Welding current creates EMF fields around welding cables
and welding machines

2.b. EMF fields may interfere with some pacemakers, and
welders having a pacemaker should consult their physician
before welding.

2.c. Exposure to EMF fields in welding may have other health effects
which are now not known.

2.d. All welders should use the following procedures in order to
minimize exposure to EMF fields from the welding circuit:

2.d.1. Route the electrode and work cables together - Secure
them with tape when possible.

2.d.2. Never coil the electrode lead around your body.

2.d.3. Do not place your body between the electrode and work
cables. If the electrode cable is on your right side, the
work cable should also be on your right side.

2.d.4. Connect the work cable to the workpiece as close as pos­sible to the area being welded.

2.d.5. Do not work next to welding power source.

SAFETY

SAFETY

ELECTRIC SHOCK
CAN KILL.

3.a. The electrode and work (or ground) circuits are
electrically “hot” when the welder is on. Do
not touch these “hot” parts with your bare skin or wet clothing.
Wear dry, hole-free gloves to insulate hands.

3.b. Insulate yourself from work and ground using dry insulation.
Make certain the insulation is large enough to cover your full area
of physical contact with work and ground.

In addition to the normal safety precautions, if
welding must be performed under electrically
hazardous conditions (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, if there
is a high risk of unavoidable or accidental contact
with the workpiece or ground) use the following
equipment:

• Semiautomatic DC Constant Voltage (Wire) Welder.

• DC Manual (Stick) Welder.

• AC Welder with Reduced Voltage Control.

3.c. In semiautomatic or automatic wire welding, the electrode,
electrode reel, welding head, nozzle or semiautomatic welding
gun are also electrically “hot”.

3.d. Always be sure the work cable makes a good electrical
connection with the metal being welded. The connection should
be as close as possible to the area being welded.

3.e. Ground the work or metal to be welded to a good electrical (earth)
ground.

3.f. Maintain the electrode holder, work clamp, welding cable and
welding machine in good, safe operating condition. Replace
damaged insulation.

3.g. Never dip the electrode in water for cooling.

3.h. Never simultaneously touch electrically “hot” parts of electrode
holders connected to two welders because voltage

two can be the total of the open circuit voltage of both
welders.

3.i. When working above floor level, use a safety belt to protect
yourself from a fall should you get a shock.

3.j. Also see It ems 6.c. and 8.

ARC RAYS CAN BURN.

4.a. Use a shield with the proper filter and cover plates to protect your
eyes from sparks and the rays of the arc when welding or
observing open arc welding. Headshield and filter lens should
conform to ANSI Z87. I standards.

4.b. Use suitable clothing made from durable flame-resistant material
to protect your skin and that of your helpers from the arc rays.

4.c. Protect other nearby personnel with suitable, non-flammable
screening and/or warn them not to watch the arc nor expose
themselves to the arc rays or to hot spatter or metal.

FUMES AND GASES
CAN BE DANGEROUS.

5.a. Welding may produce fumes and gases
hazardous to health. Avoid breathing these
fumes and gases. When welding, keep your head out of the fume.
Use enough ventilation and/or exhaust at the arc to keep fumes
and gases away from the breathing zone. When welding

hardfacing (see instructions on container or SDS)
or on lead or cadmium plated steel and other
metals or coatings which produce highly toxic
fumes, keep exposure as low as possible and
within applicable OSHA PEL and ACGIH TLV limits
using local exhaust or mechanical ventilation
unless exposure assessments indicate otherwise.
In confined spaces or in some circumstances,
outdoors, a respirator may also be required.
Additional precautions are also required when
welding
on galvanized steel.

5. b. The operation of welding fume control equipment is affected by
various factors including proper use and positioning of the
equipment, maintenance of the equipment and the specific
welding procedure and application involved. Worker exposure
level should be checked upon installation and periodically
thereafter to be certain it is within applicable OSHA PEL and
ACGIH TLV limits.

