Miller Copilot is a portable Collaborative Arc Welding System. The system is
designed to meet applicable North American safety standards listed in the
specifications section of this manual. The system includes a Miller Cobot, controller,
welding power source and welding torch all integrated onto a unified cart, ready for
you to connect power, gas, and wire.
Intended Use Of Miller Copilot
Miller collaborative arc welding systems have been designed for safe operation in a
collaborative production environment. This Collaborative Robot (Cobot) has been
designed to provide you the repetitive precision and endurance of robots, while
working in the same workspace, side by side with the individual skills and ability of
people. To achieve this capability, the safety related control system is designed to
control key parameters such as speed and force to ensure safe operation in the
shared workspace.
The system has a single, fixed cobot workspace shared with and contained within a
larger, single operator workspace.
Working as hard as you do −
every power source from
Miller is backed by the most
hassle-free warranty in the
business.
The cobot performs weld process production tasks on the materials that are loaded
and unloaded by an operator.
During normal production tasks, there is the potential for direct interaction between
the cobot and the operator, however, unintentional direct interaction is possible due
to a lack of a physical barrier separating the cobot workspace from that of the
production personnel. As such, the cobot can only operate under power and force
limited control at slower speeds in accordance with ISO/TS 15066:2016 thereby
reducing risk of unintended contact between the cobot and production personnel.
Miller collaborative arc welding systems are manufactured and shipped as
unapplied welding systems. These systems are designed for welding related
applications. Miller Welding Automation (MWA) has made an assessment to identify
the tasks associated with these applications. These tasks are considered in this risk
assessment at the end of this manual.
Important: Tooling, fixtures, and other equipment added to the robotic cell
after delivery may change the type and number of hazards present in and
around the cobot system. A review of the safety and another risk assessment
must be made after installation of any additional equipment to the robotic cell.

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.
cuits 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.
l Do not touch live electrical parts.
l Wear dry, hole-free insulating gloves and body protection.
l Insulate yourself from work and ground using dry insulating mats
or covers big enough to prevent any physical contact with the work
or ground.
l Do not use AC weld output in damp, wet, or confined spaces, or if
there is a danger of falling.
l Use AC output ONLY if required for the welding process.
l If AC output is required, use remote output control if present on
unit.
l 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
The input power circuit and machine internal cir-
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 these hazards.
(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!
l Disconnect input power or stop engine before installing or servic-
ing this equipment. Lockout/tagout input power according to
OSHA 29 CFR 1910.147 (see Safety Standards).
l Properly install, ground, and operate this equipment according to
its Owner’s Manual and national, state, and local codes.
l 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.
l When making input connections, attach proper grounding conduc-
tor first—double-check connections.
l Keep cords dry, free of oil and grease, and protected from hot met-
al and sparks.
l Frequently inspect input power cord and ground conductor for
damage or bare wiring — replace immediately if damaged — bare
wiring can kill.
l Turn off all equipment when not in use.
l Do not use worn, damaged, undersized, or repaired cables.
l Do not drape cables over your body.
l If earth grounding of the workpiece is required, ground it directly
with a separate cable.
l Do not touch electrode if you are in contact with the work, ground,
or another electrode from a different machine.
l Use only well-maintained equipment. Repair or replace damaged
parts at once. Maintain unit according to manual.
l Do not touch electrode holders connected to two welding ma-
chines at the same time since double open-circuit voltage will be
present.
l Wear a safety harness if working above floor level.
l Keep all panels and covers securely in place.
l Clamp work cable with good metal-to-metal contact to workpiece
or worktable as near the weld as practical.
l Insulate work clamp when not connected to workpiece to prevent
contact with any metal object.
l Do not connect more than one electrode or work cable to any sin-
gle weld output terminal. Disconnect cable for process not in use.
l Use GFCI protection when operating auxiliary equipment in damp
or wet locations.

