ELECTRIC AND
MAGNETIC FIELDS
may be dangerous
2.a. Electric current flowing through any conductor causes
localized Electric and Magnetic Fields (EMF). Welding
current creates EMF fields around welding cables and
welding machines
2.b. EMF fiel ds may inte rfere with some pacem akers, 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:
Route the electrode and work cables together - Secure
2.d.1.
them with tape when possible.
2.d.2. Never co il the elec trode 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.
___________________________________________________
1.g. To prevent accidentally starting gasoline engines while
turning the engine or welding generator during maintenance
work, disconnect the spark plug wires, distributor cap or
magneto wire as appropriate.
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.
ii
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.

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.

SAFETY PRECAUTIONS
WARNING
ELECTRIC SHOCK can kill.
• Disconnect input power by removing plug from receptacle before
working inside WIRE FEEDER
WELDERS (140, 180 MODELS).
Use only grounded receptacle. Do not touch electrically “hot” parts inside WIRE FEEDER
WELDERS (140, 180 MODELS).
• Have qualified personnel do the maintenance
and trouble shooting work.
-----------------------------------------------------------------------
ROUTINE MAINTENANCE
POWER SOURCE COMPARTMENT
No user serviceable parts inside! Do not attempt to
perform service in the power source (fixed) side of the
WIRE FEEDER WELDERS (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.
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.
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.
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 WIRE FEEDER WELDERS (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 WIRE FEEDER WELDERS (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 WIRE
FEEDER WELDERS (140, 180 MODELS) and does
not require user intervention. The fan continues to run
during cooling.
Electronic Wire Drive Motor Protection
The WIRE FEEDER WELDERS (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.
