicates special instructions.
This group of symbols means Warning! Watch Out! ELECTRIC
SHOCK, MOVING PARTS, and HOT PARTS hazards. Consult symbols and related instructions below for necessary actions to avoid the
hazards.
Always verify the supply ground — check and be sure that input
power cord ground wire is properly connected to ground terminal in
disconnect box or that cord plug is connected to a properly
grounded receptacle outlet.
When making input connections, attach proper grounding conduc-
tor first − double-check connections.
Keep cords dry, free of oil and grease, and protected from hot metal
and sparks.
Frequently inspect input power cord for damage or bare wiring —
replace cord immediately if damaged — bare wiring can kill.
Turn off all equipment when not in use.
Do not use worn, damaged, undersized, or poorly spliced cables.
Do not drape cables over your body.
If earth grounding of the workpiece is required, ground it directly
with a separate cable.
Do not touch electrode if you are in contact with the work, ground,
or another electrode from a different machine.
Use only well-maintained equipment. Repair or replace damaged
parts at once. Maintain unit according to manual.
Do not touch electrode holders connected to two welding ma-
chines at the same time since double open-circuit voltage will be
present.
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.
SIGNIFICANT DC VOLTAGE exists in inverters after stopping engine.
Stop engine on inverter and discharge input capacitors according
to instructions in Maintenance Section before touching any parts.
HOT PARTS can cause severe burns.
Do not touch hot parts bare handed.
Allow cooling period before working on equip-
ment.
To handle hot parts, use proper tools and/or wear heavy, insu-
lated welding gloves and clothing to prevent burns.
FLYING METAL or DIRT can injure eyes.
Welding, chipping, wire brushing, and grinding
cause sparks and flying metal. As welds cool,
they can throw off slag.
Wear approved safety glasses with side shields even under your
welding helmet.
OM-4409 Page 1

FUMES AND GASES can be hazardous.
Welding produces fumes and gases. Breathing these
fumes and gases can be hazardous to your health.
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.
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 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.
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
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.
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).
Do not weld where the atmosphere may contain flammable dust,
gas, or liquid vapors (such as gasoline).
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, sparks, and fire hazards.
Do not use welder to thaw frozen pipes.
Remove stick electrode from holder or cut off welding wire at
contact tip when not in use.
Wear oil-free protective garments such as leather gloves, heavy
shirt, cuffless trousers, high shoes, and a cap.
Remove any combustibles, such as a butane lighter or matches,
from your person before doing any welding.
After completion of work, inspect area to ensure it is free of sparks,
glowing embers, and flames.
Use only correct fuses or circuit breakers. Do not oversize or by-
pass them.
Follow requirements in OSHA 1910.252 (a) (2) (iv) and NFPA 51B
for hot work and have a fire watcher and extinguisher nearby.
NOISE can damage hearing.
BUILDUP OF GAS can injure or kill.
Shut off shielding gas supply when not in use.
Always ventilate confined spaces or use ap-
proved air-supplied respirator.
ARC RAYS can burn eyes and skin.
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.
Wear an approved welding helmet fitted with a proper shade of filter
lenses to protect your face and eyes from arc rays and sparks
when welding or watching (see ANSI Z49.1 and Z87.1 listed in
Safety Standards).
Wear approved safety glasses with side shields under your
helmet.
Use protective screens or barriers to protect others from flash,
glare, and sparks; warn others not to watch the arc.
Wear protective clothing made from durable, flame-resistant mate-
rial (leather, heavy cotton, or 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 workpiece,
and hot equipment can cause fires and 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.
Remove all flammables within 35 ft (10.7 m) of the welding arc. If
this is not possible, tightly cover them with approved covers.
Do not weld where flying sparks can strike flammable material.
Protect yourself and others from flying sparks and hot metal.
Be alert that welding sparks and hot materials from welding can
easily go through small cracks and openings to adjacent areas.
Watch for fire, and keep a fire extinguisher nearby.
Be aware that welding on a ceiling, floor, bulkhead, or partition can
cause fire on the hidden side.
Noise from some processes or equipment can damage hearing.
Wear approved ear protection if noise level is
high.
MAGNETIC FIELDS can affect Implanted
Medical Devices.
Wearers of Pacemakers and other Implanted
Medical Devices should keep away.
Implanted Medical Device wearers should consult their doctor
and the device manufacturer before going near arc welding, spot
welding, gouging, plasma arc cutting, or induction heating
operations.
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.
Protect compressed gas cylinders from excessive heat, mechani-
cal shocks, physical damage, slag, open flames, sparks, and arcs.
Install cylinders in an upright position by securing to a stationary
support or cylinder rack to prevent falling or tipping.
Keep cylinders away from any welding or other electrical circuits.
Never drape a welding torch over a gas cylinder.
Never allow a welding electrode to touch any cylinder.
Never weld on a pressurized cylinder — explosion will result.
Use only correct shielding gas cylinders, regulators, hoses, and fit-
tings designed for the specific application; maintain them and
associated parts in good condition.
Turn face away from valve outlet when opening cylinder valve.
Keep protective cap in place over valve except when cylinder is in
use or connected for use.
Use the right equipment, correct procedures, and sufficient num-
ber of persons to lift and move cylinders.
Read and follow instructions on compressed gas cylinders,
associated equipment, and Compressed Gas Association (CGA)
publication P-1 listed in Safety Standards.

