SAFETY
ii
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
between the 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 Items 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. W elding 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 with electrodes which require special
ventilation such as stainless or hard facing (see
instructions on container or MSDS) 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. In confined spaces or in some circumstances, outdoors, a respirator may 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
coming from degreasing, cleaning or spraying operations.
The heat and rays of the arc can react with solvent vapors
form phosgene, a highly toxic gas, and other irritating products.
5.d. Shielding gases used for arc welding can displace air and
cause injury or death. Always use enough ventilation,
especially in confined areas, to insure breathing air is safe.

SAFETY
Electromagnetic Compatibility (EMC)
Conformance
Products displaying the CE mark are in conformity with European Community Council Directive of 15 Dec
2004 on the approximation of the laws of the Member States relating to electromagnetic compatibility,
2004/108/EC. 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.
iv
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
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;
h) the time of day that welding or other activities are to be carried out.

SAFETY
Electromagnetic Compatibility (EMC)
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.
v
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 workpiece
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 workpiece, but in some countries
where direct connection is not permitted, the bonding should be achieved by suitable capacitance, selected
according to national regulations.
OPERATORʼS MANUAL
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

PRODUCT DESCRIPTION (PRODUCT
CAPABILITIES)
These small portable wire feed welders are capable of
MIG welding on steel, stainless steel, and aluminum.
They are also capable of flux-cored welding on mild
steel.
MIG welding stands for Metal Inert Gas welding and
requires a separate bottle of shielding gas to protect
the weld until it cools. Appropriate shielding gas
based on the type of material you are welding can be
purchased separately from your local welding gas distributor. MIG welding is ideal for welding on thinner
and clean materials when a very clean excellent cosmetic looking weld is required. An example would be
automotive body panels.
Self Sheilding Flux-cored Welding does not require
separate shielding gas to protect the weld since the
welding wire has special additives known as flux to
protect the weld until it cools. Flux-cored welding is
ideal for medium to thicker material and if welding on
painted or rusty steel. Flux-cored welding is also ideal
in outdoor applications where windy conditions might
blow the MIG shielding gas away from the weld. Fluxcored welding produces a good looking weld but does
not produce an excellent weld appearance as MIG
welding does.
Your machine includes the necessary items to weld
with either the MIG or the flux-cored welding process
on steel. To weld on stainless steel optional stainless
steel welding wire can be purchased separately. This
machine can weld aluminum using .035”(0.9mm)
diameter 4043 aluminum welding wire. Since aluminum welding wire is soft an optional aluminum
spool gun is recommended for best results. A welding
Procedure Decal is located inside machine door to
help provide suggested settings for welding.

OPERATION
CONTROLS AND SETTINGS
This machine has the following controls:
(See Figure B.1)
1. POWER SWITCH – Turns power on and off to the
machine.
2. ARC VOLTAGE CONTROL – This knob sets the
output voltage of the machine. Along with wire feed
speed (WFS) this control sets a weld procedure.
Refer to the procedure decal on the inside wire
drive compartment door to set a correct welding
procedure based on type of material and thickness
being welded.
B-2
FIGURE B.1
3. WIRE FEED SPEED CONTROL (WFS) – The knob
sets the speed that the machine feeds wire. Along
with arc voltage this control sets a weld procedure.
Refer to the procedure decal on the inside wire
drive compartment door to set a correct welding
procedure based on type of material and thickness
being welded.
(See Figure B.2)
4. GUN TRIGGER – Pressing the trigger to activates
the wire drive to feed wire and energizes the output
of the machine. Depress the trigger to weld and
release the trigger to stop welding.
5. WELDING GUN – Delivers wire and welding cur-
rent to the weld.
a. Gun Liner – wire travels through the liner from
the wire drive. The gun liner will feed .025” to
.035” (0.6mm to 0.9mm) wire. The 180A
machine can weld with .045”(1.1mm) wire if an
optional .045”(1.1mm) liner is installed in the
gun.
b. Contact Tip – provides electrical contact to the
wire.
c. Nozzle – When flux-cored welding the black noz-
zle protects the mounting threads on the gun.
When MIG welding the copper nozzle funnels the
shielding gas to the weld.

SHIELDING GAS
1. Secure the cylinder to a wall or other stationary
support to prevent the cylinder from falling over.
Insulate the cylinder from the work circuit and earth
ground. Refer to Figure B.13.
2. With the cylinder securely installed, remove the
cylinder cap. Stand to one side away from the outlet and open the cylinder valve very slightly for an
instant. This blows away any dust or dirt which may
have accumulated in the valve outlet.
WARNING
BE SURE TO KEEP YOUR FACE AWAY FROM
THE VALVE OUTLET WHEN “CRACKING” THE
VALVE. Never stand directly in front of or behind
the flow regulator when opening the cylinder
valve. Always stand to one side.
-----------------------------------------------------------------------
1. For
CO2, open the cylinder very slowly. For argonmixed gas, open cylinder valve slowly a fraction of a
turn. When the cylinder pressure gauge pointer stops
moving, open the valve fully.
2. Set gas flow rate for 30 to 40 cubic feet per hour (14
to 18 I/min.) under normal conditions, increase to as
high as 40 to 50 CFH (18 to 23.5 I/min.) under drafty
(slightly windy) conditions.
3. Keep the cylinder valve closed, except when using
the machine.