HOT PARTS can burn.
l Do not touch hot parts bare handed.
l Allow cooling period before working on equipment.
l To handle hot parts, use proper tools and/or wear
heavy, insulated welding gloves and clothing to
prevent burns.
FLYING METAL OR DIRT can injure
eyes.
l Welding, chipping, wire brushing, and grinding
cause sparks and flying metal. As welds cool, they
can throw off slag.
l Wear approved safety glasses with side shields even under your
welding helmet.
FUMES AND GASES can be
hazardous.
Welding produces fumes and gases. Breathing
these fumes and gases can be hazardous to your
health.
l Keep your head out of the fumes. Do not breathe the fumes.
l Ventilate the work area and/or use local forced ventilation at the
arc to remove welding fumes and gases. The recommended way
to determine adequate ventilation is to sample for the composition
and quantity of fumes and gases to which personnel are exposed.
l If ventilation is poor, wear an approved air-supplied respirator.
l Read and understand the Safety Data Sheets (SDSs) and the
manufacturer’s instructions for adhesives, coatings, cleaners, consumables, coolants, degreasers, fluxes, and metals.
l Work in a confined space only if it is well ventilated, or while wear-
ing 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.
l Do not weld in locations near degreasing, cleaning, or spraying
operations. The heat and rays of the arc can react with vapors to
form highly toxic and irritating gases.
l Do not weld on coated metals, such as galvanized, lead, or cadmi-
um 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.
BUILDUP OF GAS can injure or kill.
l Shut off compressed gas supply when not in use.
l Always ventilate confined spaces or use approved
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.
l Wear an approved welding helmet fitted with a proper shade of fil-
ter 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).
l Wear approved safety glasses with side shields under your
helmet.
l Use protective screens or barriers to protect others from flash,
glare, and sparks; warn others not to watch the arc.
l Wear body protection made from leather or flame-resistant cloth-
ing (FRC). Body protection includes oil-free clothing such as leather gloves, heavy shirt, cuffless trousers, high shoes, and a cap.
OM-291865 Page 2
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.
l Remove all flammables within 35 ft (10.7 m) of the welding arc. If
this is not possible, tightly cover them with approved covers.
l Do not weld where flying sparks can strike flammable material.
l Protect yourself and others from flying sparks and hot metal.
l Be alert that welding sparks and hot materials from welding can
easily go through small cracks and openings to adjacent areas.
l Watch for fire, and keep a fire extinguisher nearby.
l Be aware that welding on a ceiling, floor, bulkhead, or partition can
cause fire on the hidden side.
l Do not cut or weld on tire rims or wheels. Tires can explode if
heated. Repaired rims and wheels can fail. See OSHA 29 CFR
1910.177 listed in Safety Standards.
l Do not weld on containers that have held combustibles, or on
closed containers such as tanks, drums, or pipes unless they are
properly prepared according to AWS F4.1 (see Safety Standards).
l Do not weld where the atmosphere can contain flammable dust,
gas, or liquid vapors (such as gasoline).
l 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.
l Do not use welder to thaw frozen pipes.
l Remove stick electrode from holder or cut off welding wire at con-
tact tip when not in use.
l Wear body protection made from leather or flame-resistant cloth-
ing (FRC). Body protection includes oil-free clothing such as leather gloves, heavy shirt, cuffless trousers, high shoes, and a cap.
l Remove any combustibles, such as a butane lighter or matches,
from your person before doing any welding.
l After completion of work, inspect area to ensure it is free of sparks,
glowing embers, and flames.
l Use only correct fuses or circuit breakers. Do not oversize or by-
pass them.
l Follow requirements in OSHA 1910.252 (a) (2) (iv) and NFPA 51B
for hot work and have a fire watcher and extinguisher nearby.
l Read and understand the Safety Data Sheets (SDSs) and the
manufacturer’s instructions for adhesives, coatings, cleaners, consumables, coolants, degreasers, fluxes, and metals.
NOISE can damage hearing.
Noise from some processes or equipment can
damage hearing.
l Wear approved ear protection if noise level is high.
ELECTRIC AND MAGNETIC FIELDS
(EMF) can affect Implanted Medical
Devices.
l Wearers of Pacemakers and other Implanted Med-
ical Devices should keep away.
l 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.
Compressed gas cylinders contain gas under high
pressure. If damaged, a cylinder can explode.
Since gas cylinders are normally part of the weld-
ing process, be sure to treat them carefully.
l Protect compressed gas cylinders from excessive heat, mechani-
cal shocks, physical damage, slag, open flames, sparks, and arcs.
l Install cylinders in an upright position by securing to a stationary
support or cylinder rack to prevent falling or tipping.
l Keep cylinders away from any welding or other electrical circuits.
l Never drape a welding torch over a gas cylinder.
l Never allow a welding electrode to touch any cylinder.
l Never weld on a pressurized cylinder—explosion will result.
l Use only correct compressed gas cylinders, regulators, hoses,
and fittings designed for the specific application; maintain them