1-8.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:

provoquer des brûlures graves.
Ne pas toucher à mains nues les parties chau
des.
Prévoir une période de refroidissement avant d
travailler à l’équipement.
Ne pas toucher aux pièces chaudes, utiliser les outils recomman
dés et porter des gants de soudage et des vêtements épais pou
éviter les brûlures.
DES PIECES DE METAL ou DES SALETES peuvent provoquer des blessures dans les yeux.
Le soudage, l’écaillement, le passage de la pièce à la brosse en
fil de fer, et le meulage génèrent des étincelles et des particules
métalliques volantes. Pendant la période de refroidissement des
soudures, elles risquent de projeter du laitier.
Porter des lunettes de sécurité avec écrans latéraux ou un écran
facial.
LES FUMÉES ET LES GAZ peuvent êtr
dangereux.
Le soudage génère des fumées et des gaz. Leur
inhalation peut être dangereux pour votre santé.
Eloigner votre tête des fumées. Ne pas respirer les fumées.
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
approuvé.
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 surveillant dûment formé de se tenir à proximité. Des fumées et
des gaz de soudage peuvent déplacer l’air et abaisser le niveau
d’oxygène provoquant 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 dégraissage, de nettoyage ou de pulvérisation. La chaleur et
les rayons de l’arc peuvent réagir en présence de vapeurs et former des gaz hautement toxiques et irritants.
Ne pas souder des métaux munis d’un revêtement, tels que l’acier
galvanisé, 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 toxiques en cas de soudage.
LES ACCUMULATIONS DE GAZ ri
quent de provoquer des blessures o
même la mort.
Fermer l’alimentation du gaz protecteur en cas d
non utilisation.
Veiller toujours à bien aérer les espaces confinés ou se servir d’u
respirateur d’adduction d’air homologué.
LES RAYONS DE L’ARC peuvent pr
voquer des brûlures dans les yeux
sur la peau.
Le rayonnement de l’arc du procédé de soudag
génère des rayons visibles et invisibles intense
(ultraviolets et infrarouges) susceptibles de provoquer des brûlure
dans les yeux et sur la peau. Des étincelles sont projetées pendant l
soudage.
Porter un casque de soudage approuvé muni de verres filtrants
approprié pour protéger visage et yeux pendant le soudage
(voir ANSI Z49.1 et Z87.1 énuméré dans les normes de sécurité).
Porter des lunettes de sécurité avec écrans latéraux même sous
votre casque.
Avoir recours à des écrans protecteurs ou à des rideaux pour
protéger les autres contre les rayonnements les éblouissements
et les étincelles ; prévenir toute personne sur les lieux de ne pas
regarder l’arc.
Porter des vêtements confectionnés avec des matières résistan-
tes et ignifuges (cuir, coton lourd ou laine) et des bottes de
protection.
LE SOUDAGE peut provoquer un in
cendie ou une explosion.
Le soudage effectué sur des conteneurs fermés tel
que des réservoirs, tambours ou des conduites pe
provoquer leur éclatement. Des étincelles peuve
être projetées de l’arc de soudure. La projection d’étincelles, des pièce
chaudes et des équipements chauds peut provoquer des incendies
des brûlures. Le contact accidentel de l’électrode avec des objet
métalliques peut provoquer des étincelles, une explosion, un surchau
fement ou un incendie. Avant de commencer le soudage, vérifier
s’assurer que l’endroit ne présente pas de danger.
Déplacer toutes les substances inflammables à une distance de
10,7 m de l’arc de soudage. En cas d’impossibilité les recouvrir
soigneusement avec des protections homologués.
Ne pas souder dans un endroit là où des étincelles peuvent tomber
sur des substances inflammables.
Se protéger et d’autres personnes de la projection d’étincelles et
de métal chaud.
Des étincelles et des matériaux chauds du soudage peuvent
facilement passer dans d’autres zones en traversant de petites
fissures et des ouvertures.
Surveiller tout déclenchement d’incendie et tenir un extincteur à
proximité.
Le soudage effectué sur un plafond, plancher, paroi ou séparation
peut déclencher un incendie de l’autre côté.
Ne pas effectuer le soudage sur des conteneurs fermés tels que
des réservoirs, tambours, ou conduites, à moins qu’ils n’aient été
préparés correctement conformément à AWS F4.1 (voir les normes de sécurité).
Ne soudez pas si l’air ambiant est chargé de particules, gaz, ou va-
peurs inflammables (vapeur d’essence, par exemple).
Brancher le câble de masse sur la pièce le plus près possible de la
zone de soudage pour éviter le transport du courant sur une
longue distance par des chemins inconnus éventuels en provoquant des risques d’électrocution, d’étincelles et d’incendie.
Ne pas utiliser le poste de soudage pour dégeler des conduites ge-
lées.
En cas de non utilisation, enlever la baguette d’électrode du porte-
électrode ou couper le fil à la pointe de contact.
Porter des vêtements de protection dépourvus d’huile tels que des
gants en cuir, une chemise en matériau lourd, des pantalons sans
revers, des chaussures hautes et un couvre chef.
Avant de souder, retirer toute substance combustible de vos po-
ches telles qu’un allumeur au butane ou des allumettes.
Une fois le travail achevé, assurez−vous qu’il ne reste aucune tra-
ce d’étincelles incandescentes ni de flammes.
Utiliser exclusivement des fusibles ou coupe−circuits appropriés.
Ne pas augmenter leur puissance; ne pas les ponter.
Suivre les recommandations dans OSHA 1910.252(a)(2)(iv) et
NFPA 51B pour les travaux à chaud et avoir de la surveillance et un
extincteur à proximité.
LE BRUIT peut affecter l’ouïe.
Le bruit des processus et des équipements peut affe
l’ouïe.
Porter des protections approuvés pour les or
les si le niveau sonore est trop élevé.