perform service in the power source (fixed) side of the
POWER MIG® (140, 180 MODELS). Take the unit to
an authorized Lincoln Service Center if you experience problems. NO maintenance is required.
In extremely dusty locations, dirt may clog the air passages causing the welder to run hot with premature
tripping of thermal protection. If so, blow dirt out of the
welder with low pressure air at regular intervals to
eliminate excessive dirt and dust build-up on internal
parts.
GUN AND CABLE MAINTENANCE
FOR MAGNUM™ PRO 100L GUN
Gun Cable Cleaning
Clean cable liner after using approximately 300 lbs
(136 kg) of solid wire or 50 lbs (23 kg) of flux-cored
wire. Remove the cable from the wire feeder and lay it
out straight on the floor. Remove the contact tip from
the gun. Using low pressure air, gently blow out the
cable liner from the gas diffuser end.
CAUTION
Excessive pressure at the start may cause the dirt
to form a plug.
Flex the cable over its entire length and again blow
out the cable. Repeat this procedure until no further
dirt comes out.
Contact Tips, Nozzles, and Gun Tubes
1. Dirt can accumulate in the contact tip hole and
restrict wire feeding. After each spool of wire is
used, remove the contact tip and clean it by pushing a short piece of wire through the tip repeatedly.
Use the wire as a reamer to remove dirt that may
be adhering to the wall of the hole through the tip.
2. Replace worn contact tips as required. A variable
or “hunting” arc is a typical symptom of a worn contact tip. To install a new tip, choose the correct size
contact tip for the electrode being used (wire size is
stenciled on the side of the contact tip) and screw it
snugly into the gas diffuser.
3. Remove spatter from inside of gas nozzle and from
tip after each 10 minutes of arc time or as required.
OPERATORʼS MANUAL
WIRE FEED COMPARTMENT
1. When necessary, vacuum accumulated dirt from
gearbox and wire feed section.
2. Occasionally inspect the incoming guide tube and
clean inside diameter if necessary.
3. Motor and gearbox have lifetime lubrication and
require no maintenance.
FAN MOTOR
Has lifetime lubrication — requires no maintenance.
WIRE REEL SPINDLE
Requires no maintenance. Do not lubricate shaft.
POWER MIG® (140, 180 MODELS)
4. Be sure the gas nozzle is fully screwed onto the
diffuser for gas shielded processes. For the
Innershield®process, the gasless nozzle should
screw onto the diffuser.
5. To remove gun tube from gun, remove gas nozzle
or gasless nozzle and remove diffuser from gun
tube. Remove both collars from each end of the
gun handle and separate the handle halves.
Loosen the locking nut holding the gun tube in
place against the gun end cable connector.
Unscrew gun tube from cable connector. To install
gun tube, screw the locking nut on the gun tube as
far as possible. Then screw the gun tube into the
cable connector until it bottoms. Then unscrew (no
more than one turn) the gun tube until its axis is
perpendicular to the flat sides of the cable connector and pointed in the direction of the trigger.
Tighten the locking nut so as to maintain the proper
relationship between the gun tube and the cable
connector. Replace the gun handle, trigger and diffuser. Replace the gas nozzle or gasless nozzle.

MAINTENANCE
OVERLOAD PROTECTION
Output Overload
The POWER MIG® (140, 180 MODELS) is equipped
with a circuit breaker and a thermostat which protects
the machine from damage if maximum output is
exceeded. The circuit breaker button will extend out
when tripped. The circuit breaker must be manually
reset.
Thermal Protection
The POWER MIG® (140, 180 MODELS) has a rated
output duty cycle as defined in the Technical
Specification page. If the duty cycle is exceeded, a
thermal protector will shut off the output until the
machine cools to a reasonable operating temperature.
This is an automatic function of the POWER MIG®
(140, 180 MODELS) and does not require user intervention. The fan continues to run during cooling.
Electronic Wire Drive Motor Protection
The POWER MIG® (140, 180 MODELS) has built-in protection for wire drive motor overload.

CHANGING LINER
NOTICE: The variation in cable lengths prevents the
interchangeability of liners. Once a liner has been cut
for a particular gun, it should not be installed in another gun unless it can meet the liner cutoff length
requirement. Refer to Figure D.2.
1. Remove the gas nozzle from the gun by unscrewing counter-clockwise.
2. Remove the existing contact tip from the gun by
unscrewing counter-clockwise.
3. Remove the gas diffuser from the gun tube by
unscrewing counter-clockwise.
4. Lay the gun and cable out straight on a flat surface.
Loosen the set screw located in the brass connector at the wire feeder end of the cable. Pull the liner
out of the cable.
5. Insert a new untrimmed liner into the connector end
of the cable. Be sure the liner bushing is stenciled
appropriately for the wire size being used.
6. Fully seat the liner bushing into the connector.
Tighten the set screw on the brass cable connector.
At this time, the gas diffuser should not be installed
onto the end of the gun tube.
8. Screw the gas diffuser onto the end of the gun tube
and securely tighten.
9. Replace the contact tip and nozzle.
GUN HANDLE PARTS
The gun handle consists of two halves that are held
together with a collar on each end. To open up the
handle, turn the collars approximately 60 degrees
counter-clockwise until the collar reaches a stop. Then
pull the collar off the gun handle. If the collars are difficult to turn, position the gun handle against a corner,
place a screwdriver against the tab on the collar and
give the screwdriver a sharp blow to turn the collar
past an internal locking rib. See Figure D-3.

7. With the gas nozzle and diffuser removed from the
gun tube, be sure the cable is straight, and then
trim the liner to the length shown in the Figure D.2.
Remove any burrs from the end of the liner.