5.c. Do not weld in locations near chlorinated hydrocarbon vapors
coming from degreasing, cleaning or spraying operations. The
heat and rays of the arc can react with solvent vapors to form
phosgene, a highly toxic gas, and other irritating products.

5.d. Shielding gases used for arc welding can displace air and

injury or death. Always use enough ventilation, especially in
confined areas, to insure breathing air is safe.

5.e. Read and understand the manufacturer’s instructions for this

equipment and the consumables to be used, including the
Safety Data Sheet (SDS) and follow your employer’s safety
practices. SDS forms are available from your welding
distributor or from the manufacturer.

WELDING AND CUTTING
SPARKS CAN CAUSE
FIRE OR EXPLOSION.

6.a. Remove fire hazards from the welding area. If
this is not possible, cover them to prevent the welding sparks
from starting a fire. Remember that welding sparks and hot
materials from welding can easily go through small cracks and
openings to adjacent areas. Avoid welding near hydraulic lines.
Have a fire extinguisher readily available.

6.b. Where compressed gases are to be used at the job site, special
precautions should be used to prevent hazardous situations.
Refer to “Safety in Welding and Cutting” (ANSI Standard Z49.1)
and the operating information for the equipment being used.

6.c. When not welding, make certain no part of the electrode circuit is
touching the work or ground. Accidental contact can cause
overheating and create a fire hazard.

6.d. Do not heat, cut or weld tanks, drums or containers until the
proper steps have been taken to insure that such procedures
will not cause flammable or toxic vapors from substances inside.
They can cause an explosion even though they have been
“cleaned”. For information, purchase “Recommended Safe
Practices for the Preparation for Welding and Cutting of
Containers and Piping That Have Held Hazardous Substances”,
AWS F4.1 from the American Welding Society
(see address above).

6.e. Vent hollow castings or containers before heating, cutting or
welding. They may explode.

6.f. Sparks and spatter are thrown from the welding arc. Wear oil free
protective garments such as leather gloves, heavy shirt, cuffless
trousers, high shoes and a cap over your hair. Wear ear plugs
when welding out of position or in confined places. Always wear
safety glasses with side shields when in a welding area.

6.g. Connect the work cable to the work as close to the welding area
as practical. Work cables connected to the building framework or
other locations away from the welding area increase the
possibility of the welding current passing through lifting chains,
crane cables or other alternate circuits. This can create fire
hazards or overheat lifting chains or cables until they fail.

6.h. Also see item 1.c.

6.I. Read and follow NFPA 51B “Standard for Fire Prevention During
Welding, Cutting and Other Hot Work”, available from NFPA, 1
Batterymarch Park, PO box 9101, Quincy, MA 022690-9101.

6.j. Do not use a welding power source for pipe thawing.

CYLINDER MAY EXPLODE IF
DAMAGED.

7.a. Use only compressed gas cylinders containing
the correct shielding gas for the process used
and properly operating regulators designed for
the gas and pressure used. All hoses, fittings,
etc. should be suitable for the application and
maintained in good condition.

7.b. Always keep cylinders in an upright position securely chained to
an undercarriage or fixed support.

7.c. Cylinders should be located:

• Away from areas where they may be struck or subjected
to physical damage.

• A safe distance from arc welding or cutting operations
and any other source of heat, sparks, or flame.

7.d. Never allow the electrode, electrode holder or any other
electrically “hot” parts to touch a cylinder.

7.e. Keep your head and face away from the cylinder valve outlet
when opening the cylinder valve.

7.f. Valve protection caps should always be in place and hand tight
except when the cylinder is in use or connected for use.

7.g. Read and follow the instructions on compressed gas cylinders,
associated equipment, and CGA publication P-l, “Precautions for
Safe Handling of Compressed Gases in Cylinders,” available from
the Compressed Gas Association, 14501 George Carter Way
Chantilly, VA 20151.

