SAFETY DEPENDS ON YOU

Lincoln arc welding and cutting equipment is designed and built with safety in mind. However, your overall safety can be increased by proper installation ... and thoughtful operation on your part. DO NOT INSTALL, OPERATE OR REPAIR THIS EQUIPMENT WITHOUT READING THIS MANUAL AND THE SAFETY PRECAUTIONS CONTAINED THROUGHOUT. And, most importantly, think before you act and be careful. This statement appears where the information must be followed exactly to avoid serious personal injury or loss of life. This statement appears where the information must be followed to avoid minor personal injury or damage to this equipment. KEEP YOUR HEAD OUT OF THE FUMES. DON’T get too close to the arc. Use corrective lenses if necessary to stay a reasonable distance away from the arc. READ and obey the Safety Data Sheet (SDS) and the warning label that appears on all containers of welding materials. USE ENOUGH VENTILATION or exhaust at the arc, or both, to keep the fumes and gases from your breathing zone and the general area. IN A LARGE ROOM OR OUTDOORS, natural ventilation may be adequate if you keep your head out of the fumes (See below). USE NATURAL DRAFTS or fans to keep the fumes away from your face. If you de velop unusual symptoms, see your supervisor. Perhaps the welding atmosphere and ventilation system should be checked.

WEAR CORRECT EYE, EAR &

BODY PROTECTION PROTECT your eyes and face with welding helmet properly fitted and with proper grade of filter plate (See ANSI Z49.1). PROTECT your body from welding spatter and arc flash with protective clothing including woolen clothing, flame-proof apron and gloves, leather leggings, and high boots. PROTECT others from splatter, flash, and glare with protective screens or barriers. IN SOME AREAS, protection from noise may be appropriate. BE SURE protective equipment is in good condition. Also, wear safety glasses in work area AT ALL TIMES. SPECIAL SITUATIONS DO NOT WELD OR CUT containers or materials which previously had been in contact with hazardous substances unless they are properly cleaned. This is extremely dangerous. DO NOT WELD OR CUT painted or plated parts unless special precautions with ventilation have been taken. They can release highly toxic fumes or gases. Additional precautionary measures PROTECT compressed gas cylinders from excessive heat, mechanical shocks, and arcs; fasten cylinders so they cannot fall. BE SURE cylinders are never grounded or part of an electrical circuit. REMOVE all potential fire hazards from welding area.

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:

• 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.

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 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. SAFETY Safety 03 of 04 - 10/08/2021WELDING AND CUTTING

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.

may harm health or kill. Shut off shielding gas supply when not in use.

OUTPUT POLARITY CONNECTIONS

The welding machine features a short lead protruding from the front of the machine, the lead can be used to congure the wire drive polarity. For STICK welding the short lead does not need to be connected and this lead will not be electrically hot. For FCAW, MIG, and TIG welding this lead can be connected to either the positive output stud or negative output stud. Connecting the lead to the positive stud will electrically connect the wire drive to positive polarity; the work clamp would then connect to the negative stud. Ensure connector is tightly locked into place by rotating clockwise.

1. Turn off the power source.

2. Release the pressure on the idle roll by swinging the

adjustable pressure arm down toward the back of the machine, allowing the tensioner to spring open.

3. Remove the drive roll retaining hand screw by turning counter

clockwise and remove the drive roll.

4. Remove and reinstall the drive roll based on wire to be used.

NOTE: be sure that the gun liner and contact tip are also sized to match the selected wire size.

5. Manually feed the wire from the wire reel, through the wire

guide, over the drive roll groove, and into the back of the gun adapter and gun and cable assembly.

6. Swing the tensioner back onto the wire and reposition the

adjustable pressure arm to its original position to apply pressure. Adjust pressure as necessary. FIGURE B.5 POWER-UP SEQUENCE

1. Check that the electrode polarity is correct for the process

being used. Refer to the quick start guide for polarity. Then turn the power switch ON. The fans will come on and stay on until power to the machine is removed.

2. Congure the machine for the desired process and

application. Use the Process Selection Button to select the desired welding process (WIRE, STICK, TIG). Use the adjustment knobs to set the parameters specied by the Procedure Decal for your desired welding condition.

3. If you are running a WIRE process, remove the contact tip,

then feed the wire through the liner to the gun tip. Replace the contact tip then cut the wire within approximately 3/8” (10 mm) from the end of the contact tip.

4. If shielding gas is to be used, turn on the gas supply and set

the gas to the required ow rate as specied by the Procedure Decal located on the door.