1-7.EMF Information
Electric current flowing through any conductor causes localized electric and magnetic fields (EMF). The current from arc welding (and allied processes including spot welding, gouging, plasma arc cutting,
and induction heating operations) creates an EMF field around the
welding circuit. EMF fields can interfere with some medical implants,
e.g. pacemakers. Protective measures for persons wearing medical
implants have to be taken. For example, restrict access for passers
−by or conduct individual risk assessment for welders. All welders
should use the following procedures in order to minimize exposure to
EMF fields from the welding circuit:
1. Keep cables close together by twisting or taping them, or using a
cable cover.
2. Do not place your body between welding cables. Arrange cables
to one side and away from the operator.
3. Do not coil or drape cables around your body.
4. Keep head and trunk as far away from the equipment in the welding circuit as possible.
5. Connect work clamp to workpiece as close to the weld as
possible.
6. Do not work next to, sit or lean on the welding power source.
7. Do not weld whilst carrying the welding power source or wire
feeder.
About Implanted Medical Devices:
Implanted Medical 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 recommended.

dés et porter des gants de soudage et des vêtements épais pour
éviter les brûlures.
DES PIECES DE METAL ou DES
SALETES peuvent provoquer des
blessures dans les yeux.
l 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.
l Porter des lunettes de sécurité avec écrans latéraux ou un écran
facial.
LES FUMÉES ET LES GAZ peuvent
être dangereux.
Le soudage génère des fumées et des gaz. Leur
inhalation peut être dangereux pour votre santé.
l Eloigner votre tête des fumées. Ne pas respirer les fumées.
l 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. Pour déterminer la bonne ventilation, il est recommandé de
procéder à un prélèvement pour la composition et la quantité de
fumées et de gaz auxquelles est exposé le personnel.
l Si la ventilation est médiocre, porter un respirateur anti-vapeurs
approuvé.
l Lire et comprendre les fiches de données de sécurité et les ins-
tructions du fabricant concernant les adhésifs, les revêtements,
les nettoyants, les consommables, les produits de refroidissement, les dégraisseurs, les flux et les métaux.
l 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.
l 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.
l 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
risquent de provoquer des blessures
ou même la mort.
l Fermer l’alimentation du gaz comprimé en cas de
non utilisation.
l Veiller toujours à bien aérer les espaces confinés ou se servir d’un
respirateur d’adduction d’air homologué.
LES RAYONS DE L’ARC peuvent
provoquer des brûlures dans les
yeux et sur la peau.
Le rayonnement de l’arc du procédé de soudage
génère des rayons visibles et invisibles intenses
(ultraviolets et infrarouges) susceptibles de provoquer des brûlures
dans les yeux et sur la peau. Des étincelles sont projetées pendant le
soudage.
l 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).
l Porter des lunettes de sécurité avec écrans latéraux même sous
votre casque.
l Avoir recours à des écrans protecteurs ou à des rideaux pour pro-
téger les autres contre les rayonnements les éblouissements et
les étincelles ; prévenir toute personne sur les lieux de ne pas regarder l’arc.
l Porter une protection corporelle en cuir ou des vêtements ignifu-
ges (FRC). La protection du corps comporte des vêtements sans
huile, comme des gants de cuir, une chemise solide, des pantalons sans revers, des chaussures hautes et une casquette.
LE SOUDAGE peut provoquer un
incendie ou une explosion.
Le soudage effectué sur des conteneurs fermés
tels que des réservoirs, tambours ou des conduites
peut provoquer leur éclatement. Des étincelles
peuvent être projetées de l’arc de soudure. La projection d’étincelles,
des pièces chaudes et des équipements chauds peut provoquer des