SAFETY

ELECTROMAGNETIC

COMPATIBILITY (EMC)

CONFORMANCE

Products displaying the CE mark are in conformity with European Community
Council Directive of 3 May 1989 on the approximation of the laws of the
Member States relating to electromagnetic compatibility (2014/30/UE). It
was manufactured in conformity with a national standard that implements a
harmonized standard: EN 60974-10

Electromagnetic Compatibility (EMC) Product Standard for Arc Welding
Equipment. It is for use with other Lincoln Electric equipment. It is designed

for industrial and professional use.

INTRODUCTION

All electrical equipment generates small amounts of electromagnetic
emission. Electrical emission may be transmitted through power lines or
radiated through space, similar to a radio transmitter. When emissions are
received by other equipment, electrical interference may result. Electrical
emissions may affect many kinds of electrical equipment; other nearby
welding equipment, radio and TV reception, numerical controlled machines,
telephone systems, computers, etc. Be aware that interference may result
and extra precautions may be required when a welding power source is used
in a domestic establishment.

INSTALLATION AND USE

The user is responsible for installing and using the welding equipment
according to the manufacturer’s instructions. If electromagnetic disturbances
are detected then it shall be the responsibility of the user of the welding
equipment to resolve the situation with the technical assistance of the
manufacturer. In some cases this remedial action may be as simple as
earthing (grounding) the welding circuit, see Note. In other cases it could
involve construction of an electromagnetic screen enclosing the power source
and the work complete with associated input filters. In all cases electro­magnetic disturbances must be reduced to the point where they are no longer
troublesome.

Note: The welding circuit may or may not be earthed for safety reasons according to national codes.
Changing the earthing arrangements should only be authorized by a person who is competent to
access whether the changes will increase the risk of injury, e.g., by allowing parallel welding current
return paths which may damage the earth circuits of other equipment.

ASSESSMENT OF AREA

Before installing welding equipment, the user shall make an assessment of
potential electromagnetic problems in the surrounding area. The following
shall be taken into account:

a. Other supply cables, control cables, signaling and telephone cables; above, below

and adjacent to the welding equipment;

b. radio and television transmitters and receivers;

c. computer and other control equipment;

d. safety critical equipment, e.g., guarding of industrial equipment;

e. the health of the people around, e.g., the use of pacemakers and hearing aids;

f. equipment used for calibration or measurement and

g. the immunity of other equipment in the environment. The user shall ensure that other

equipment being used in the environment is compatible. This may require additional
protection measures including:

h. the time of day that welding or other activities are to be carried out.

The size of the surrounding area to be considered will depend on the
structure of the building and other activities that are taking place. The
surrounding area may extend beyond the boundaries of the premises.

METHODS OF REDUCING EMISSIONS

Mains Supply

Welding equipment should be connected to the mains supply according
to the manufacturer’s recommendations. If interference occurs, it may be
necessary to take additional precautions such as filtering of the mains supply.
Consideration should be given to shielding the supply cable of permanently
installed welding equipment, in metallic conduit or equivalent. Shielding
should be electrically continuous throughout its length. The shielding should
be connected to the welding power source so that good electrical contact is
maintained between the conduit and the welding power source enclosure.

Maintenance of the Welding Equipment

The welding equipment should be routinely maintained according to the
manufacturer’s recommendations. All access and service doors and covers
should be closed and properly fastened when the welding equipment is in
operation. The welding equipment should not be modified in any way except
for those changes and adjustments covered in the manufacturers instructions.
In particular, the spark gaps of arc striking and stabilizing devices should be
adjusted and maintained according to the manufacturer’s recommendations.

Welding Cables

The welding cables should be kept as short as possible and should be
positioned close together, running at or close to floor level.

Equipotential Bonding

Bonding of all metallic components in the welding installation and adjacent
to it should be considered. However, metallic components bonded to the
work piece will increase the risk that the operator could receive a shock by
touching these metallic components and the electrode at the same time. The
operator should be insulated from all such bonded metallic components.

