Y 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

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 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).

D Properly install and ground this equipment according to its

Owner’s Manual and national, state, and local codes.

D 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.

D When making input connections, attach proper grounding conduc-

tor first − double-check connections.

D Frequently inspect input power cord for damage or bare wiring −

replace cord immediately if damaged − bare wiring can kill.

to avoid the hazards.

D Turn off all equipment when not in use.
D Do not use worn, damaged, undersized, or poorly spliced cables.
D Do not drape cables over your body.
D If earth grounding of the workpiece is required, ground it directly

with a separate cable.

D Do not touch electrode if you are in contact with the work, ground,

or another electrode from a different machine.

D Do not touch electrode holders connected to two welding ma-

chines at the same time since double open-circuit voltage will be
present.

D Use only well-maintained equipment. Repair or replace damaged

parts at once. Maintain unit according to manual.

D Wear a safety harness if working above floor level.
D Keep all panels and covers securely in place.
D Clamp work cable with good metal-to-metal contact to workpiece

or worktable as near the weld as practical.

D Insulate work clamp when not connected to workpiece to prevent

contact with any metal object.

D Do not connect more than one electrode or work cable to any

single weld output terminal.

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.

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.

OM-216 244 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 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.

D Use protective screens or barriers to protect others from flash,

glare and sparks; warn others not to watch the arc.

D 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

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 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 Do not weld where flying sparks can strike flammable material.
D Protect yourself and others from flying sparks and hot metal.
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, sparks, 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.

D Remove any combustibles, such as a butane lighter or matches,

from your person before doing any welding.

D Follow requirements in OSHA 1910.252 (a) (2) (iv) and NFPA 51B

for hot work and have a fire watcher and extinguisher nearby.

workpiece, and hot equipment can cause fires and

FLYING METAL can injure eyes.

D Welding, chipping, wire brushing, and grinding

cause sparks and flying metal. As welds cool,
they can throw off slag.

D Wear approved safety glasses with side

shields even under your welding helmet.

D Shut off shielding gas supply when not in use.
D Always ventilate confined spaces or use

approved air-supplied respirator.

HOT PARTS can cause severe burns.

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:

D Arrêter les convertisseurs, débrancher le courant électrique et

décharger les condensateurs d’alimentation selon les instructions indi­quées dans la partie Entretien avant de toucher les pièces.

LES FUMÉES ET LES GAZ peuvent
être dangereux.

Le soudage génère des fumées et des gaz. Leur
inhalation peut être dangereuse pour la santé.

D Ne pas mettre sa tête au-dessus des vapeurs. Ne pas respirer ces va-

peurs.

D 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.

D Si la ventilation est médiocre, porter un respirateur anti-vapeurs approu-

vé.

D 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.

D 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.

D 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 haute­ment toxiques et irritants.

D 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 toxi­ques en cas de soudage.

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

4-3. Weld Output Receptacles 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.

5-7. Plunge Adjustment

Plunge Settings When Using Ferrules

1

Plunge controls the amount of stud that is
melted during the arc time. Too much plunge
and the fillet will overfill the ferrule or create
excessive splatter when using a spark
shield. Too little plunge and there may be in­complete fillet formation. There should be
approximately 1/8 of an inch of stud protrud­ing past the end of the ferrule. A bit less for
smaller studs, a bit more for larger studs.

. These instructions are for standard fer-

rules. For reduced fillet ferrules (only
recommended for very specific applica­tions) decrease the amount of plunge by
half.

Plunge Settings For Short Arc or Gas Arc
Stud Welding

For Short Arc or Gas Short Arc the stud
should protrude past the end of the spark
shield by about 0.04 in (1 mm). This is about
the same as the flange thickness on f langed
style studs. For standard time duration Gas
Short Arc the plunge should be set at about
2 flange thicknesses or 0.08 in (2 mm).

LIft Adjustment Table

1/16 in (1.6 mm) lift for studs up to 5/16 (7.9 mm) diameter

3/32 in (2.4 mm) lift for studs over 5/16 (7.9 mm) to 1/2 in (13 mm) diameter

1/8 in (3.2 mm) lift for studs over 1/2 (13 mm) diameter

The lift controls the arc length and is a factor
in controlling the heat of the welding process.