5. When using an Innershield electrode, the gas nozzle may be

removed and replaced with the gasless nozzle. This will provide increased visibility and eliminate the possibility of the gas nozzle overheating.

6. Connect the work cable to the metal to be welded. The work

clamp must make a good electrical contact with the piece being welded. The work must also be grounded as stated in “Arc Welding Safety Precautions.” For additional output ratings reference the rating plate present on the back of the machine. The duty cycle is the “on” time (based on a 10 minute interval) the user can weld with the machine at a specic output without causing a thermal trip. Example: 60% duty cycle means welding at a specied output for 6 constant minutes and needing 4 minutes of “off” time before welding again. If the duty cycle of the machine is exceeded, then the machine will thermally trip and the Thermal LED will Illuminate. The machine must cool down before welding can be performed.

Procedure for TIG welding with a Foot Pedal TIG welding with a foot pedal requires a Lincoln Electric K1782-16 Ready to Weld TIG Torch, a K4361-1 Foot Pedal and a bottle of 100% Argon Shielding Gas. The foot pedal permits the output current to be adjusted while welding. The foot pedal can be used to initiate the welding output and the ow of argon shielding gas. The machine will automatically detect when the foot pedal is connected and set the machine to TIG mode. Connect the Items to the machine as shown below FIGURE B.6 The welding arc current will be determined by the position of the foot pedal and the position of the V/A dial present on the front of the machine. In order to achieve maximum output, the V/A dial must be set to the letter “J” position and the foot pedal must be fully closed. Lower outputs can be achieved by reducing the V/A dial or by reducing the pressure on the foot pedal. To start the welding arc, lightly touch the tungsten to the piece that is to be welded and then press the foot pedal. Slowly pull or rock the tungsten off the work piece and the welding arc will initiate. After the foot pedal is released the shielding gas will continue to ow for 8 seconds. This post ow period is used to prevent contam- ination to the tungsten while the tungsten is still warm and to prevent contamination of the weld puddle. Procedure for TIG welding without a Foot Pedal FIGURE B.7 The welding output current will be determined by the position of the V/A dial present on the front of the machine. To start the welding arc, lightly touch the tungsten to the piece that is to be welded and keep the tungsten on the work piece for about 1 second to initiate the Argon shielding gas. Slowly pull or rock the tungsten off the work piece and the welding arc will initiate. After welding is complete the shielding gas will continue to ow for 8 seconds. This post ow period is used to prevent contamination to the tungsten while the tungsten is still warm and to prevent conta- mination of the weld puddle.

Use Personal Protective Equipment (PPE), including safety glasses, dust mask and gloves to avoid injury. This also applies to persons who enter the work area. MOVING PARTS can injure.

• Do not operate with doors open or guards off.

• Stop engine before servicing.

• Keep away from moving parts. Have qualied personnel do all maintenance and troubleshooting work. GENERAL MAINTENANCE In extremely dusty locations, dirt may clog the air passages causing the welder to run hot. Blow dirt out of the welder with low-pressure air at regular intervals to eliminate excessive dirt and dust build-up on internal parts. The fan motor has a sealed bearing, which requires no service

DRIVE ROLLS AND GUIDE PLATES

After every coil of wire, inspect the wire drive mechanism. Clean it as necessary by blowing with low pressure compressed air. Do not use solvents for cleaning the idle roll because it may wash the lubricant out of the bearing. All drive rolls are stamped with the wire sizes they will feed. If a wire size other than that stamped on the roll is used, the drive roll must be changed.

GUN TUBES AND NOZZLES

1. Replace worn contact tips as required.

2. Remove spatter from inside of gas nozzle and from tip after

each 10 minutes of arc time or as required.

To help prevent feeding problems, clean cable liner after using approximately 30 pounds (13.6 kg) of electrode. Remove the cable from the wire feeder and lay it out straight on the oor. Remove the contact tip from the gun. Using an air hose and only partial pressure, gently blow out the cable liner from the gas diffuser end. Excessive pressure at the beginning of the cleaning procedure 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. If this has been done and feed problems are experienced, replace the liner. PERIODIC MAINTENANCE

NOTE: The variation in cable lengths prevents interchanging of liners between guns. 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.

1. Remove the gas nozzle from the gun by unscrewing counter-

2. Remove the contact tip from the gun by unscrewing counter-

3. Remove the gas diffuser from the gun tube by unscrewing

4. Lay the gun and cable out straight on a at surface. Loosen

the set screw located in the brass connector that connects to the wire feeder. See bottom image. 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. Remove any burrs from the end of the liner.

diffuser onto the end of the gun tube and securely tighten.

9. Replace the contact

tip and nozzle. WARNING CAUTION
