Frequently Asked Questions - POWER MIG 180 Dual LINCOLN ELECTRIC

How do I change polarity for MIG or flux-cored welding?

For MIG welding, connect the short power cable from the wire feeder to the positive (+) terminal and the work cable to the negative (-) terminal. For flux-cored welding, reverse the connections: power cable to the negative (-) terminal and work cable to the positive (+) terminal. Refer to the procedure label on the machine door.

What should I do if the wire does not feed?

First check that the circuit breaker is not tripped and the switch is ON. Make sure the drive rolls are suitable for the wire diameter and the gun liner is not blocked. Also check that the internal wire guide is properly installed and the spool brake is correctly adjusted.

What gas should I use for MIG welding on mild steel?

For mild steel, use an Ar/CO2 (75/25) mix or 100% CO2. The mix gives a more stable arc and less spatter. Set the flow rate between 30 and 40 cubic feet per hour (14-18 l/min) in normal position.

How do I adjust voltage and wire speed?

Refer to the procedure label located inside the door of the wire feeder compartment. For a given thickness and wire type, first set the wire feed speed (WFS) then adjust the arc voltage accordingly. Adjust by trial until you get a stable arc and good bead appearance.

Why is the arc unstable?

Possible causes: incorrect input voltage, worn contact tip, inappropriate wire speed, or wrong polarity. Also check the cleanliness of the workpiece and the gas flow. If the problem persists, contact an authorized service center.

How do I clean the gun liner?

Remove the cable from the wire feeder and lay it straight. Remove the contact tip and gas diffuser. Gently blow low-pressure compressed air into the liner from the diffuser end. Bend the cable and repeat until no more dirt comes out. Perform this cleaning after about 300 lb (136 kg) of solid wire.

What should I do in case of overheating?

The machine is equipped with automatic thermal protection. If it activates, the indicator may light up and output is interrupted. Let the machine cool with the fan running. Reduce the duty cycle (continuous welding time) to avoid further overheating.

Can I weld aluminum with this machine?

Yes, with an optional spool gun (Magnum PRO 100SG) and 4043 aluminum wire 0.035 in (0.9 mm). Use 100% argon shielding gas and set the gun selector to Spool Gun. Follow the settings on the procedure label.

How do I install a new wire spool?

Place the spool on the spindle with the wire feeding off the top. Tighten the wing nut. Open the pressure arm, install the appropriate internal wire guide and drive roll for the wire size. Insert the wire into the drive, close the arm and adjust tension. Pull the trigger to feed wire through the liner until it comes out of the gun.

Where can I find replacement parts?

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 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 02 of 04 - 10/08/2021

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 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.

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.

1. 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 cause 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.
   5.f. Also see item 1.b.

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-I, "Precautions for Safe Handling of Compressed Gases in Cylinders," available from the Compressed Gas Association, 14501 George Carter Way Chantilly, VA 20151.

PRODUCT DESCRIPTION (PRODUCT CAPABILITIES)

This small portable wire feed welder is capable of MIG welding on steel, stainless steel, and aluminum. The wire feed welder is also capable of flux-cored welding on mild steel.

MIG welding stands for Metal Inert Gas welding and requires a 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 Shielding Flux-cored Welding does not require a 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. Flux-cored 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.

MAINTENANCE

SAFETY PRECAUTIONS

WARNING

ELECTRIC SHOCK can kill.

• Disconnect input power by removing plug from receptacle before working inside POWER MIG® 180 DUAL.
• Use only grounded receptacle. Do not touch electrically "hot" parts inside POWER MIG® 180 DUAL.
• 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 POWER MIG® 180 DUAL. 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.

OVERLOAD PROTECTION

Output Overload

The POWER MIG® 180 DUAL 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® 180 DUAL 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® 180 DUAL and does not require user intervention. The fan continues to run during cooling.

Electronic Wire Drive Motor Protection

The POWER MIG® 180 DUAL 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.1.

1. Remove the gas nozzle from the gun by unscrewing counterclockwise.
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.
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.1. Remove any burrs from the end of the liner.
8. Screw the gas diffuser onto the end of the gun tube and securely tighten.
9. Replace the contact tip and nozzle.

FIGURE D.1

1-1/4"(31.8 mm) Liner Trim Length Gas Diffuser Set Screw Brass Cable Connector Gas Nozzle or Gasless Nozzle Liner Assembly (liner bushing to be sealed tight against brass cable connector)

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.2.