2-8.Information EMF
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
les procédures suivantes :
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.
5. Connecter la pince sur la pièce aussi près que possible de la
soudure.
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
points, de gougeage, du coupage plasma ou de chauffage par induction. Si le médecin approuve, il est recommandé de suivre les
procédures précédentes.

if fuel level is low on units with low fuel shutdown option.
To check fuel level when engine is not running, turn Engine Control switch to Run/Idle
position.
5 Air Pressure Gauge
Use gauge to check compressor air pressure.
6 Engine Oil Pressure Gauge
Normal pressure is 30 − 60 psi (206 − 414
kPa). Engine stops if pressure is below 20 psi
(138 kPa).
7 Engine Temperature Gauge
Normal temperature is 212 - 239° F (100 -
115 ° C). Engine stops if temperature exceeds
270° F (132° C).
8 Battery Voltmeter
Use gauge to check battery voltage and moni-
tor the engine charging system. The meter
should read about 14 volts dc when the engine is running, and about 12 volts dc when
the engine is stopped.
9 Air Compressor Hour Meter (Optional)
Use gauge to monitor compressor running
time for scheduling maintenance.
Weld Controls
10 Process/Contactor Switch
See Section 6-3 for Process/Contactor
switch information.
11 Ampere Range Switch
NOTICE − Do not switch under load.
Use switch to select weld amperage range.
Use all five ranges for Stick welding, and the
lowest four ranges for TIG welding. Read the
upper set of numbers at each range for Stick
welding and the lower set at each range for
TIG welding.
Use the highest range for MIG welding and for
cutting and gouging (CAC-A).
For most welding applications, use lowest
amperage range possible to help prevent arc
outages.
12 Voltage/Amperage Adjust Control
With Process/Contactor switch in any Stick or
TIG setting, use control to adjust amperage
within range selected by Ampere Range
switch. With Process/Contactor switch in any
MIG position, use control to adjust voltage.
With Panel/Remote Switch in Remote position, control limits the remote amperage in
TIG mode, but has no effect in Stick and MIG
modes.
Weld output would be about 263 A DC with
controls set as shown (50% of 125 to 400 A).
The numbers around the Voltage/Amper-
age Adjust control are for reference only
and do not represent an actual percentage value.
13 Panel/Remote Switch And Remote 14
Receptacle