incendies et des brûlures. Le contact accidentel de l’électrode avec
des objets métalliques peut provoquer des étincelles, une explosion,
un surchauffement ou un incendie. Avant de commencer le soudage,
vérifier et s’assurer que l’endroit ne présente pas de danger.
l 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.
l Ne pas souder dans un endroit là où des étincelles peuvent tom-
ber sur des substances inflammables.
l Se protéger et d’autres personnes de la projection d’étincelles et
de métal chaud.
l Des étincelles et des matériaux chauds du soudage peuvent faci-
lement passer dans d’autres zones en traversant de petites fissures et des ouvertures.
l Surveiller tout déclenchement d’incendie et tenir un extincteur à
proximité.
l Le soudage effectué sur un plafond, plancher, paroi ou séparation
peut déclencher un incendie de l’autre côté.
l Ne pas couper ou souder des jantes ou des roues. Les pneus peu-
vent exploser s’ils sont chauffés. Les jantes et les roues réparées
peuvent défaillir. Voir OSHA 29 CFR 1910.177 énuméré dans les
normes de sécurité.
l 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).
l Ne pas souder là où l’air ambiant pourrait contenir des poussières,
gaz ou émanations inflammables (vapeur d’essence, par
exemple).
OM-291865 Page 7
Page 12
l 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.
l Ne pas utiliser le poste de soudage pour dégeler des conduites
gelées.
l En cas de non utilisation, enlever la baguette d’électrode du porte-
électrode ou couper le fil à la pointe de contact.
l Porter une protection corporelle en cuir ou des vêtements ignifu-
ges (FRC). La protection du corps comporte des vêtements sans
huile, comme des gants de cuir, une chemise solide, des pantalons sans revers, des chaussures hautes et une casquette.
l Avant de souder, retirer toute substance combustible de vos po-
ches telles qu’un allumeur au butane ou des allumettes.
l Une fois le travail achevé, assurez-vous qu’il ne reste aucune
trace d’étincelles incandescentes ni de flammes.
l Utiliser exclusivement des fusibles ou coupe-circuits appropriés.
Ne pas augmenter leur puissance; ne pas les ponter.
l 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.
l Lire et comprendre les fiches de données de sécurité et les ins-
tructions du fabricant concernant les adhésifs, les revêtements,
les nettoyants, les consommables, les produits de refroidissement, les dégraisseurs, les flux et les métaux.
Le BRUIT peut endommager l’ouïe.
Le bruit des processus et des équipements peut
affecter l’ouïe.

2-7.Informations relatives aux CEM
Le courant électrique qui traverse tout conducteur génère des
champs électromagnétiques (CEM) à certains endroits. Le courant issu d’un soudage à l’arc (et de procédés connexes, y compris le soudage par points, le gougeage, le découpage plasma et les opérations
de chauffage par induction) crée un champ électromagnétique (CEM)
autour du circuit de soudage. Les champs électromagnétiques produits peuvent causer interférence à certains implants médicaux,
p. ex. les stimulateurs cardiaques. Des mesures de protection pour
les porteurs d’implants médicaux doivent être prises: par exemple,
des restrictions d’accès pour les passants ou une évaluation individuelle des risques pour les soudeurs. Tous les soudeurs doivent appliquer les procédures suivantes pour minimiser l’exposition aux CEM
provenant du circuit de soudage:
1. Rassembler les câbles en les torsadant ou en les attachant avec
du ruban adhésif ou avec une housse.
2. Ne pas se tenir au milieu des câbles de soudage. Disposer les câbles d’un côté et à distance de l’opérateur.
OM-291865 Page 10
3. Ne pas courber et ne pas entourer les câbles autour de votre
corps.
4. Maintenir la tête et le torse aussi loin que possible du matériel du
circuit de soudage.
5. Connecter la pince sur la pièce aussi près que possible de la
soudure.
6. Ne pas travailler à proximité d’une source de soudage, ni s’asseoir
ou se pencher dessus.
7. Ne pas souder tout en portant la source de soudage ou le
dévidoir.
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.