Lift should be set at 3/32 or .094 in (2.5 mm).

Measuring LIft
Y For safety from accidental activation,

always disconnect the weld cable
from the power source before making
any stud gun adjustments or per­forming any service on the stud gun.

1 Stud Lift Measurement
To measure stud lift, hold a scale against

some fixed part of the tool. The front cover or
foot will work well. Press the trigger so the
tool activates the lift mechanism. Now mea­sure again. The lift is the difference between
the two measurements.

Adjusting Lift

2 Location of Core Set Screws
To adjust lift, remove the slotted screw hold-

ing the rear cap in place. Remove rear cap.
Loosen the nylon tipped set screw that holds
the adjustable core in place. To increase lift,
turn the adjustable core screw counter
clockwise. To decrease lift, turn the adjust­able core screw clockwise. Each half turn
equals .025 in (0.6 mm).

Once lift is set, retighten nylon tipped set
screw to keep the adjustable core in place.

Install rear cap and tighten cap screw.

. Keep cap in place to prevent dirt from en-

tering the stud gun mechanism

7-2. Stud Welding Procedures

Y Disconnect gun from power source

before installing or removing compo­nents.

The stud gun automates the stud welding
process.

Several key functions are:

• Holds the ferrule, spark shield or gas de­livery system

• Holds the stud

• Strikes the arc

• Establishes the arc length (lift distance)

• Thru the power source, the gun controls

the arc time

• Controls rate of plunge of the stud into
the base metal

. Before welding it is important to review

the set up. Correct set up will produce
the best welding results. Approximately
95% of all stud welding problems are
due to improper gun set up or power set­tings.

Welding Procedures:

• Place stud to be welded into weld chuck.

• Insert a ferrule into the ferrule grip (this

step is not necessary if using a spark shield)

• Position end of stud in location to be
welded.

• Press gun downward so the ferrule is sit­ting on the base metal.

• Pull trigger to begin weld sequence.

• Hold gun still during the arcing process.

• After weld is complete, continue to hold

the gun still for 1 second to allow the molten
metal to solidify.

• Remove the gun from the welded stud.
Be sure and pull the gun straight off of the
welded stud to prevent damage to the weld
chuck.

• Break away the ferrule and inspect the
weld. (Only applies if ferrule was used)

When is Maintenance Required?

Maintenance requirements will vary with environment and usage. Dirty
work areas or high volume stud welding will require more frequent main­tenance.

There are three primary reasons for maintenance:

• Dirt - Dirt can enter the lifting mechanism and cause erratic lift and
plunge operations. Typically , cleaning is all that is required.

• Wear - Components do wear out over time. Typically, items such
as plastic bearings or cables wear out and need to be replaced.

• Improper Use - Components can arc out by inadvertently placing
them against grounded materials during a weld sequence. Also, by us­ing the gun as a hammer to test welds will damage parts and require
maintenance.

Maintenance Steps

Proper Maintenance Procedures:

• Disassemble the gun.

• Inspect all parts for wear or damage.

• Replace worn or damaged components.

• Clean all components.

• Reassemble components.

• Adjust settings and test.

Disassembly / Assembly Procedures:
Y To prevent accidental activation disconnect the gun from the

power source before adjusting or servicing the gun.

. Items referenced ( ) will correspond with list items.

1 Legs: Loosen set screws (23) and pull legs (not shown) straight out.

Inspect legs for damage and straightness, replace if necessary.

2 Chuck (Not Shown): Insert chuck key into chuck adapter and turn

key 180 degrees. Inspect chuck for damage. If taper on chuck
appear worn out replace chuck.

3 Dust Bellows (3): Remove dust bellows by sliding over end of chuck

adapter. The bellows prevent contaminates from entering the
internal mechanisms of the gun. If bellows has holes or is torn,
replace.

OM-216 244 Page 28

4 Chuck Adapter (2): Unscrew chuck adapter counter clockwise from

cable clamp adapter. Important that chuck adapter is tight on cable
clamp adapter to form a tight connection. An effective way of
removing the adapter is to insert a round rod through two of the
chuck eject holes.

Replace chuck adapter if inside surface or threads are pitted or
damaged.