Air Compressor Controls
17 Air Compressor Switch
Use switch to turn air compressor on and off.
Air pressure is present at the compressor air
shutoff valve whenever the compressor is
running. The compressor shuts off when the
engine stops. To use air, the compressor must
be turned on each time the engine is started.
The air compressor will not start if still under
pressure. If air compressor is turned off, wait
for air pressure to bleed off (about 20 seconds) before turning air compressor on again.
To extend clutch bearing life, cycle air
compressor off and on once every two
hours during periods of extended use.
18 Air Shutoff Valve
!Air pressure is present at valve when-
ever Air Pressure Gauge (item 5) indicates air pressure.

SECTION 14 − RUN-IN PROCEDURE
NOTICE − Do not perform run-in
procedure at less than 20 volts
weld output and do not exceed duty
cycle or equipment damage may
occur.
1 Welding Generator
2
Run diesel engines near rated voltage and current during run-in period
to properly seat piston rings and
prevent wetstacking. See nameplate, rating label, or specifications
section in this manual to find rated
voltage and current.
NOTICE − Do not idle engine longer
than necessary. Piston rings seat
faster if engine runs at weld/power
rpm, and the welding generator is
kept loaded during run-in.
2 Engine Exhaust Pipe
Wetstacking is unburned fuel and
oil in the exhaust pipe and occurs
during run-in if the engine is run too
long at light load or idle rpm.
If exhaust pipe is coated with a wet,
black, tar-like substance, dry the
engine using one of the following
run-in procedures.
See the engine manual for additional engine run-in information.

considered accurate for any particular make of tool.
Above tools are rated based upon typical “on-load” performance characteristics.
For other values, adjust the C.F. air consumption on a proportional basis.

ST-800 576-B
1 Resistive Load
A light bulb is a resistive load and
requires a constant amount of power.
2 Non-Resistive Load
Equipment with a motor is a non-re-
sistive load and requires approximately six times more power while
starting the motor than when running
(see Section 16-8).
3 Rating Data
Rating shows volts and amperes, or
watts required to run equipment.
Amperes x Volts = Watts
Example 1: If a drill uses 4.5 am-
peres at 115 volts, calculate its running power requirement in watts.
4.5 A x 115 V = 520 W
The load applied by the drill is 520
watts.
Example 2: If three 200 watt flood
lamps are used with the drill from Example 1, add the individual loads to
calculate total load.
(3 x 200W) + 520 W = 1120 W
The total load applied by the three
flood lamps and drill is 1120 watts.

16-5. Approximate Power Requirements For Industrial Motors
4 Welding Generator Output
Generator output voltage and wir-
ing must be consistent with regular
(utility) system voltage and wiring.
Connect generator with temporary
or permanent wiring suitable for the
installation.
Turn off or unplug all equipment
connected to generator before
starting or stopping engine. When
starting or stopping, the engine has
low speed which causes low voltage and frequency.
5 Essential Loads
Generator output may not meet the
electrical requirements of the premises. If generator does not produce
enough output to meet all requirements, connect only essential
loads (pumps, freezers, heaters,
etc. − See Section 16-4).
♦Typical argon shielding gas flow rates are 11 to 35 cfh (cubic feet per hour).

17-2. Preparing Tungsten Electrode For Welding With Phase Control Machines
!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.

SECTION 18 − GUIDELINES FOR TIG WELDING (GTAW)
18-1. Positioning The Torch
!Grinding the tungsten elec-
trode 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 cerium or
lanthanum based tungsten
instead of thoriated. Thorium dust 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.
1 Workpiece
Make sure workpiece is clean
before welding.
2 Work Clamp
Place as close to the weld as
possible.
3 Torch
4 Filler Rod (If Applicable)
5 Gas Cup
6 Tungsten Electrode
Select and prepare tungsten
according to Section 17.
Guidelines:
The inside diameter of the gas cup
should be at least three times the
tungsten diameter to provide adequate shielding gas coverage. (For
example, if tungsten is 1/16 in
diameter, gas cup should be a
minimum of 3/16 in diameter.
Tungsten extension is the distance
the tungsten extends out gas cup of
torch.
The tungsten extension should be
no greater than the inside diameter
of the gas cup.
Arc length is the distance from the
tungsten to the workpiece.