5-1.Moving The System
Use correct procedures and equipment of adequate capacity to lift
and support unit.
If using lift forks to move unit, be
sure forks are long enough to extend beyond opposite side of unit.
Keepequipment(cables and
cords) away from moving vehicles
when working from an aerial
location.
Use lifting eye to lift unit only, NOT
running gear, gas cylinders, or any
other accessories.
Miller Copilot is shipped in a crate capable of
being moved as a single unit. This not only
makes moving the system easy; it also
means a quick startup time once the machine is placed. Power, welding wire, and
welding gas are generally all that are required to have the system ready to program
and run production.
The cobot system and shipping crate weigh
less than 4500 pounds (1818 kg). An 8000
pound (3636 kg) capacity fork truck is recommended for safely moving and lifting the
system.

5-4.Electrical Service Guide
Failure to follow these electrical service guide recommendations could create an electric shock or fire hazard. These recommendations are for an individual branch circuit sized for the rated output and duty cycle of one welding power source. In individual
branch circuit installations, the National Electrical Code (NEC) allows the receptacle or conductor rating to be less than the rating
of the circuit protection device. All components of the circuit must be physically compatible. See NEC articles 210.21, 630.11, and
630.12.
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 generator with automatic idle device (that idles engine when no load is sensed) to supply input power to this welding power source.
NOTICE – Actual input voltage should not be 10% less than minimum and/or 10% more than maximum input voltages listed in table. If actual input voltage is outside this range, output may not be available.

2
3

The cobot system is operated from the front of the system using the operator station push buttons. In most cases welding operation only requires
the operator to load a part to be welded, press the “start” push button.
All personnel that will be operating the system must be familiar with the safety features of the system and know how to stop the
cobot in the case of an emergency.
8-1.Powering Up The System
1 Turn On disconnect power switch.
2 Turn On welder power switch.
3 Turn On cobot controller switch.
4 Wait until cobot standby light is On.
5 Turn On teach pendant power switch.
8-2.Logging In To The System
When you power up the system, you automatically be logged in as an Operator. The Operator level does not require a password. If you need to
change default settings, log in as an Administrator. See the Manipulator Owner’s Manual.
8-3.System Settings
A cobot system has many settings that are configured when the system is assembled. Most are one-time settings that will never need to be
changed for the life of the system. This section introduces a few key concepts for basic setup and operation. This is not a comprehensive list of
all the settings that each system has. Refer to the Manipulator Owner’s Manual for more detailed information.
You can view these settings when you are logged in as an Operator.
You can change some settings not related to safety if you are logged in as an Administrator.

A. Home Position
1 Move to Position Button
2 Save Button
Press and holding the Move to Position button to move the cobot to the defined Home
position.
The Home position is automatically inserted
as the first line of any new program.
The Home position can be updated by moving the cobot to a new Home position and
pressing the Save button.
It is a good practice when creating programs
to start and end programs at the Home position so operators can understand when the
cobot has completed a task.
B. Tool Center Point (TCP) Check
The TCP definition tells the cobot where the end of the torch is—the point where welding occurs (at least under ideal conditions). It is a reference
point that is used to control the motion of the cobot and to define the location of the wire tip in relation to the cobot's base or other reference
frame.
A pointer is mounted inside the system to be used as a quick reference to verify the torch and/or arm alignment. This can be a valuable tool to
determine if the welding torch is no longer in alignment because of a “crash” (when the torch or arm collides with something solid in the system
such as the tool, the part being welded, or the system frame).
To check the TCP using the reference pointer:
Step 1. Check the contact tip and replace it.
Step 2. Check the welding wire stick-out length (typically 12-15 mm) and straightness of the wire. Consistency is more important than how
straight the wire is; if the wire has a natural “cast” or bend, that is acceptable as long as the bend is consistent.
Step 3. Press the Move to Position button.
Step 4. Be prepared to stop the movement if the torch looks like it is going to crash with the TCP pointer.
Step 5. Move forward to the TCP Checkpoint.
Step 6. If the wire aligns with the pointer, TCP is confirmed and the system is ready for operation.
Step 7. If the wire does not align with the pointer, the torch may need straightening or adjustment, or it is possible that the cobot origin position is
no longer correct.
Step 8. If the wire aligns with the pointer but the part program is still not tracing or running correctly, the tool or parts to be welded may not be re-
peating correctly.
The position can be updated by moving the cobot to a new TCP position and pressing the Save button.
Be careful updating this position after you have created programs. Programs created before the revised TCP Check position may be shifted
based on an incorrect/damaged TCP point.