5 Front Cover Nuts (1): The front cover is held on with two nuts. Use

a 3/4 inch wrench to remove them. Inspect the plastic bearing (4)
for damage or excessive wear.

6 Front Cover (5): If gun is equipped with a plunge dampener it is

located in the front cover. Inspect front cover for cracks and replace
if cracked. The front cover prevents dirt from entering the internal
mechanism and maintains alignment of internal components.

7 Plunge Dampener (7): The dampener is inside the front cover. It

pulls straight out and pushes straight back in. When the plunge
dampener is activated by a finger it should offer continuous
resistance over the entire range of travel. The plunger should then
return, by itself, to full extension. If this is not the case the dampener
needs to be replaced.

8 Cable Clamp Adapter (8): Remove two #10−32 x 5/8 socket head

cap screws (6) from cable clamp adapter. The cable clamp adapter
will separate from the lifting rod. Maneuver the cable clamp adapter
forward between the leg inserts. Remove the #8−32 x 1/2 cap
screw (11) from the back of the cable clamp adapter (8).

Inspect threads on cable clamp adapter. If threads are damage re­place cable clamp adapter. This item transfers all the weld current.
If there is damage to the threads, arcing will continue and poten­tially fuse all the components together.

9 Lifting Mechanism: The lifting mechanism consists of the lifting rod

(12), main spring (13), lift release (14), moveable core (15−20) and
core return spring (21). To disassemble, press the lift release ring
tight against the moveable core and pull the lifting rod out of the
assembly. All components listed above, will come apart.

10 Lifting Rod (12): Inspect lifting rod for wear or damage. The brass

inserts should show no signs of loosening. The steel shaft should
not have any nicks on it. Run a finger over the shaft. If you can feel
grooves from the lifting bearing then the lifting rod is worn out.
Typically the lifting rod and lift bearing should be replaced as a set.
When reassembling, the shaft should have a light film of grease (a
lithium based grease) applied.

11 Disassembly of Moveable Core (15 - 20): Remove snap ring (20)

from shaft (18) of core assembly. The snap ring acts as a spring
seat and is important to maintain proper spring tension. Where the
core assembles into the bearing housing is another retaining ring
(19). This retaining ring can be removed with a small flat bladed
screw driver. After removing the second retaining ring the bearing
housing (15) will separate from the core shaft. The lift bearing (16)
and the lift bearing spring (17) can now be removed.

When reassembling the lift bearing cage must oriented toward the
lift bearing spring. Put a light film of grease (such as a lithium based
grease) over the lift bearing and the lift bearing spring.

12 Handle Covers (35): Remove 3 flat head screws (36 - 37) that retain

the handle cover. Inspect handle cover for breakage.

13 Weld Cable (40): The weld cable can lift out of the gun body. Be

careful unthreading the internal weld cable (9) from inside the body.
The internal and external weld cables can be unscrewed from the
weld cable anchor plate (32). Note the orientation of the weld cable
anchor plate. The radius corner goes toward the top of the body.

Inspect the internal weld cable for frayed or broken wires. If starting
to fray, the internal cable should be replaced.

Inspect weld cable for fraying. Also inspect strain relief (38) for
tears. Inspect cable jacketing for breaks, cuts or tears. If cable
shows signs of damage or wear it should be replaced. In addition,
inspect the weld−lok connector (39). If pitted or damaged, replace.
Inspect weld cable to camlok joint to ensure there is no fraying of
the weld cable.

14 Control Cable (42) (if desired): The control cable is removed by

cutting the wires by the splice connectors. Inspect the control cable
for damage. This includes the strain relief (41) and the insulating
jacketing. If damaged, replace the control cable.

When reinstalling the control cable, there are typically two different
color schemes.
Scheme one: Black and White wires connect to the trigger - Blue
and Brown Wiresconnect to the coil
Scheme two: Black and White wires connect to the trigger - Red and
Green wires connect to the coil.
Make sure all crimp connections are tight and there is no opportuni­ty for electrical shorting.

15 Trigger Switch (31): The trigger switch is a screw in style. Grabbing

it can be difficult. A 1/2” collet is the ideal removal tool. Use an ohm
meter to check trigger functionality.