Earthing of the Workpiece

Where the workpiece is not bonded to earth for electrical safety, not
connected to earth because of its size and position, e.g., ships hull or
building steelwork, a connection bonding the workpiece to earth may reduce
emissions in some, but not all instances. Care should be taken to prevent the
earthing of the work piece increasing the risk of injury to users, or damage to
other electrical equipment. Where necessary, the connection of the workpiece
to earth should be made by a direct connection to the work piece, but in some
countries where direct connection is not permitted, the bonding should be
achieved by suitable capacitance, selected according to national regulations.

Screening and Shielding

Selective screening and shielding of other cables and equipment in the
surrounding area may alleviate problems of interference. Screening of the
entire welding installation may be considered for special applications.

APEX 30S System

Basic Information

The APEX
APEX 3 Series family of controllers and is the rst
of its kind that can be used for GMAW/FCAW and
GTAW welding.

Moving from at track, plate or other structural beams
to an orbital track takes only a simple weld head
adjustment. Synchronizing amps, volts, travel speed,
and oscillation, the APEX 30S controller can be utilized
for more welding applications than before.

The APEX 30S controller also reduces the need for
auxiliary components by incorporating a gas solenoid
and ow sensor within the controller, minimizing cable
clutter and reducing the overall footprint of the
congured system.

The status of APEX 30S controller can be monitored on

and 9 - System Assembly.

Note:

• Always use the shortest cable lengths possible.

DO NOT coil excess cable. It is recommended that
the total length of control cable does not exceed
100’ (30.5M). The use of non-standard cables in
excess of 25’ (7.5M) can lead to communication
problems (system shut downs), poor motor accelera­tion (poor arc starting), and low wire driving force
(wire feeding problems).

• Best results will be obtained when the control cables

are routed separate from the weld cables. This mini­mizes the possibility of interference between the
high currents owing through the weld cables and
the low level signals in the control cables.:

Cable List

1. Pendant Cable - Connects from the pendant to

the control unit

2. Control Cable - Connects from the weld head to
the control unit

3. Torch Assembly - Runs from the control unit
out to the weld head. Includes power, sense lead,

gas and water lines

4. Work Cable* - Connects from the POWER WAVE
unit (or Advanced Process Module if installed) to
the work piece

5. 3-Phase Power Cable* - Connects power supply

to facility power (refer to power supply manual for
installation)

6. Gas Hose* - Supplies gas to the system from

external source

7. Ethernet Cable* - Optional cable to connect the

power supply to a local area network for added
system functionality

* Indicates items not included with the system

ArcLink cables can be used to extend the pendant
cable length.

WARNING

CYLINDER MAY EXPLODE IF DAMAGED.

• Keep cylinder upright and chained to support.

• Keep cylinder away from areas where it may be damaged.

• Never lift welder with cylinder attached.

• Never allow welding electrode to touch cylinder.

• Keep cylinder away from welding or other live electrical circuits

•

THE BUILD UP OF SHIELDING GAS MAY HARM HEALTH OR KILL.

• Shut off shielding gas supply when not in use.

• See American National Standard Z-49.1,
“Safety in Welding and Cutting”

Published by the American Welding Society.

MAXIMUM INLET PRESSURE IS 100 PSI. (6.9 BAR.)

INSTALLATIONAPEX® 30S

.

Install the shielding gas supply as follows:

1. Secure the cylinder to prevent it from falling.

2. Remove the cylinder cap. Inspect the cylinder valves
and regulator for damaged threads, dirt, dust, oil or
grease. Remove dust and dirt with a clean cloth. DO

NOT ATTACH THE REGULATOR IF OIL, GREASE OR
DAMAGE IS PRESENT! Inform your gas supplier of this

condition.

3. Stand to one side away from the outlet and open the cyl­inder valve for an instant. This blows away any dust or dirt
which may have accumulated in the valve outlet.

4. Attach the flow regulator to the cylinder valve and tighten
the union nut(s) securely with a wrench.

Note: if connecting to 100 percent CO2 cylinder, insert
regulator adapter between regulator and cylinder valve.
If adapter is equipped with a plastic washer, be sure it is
seated for connection to the CO2 cylinder.