8-4.Inputs And Outputs
Cobot inputs and outputs are used to operate the system and understanding where to view these and what they mean can make running and
troubleshooting the system much easier.
To view the inputs and outputs go to Settings/IO Tab.
A. Cobot Inputs
Input signals from the different buttons and safety devices let the cobot know what operation to perform, and when it is safe for the cobot to start
moving. The following list covers the basic inputs to the cobot.

8-5.Auto Mode Start-Up
Once the weld programs have been created, follow the steps below to run the cobot automatically.
Option 1: Running the program Active in Teach
Step 1. Turn the operation box Auto/Teach key switch to Auto.
Step 2. Load and secure the part for welding.
Step 3. If cobot is not at first point in active program, Press and hold start button until cobot is at first point. Releasing button prior to reaching first
point will stop cobot.
Step 4. In case something is in the way of the cobot while moving to first position of program, switch Auto/Teach switch to teach and hand guide
cobot around obstacle and then switch back to Auto.
Step 5. Once cobot has reached first point in program. Press the START/PAUSE push button once. This will start the program.
Step 6. Pressing the start/pause button while the cobot is running the active program will cause the cobot to pause.
Step 7. Pressing the Start/Pause after the cobot has paused will resume the active program at the point it paused.
Step 8. Pressing the end program button while the cobot is running the active program will cause the cobot to stop and end the active program
Step 9. Pressing e-stop (or if the cobot generates an error while running the active program) will cause the cobot to stop and end the active
program.

SECTION 9 – TEACHING
Cobot systems are shipped with all the necessary system configuration installed so end users only need to program the welding that they want
the cobot to perform. This section makes recommendations and outlines the programming structure; this manual is not intended to instruct users
on the operation of the cobot teach pendant and explain the commands used in cobot programs. Please refer to the cobot operations manual for
specific information on using the teach pendant.
It is strongly recommended that new cobot users go through our basic operations training class before attempting to create or
modify programs on the cobot system. The cobot can potentially injure personnel or damage itself if not programmed properly.
9-1.Teach Mode
To teach new programs the cobot must be in Teach Mode. This means the key switch located on the operation box must be set to Teach.
Do not switch the Auto/Teach key switch while the cobot is actively running a program. If you wish to interrupt auto mode operation, press the
Start/Puse button first, then turn the key switch to Teach.
9-2.Pre-Teaching Checks
Any time an operator or programmer has an opportunity to inspect the system is a good time to look for normal wear that may need to be addressed. This is even more critical when a programmer is in the process of correcting a weld or creating a new program. Failure to check the cobot hardware before touching up points could result in lost time.
l Cobot torch alignment—crashes happen and many times no adjustment is needed but it is good programming practice to check the cobot
torch position against a fixed reference point to see if anything has moved since the last time the cobot was programmed. If it has, correcting
the hardware misalignment may solve any welding problems.
l Cables—the torch cable (whip), power cables, and liners sometimes get caught up on equipment. Twisted cables cause short circuits or bro-
ken wires. Welding wire liners forced to bend in a very small radius can keep wire from passing freely through the liner. Replace or service
any cable or liner that is visibly damaged or has reached the end of its useful service life.