16 Rear Cap (29): Unscrew and remove. The rear cap prevents dirt

and other contaminates from entering into the gun mechanism.

. Do not use rear of gun as a hammer to check quality of stud weld

for this will damage the rear cap.

17 Adjustable Core (28): Loosen nylon tipped set screw (27) in rear coil

yoke which holds the adjustable core. Completely unscrew and
remove adjustable core.

18 Rear Coil Yoke (26): Loosen the nylon tipped set screw retaining the

rear coil yoke. To perform this the hex key will have to go into the
opening on an angle to reach the set screw. Once the retaining
screw is loosened use a large wrench to unscrew the rear coil yoke.

19 Coil (25): Coil wires (black and red or green and red inside the gun

handle) must be cut prior to coil removal. Cut wires inside the
handle. After coil wires are free, the coil can be pulled straight out

the rear of the gun. Coil condition - check to make sure there is no
varnish odor (a sign of overheating), heavy discoloration (another
sign of overheating) and verify coil resistance at 19 ohms +/− 1 ohm.

20 Front Coil Yoke (24): In front of the coil is the front coil yoke. This

is a tight fit and may be difficult to remove. The front coil yoke
contains a plastic bearing (4). This bearing should be inspected for
wear or damage and replaced if necessary. During reassembly,
make sure the bearing flange is seated in the counterbore on the
front coil yoke. When putting the front coil yoke back into the coil
can, make sure the bearing flange is facing rear of gun.

Check alignment of the foot.

Service the gun to ensure lift/release actions are functioning properly.

Too little plunge. Increase amount of stud extending past end of ferrule or spark shield.

Too little weld time or current. Check Section 7 for base line power recommendations.

Too much plunge. Decrease amount of stud extending past end of ferrule or spark shield.

Dampener Required. If you have a dampener the dampener may have worn out and need replace­ment. See optional equipment in Section 12.

Too much Current or Time. Check Section 7 for base line power recommendations.

Not enough weld current or time. Check Section 7 for base line power recommendations.

If you are attempting short arc you may not be able to eliminate this condition. To improve this situa­tion shorten time and increase current. If the results continue to be unsatisfactory then you may need
to add a shielding gas.

Check gas flow/type of shielding gas.

If using flux loaded studs, check to make sure there is a flux load present in the end of the stud.

Check gun coil connections.

Check for gun coil short or open. There should be 19 ohms of resistance in the gun coil.

Check adjustable core and make sure it is not bottomed out (turned into far clockwise).

Short stud and cant get enough to ex­tend past the ferrule

MILLER PRODUCTS ARE INTENDED FOR PURCHASE AND
USE BY COMMERCIAL/INDUSTRIAL USERS AND PERSONS
TRAINED AND EXPERIENCED IN THE USE AND

Miller. Therefore no compensation or reimbursement for
transportation costs of any kind will be allowed.

TO THE EXTENT PERMITTED BY LAW, THE REMEDIES
PROVIDED HEREIN ARE THE SOLE AND EXCLUSIVE
REMEDIES. IN NO EVENT SHALL MILLER BE LIABLE FOR
DIRECT, INDIRECT, SPECIAL, INCIDENTAL OR

ANY EXPRESS WARRANTY NOT PROVIDED HEREIN AND
ANY IMPLIED WARRANTY, GUARANTY OR

INCLUDING ANY IMPLIED WARRANTY OF
MERCHANTABILITY OR FITNESS FOR PARTICULAR
PURPOSE, WITH RESPECT TO ANY AND ALL EQUIPMENT
FURNISHED BY MILLER IS EXCLUDED AND DISCLAIMED
BY MILLER.

Some states in the U.S.A. do not allow limitations of how long an
implied warranty lasts, or the exclusion of incidental, indirect,
special or consequential damages, so the above limitation or
exclusion may not apply to you. This warranty provides specific
legal rights, and other rights may be available, but may vary from
state to state.

In Canada, legislation in some provinces provides for certain
additional warranties or remedies other than as stated herein,
and to the extent that they may not be waived, the limitations and
exclusions set out above may not apply. This Limited Warranty
provides specific legal rights, and other rights may be available,
but may vary from province to province.