5. Attach one end of the inlet hose to the outlet fitting of the
flow regulator. Attach the other end to the welding system
shielding gas inlet. Tighten the union nuts with a wrench.

6. Before opening the cylinder valve, turn the regulator
adjusting knob counterclockwise until the adjusting spring
pressure is released.

7. Standing to one side, open the cylinder valve slowly a
fraction of a turn. When the cylinder pressure gage stops
moving, open the valve fully.

8. The flow regulator is adjustable. Adjust it to the flow rate
recommended for the procedure and process being used
before making a weld.

Maintenance

The APEX 30S Control is designed for trouble-free
operation and normally requires minimal preventive
care and cleaning. This section provides instructions
for maintaining user serviceable items. The suggested
repair procedure for all such items is to remove and
replace defective assemblies or parts. When users
and/or service personnel are not familiar with electrical
and electronic equipment, the product should be
returned to the factory or serviced by
factory authorized representatives.

Maintenance Schedule

The maintenance schedule is suggested as a
guideline for proper system maintenance. More
stringent maintenance requirements may be required
depending on the work being performed and the
requirements of the customer for whom the work is
performed. All maintenance schedules are based on
a 40-hour work week.

MAINTENANCE

Any excess play in parts or equipment should be
noted and reported to an authorized repair facility. Any
anomalous activity, such as motor hesitation, clicking
or other noises, or anything out of the ordinary should
be noted and reported to an authorized repair facility.

Every Shift

• Check lines, cables, and hoses for loose connections
and worn areas.

Monthly

• Examine all hose connections to verify that there
are no gas leaks. Make sure all cables are seated
correctly and that there is no visible wear and tear
to any connector or associated cables.

TROUBLE SHOOTING

Observe all Safety Guidelines detailed throughout this manual

Using the Status LED to Troubleshoot System Problems

The APEX 30S controller and the Power Wave unit are equipped with status LED. If a problem occurs, it is
important to note the condition of the status LED – see FIGURE 2 - Front Panel, item 5 on page B-1. Before
cycling power to the system, check the power source status LED for error sequences as noted below.

Included in this section is information about the Weld Head and ArcLink device status LEDs and a basic trouble­shooting chart for both the machine and the weld performance. The LEDs are dual-colored and indicate system
errors. Normal operation for each is steady green. Error conditions are indicated in FIGURE 10- Status LED

Light Conditions.

FIGURE 10 - Status LED Light Conditions

LIGHT CONDITION MEANING

Steady Green System is OK. The power source is operational and is communicating

normally with all peripheral equipment connected to its ArcLink device network.

Blinking Green Occurs during power up or a system reset and indicates the Power Wave unit is

mapped (identifying) each component in the system. This is normal for the rst
1 to 60 seconds after the power is turned on, or if the system conguration is
changed during operation.

Fast Blinking Green Under normal conditions it indicates that Auto-mapping has failed. It is also used

by Weld Manager Utilities. More information is available on the Service Navigator
CDs or visit www.powerwavesoftware.com.

Alternating Red and Green Non-recoverable system fault. If the status lights are ashing any combination of

red and green, errors are present. Read and note the error code(s) before turning
off the machine.

Error code interpretation through the status light is detailed in the service manu­al. Individual code digits are ashed in red with a long pause between digits. If
more than one code is present, the codes will be separated by a green light.
Only active error conditions are accessible through the status light.

Error codes can also be retrieved with the Weld Manager Utility, included on the
Service Navigator CDs. For the most updated error code log information, please
visit: www.powerwavesoftware.com.

To clear the active error(s), turn the power source off and back on to reset the
system.

Steady Red Not applicable.

Blinking Red Not applicable.

If for any reason you do not understand the test procedures or are unable to perform the tests/repairs safely, contact
your Local Lincoln Authorized Field Service Facility for technical troubleshooting assistance before you proceed.
