LINCOLN ELECTRIC W000275408-2 Lincgun Promig Welding Gun

SAFETY INSTRUCTIONS

WARNING: This equipment have to be used by qualified personnel. Be sure that all installation, operation, maintenance and repair procedures are performed only by qualified person. Read and understand this manual before operating this equipment. Failure to follow the instructions in this manual could cause serious personal injury, loss of life, or equipment damage. Read and understand the following explanations of the warning symbols. Lincoln Electric is not responsible for damages caused by improper installation, improper care or abnormal operation.

• WARNING: This symbol indicates that instructions must be followed to avoid serious personal injury, loss of life, or equipment damage. Protect yourself and others from possible serious injury or death.
• READ AND UNDERSTAND INSTRUCTIONS: Read and understand this manual before operating this equipment. Arc welding can be hazardous. Failure to follow the instructions in this manual could cause serious personal injury, loss of life, or equipment damage. Before any internal verifications and repair work, make sure that the equipment is separated from the electric installation by electrical isolation (by electrical isolation is meant a group of operations designed
  to separate and keep the equipment de-energized).
• ELECTRIC SHOCK CAN KILL: Welding equipment generates high voltages. Do not touch the electrode, work clamp, or connected work pieces when this equipment is turned on. Insulate yourself from the electrode, work clamp, and connected work pieces.
• ELECTRICALLY POWERED EQUIPMENT: Regularly inspect the input, electrode, and work clamp cables. If any insulation damage exists replace the cable immediately. Do not place the electrode holder directly on the welding table or any other surface in contact with the work clamp to avoid the risk of accidental arc ignition. At least every six months, you must check the proper condition of the insulation and connections of the electric equipment and accessories
  such as plugs, flexible wires, ducts, connectors, extension leads, part holders, electrode-holders, or torches etc.
• ELECTROMAGNETIC FIELD MAY BE DANGEROUS: Electric current flowing through any conductor creates electromagnetic field (EMF). EMF fields may interfere with some pacemakers, and welders having a pacemaker shall consult their physician before operating his equipment.
  Never wrap the welding/cutting cable round your body or rest it on your shoulder;
• CE COMPLIANCE: This equipment complies with the European Community Directives.
• ARTIFICIAL OPTICAL RADIATION: According with the requirements in 2006/25/EC Directive and
  EN 12198 Standard, the equipment is a category 2. It makes mandatory the adoption of Personal Protective Equipment (PPE) having filter with a protection degree up to a maximum of 15, as required by EN169 Standard.
• FUMES AND GASES CAN BE DANGEROUS: Welding may produce fumes and gases hazardous to health. Avoid breathing these fumes and gases. To avoid these dangers the operator must use enough ventilation or exhaust to keep fumes and gases away from
  the breathing zone.
• ARC RAYS CAN BURN: 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. To protect the skin, use suitable clothing made of durable, fireproof material. Protect other nearby personnel with suitable, non-flammable screening and warn them not to watch the arc nor expose themselves to the arc.
• WELDING SPARKS CAN CAUSE FIRE OR EXPLOSION: Remove fire hazards from the welding area and have a fire extinguisher easily accessible. Welding sparks and hot materials from the welding process can easily go through small cracks and openings to adjacent areas. Do not weld on any tanks, drums, containers, or material until the proper steps have been taken to insure that no flammable or toxic vapors will be present. Never use this equipment when flammable gases, vapors or flammable liquids are present.
• WELDED MATERIALS CAN BURN: Welding generates a large amount of heat. Hot surfaces and materials in work area can cause serious burns. Use gloves and pliers when touching or moving materials in the work area.
• CYLINDER MAY EXPLODE IF DAMAGED: Use only certificate, compressed gas cylinders containing the correct shielding gas for the process used and properly operating regulators designed for the gas and pressure used. Always keep cylinders in an upright position securely chained to a fixed support. Do not move or transport gas cylinders with the protection cap removed. Do not allow the electrode, electrode holder, work clamp or any other electrically live part to touch a gas cylinder. Gas cylinders must be located away from areas where they may be subjected to physical damage or the welding process including sparks and heat sources.
• HOT COOLANT CAN BURN SKIN: Always be sure coolant is NOT HOT before servicing the cooler.

The manufacturer reserves the right to make changes and/or improvements in design without upgrade at the same time the operator’s manual.

GENERAL DESCRIPTION

The LINCGUN® PROMIG™ Amps guns have been designed to meet IEC 60974-7 specification for welding with steel electrode using the GMAW (gas metal arc welding) and gas-shielded FCAW (flux- cored arc welding) processes. LINCGUN® PROMIG™ guns are manually guided and air cooled or water cooled (models with “W”).

The LG PROMIG guns can be connected to the any feeder with EURO connector. For the best performance is recommended to use these guns with the Lincoln Electric welders, coolers and FREEZCOOL.

Please always use the original wear parts.

MAINTENANCE

Periodically remove and clean the nozzle, contact tip and gas diffuser. Replace the nozzle if damaged. Regular use of an antispatter compound will reduce the adherence of spatter and ease its removal. Clean cable liner after using approximately 140 kg of electrode. Remove the cable from the wire feeder and lay it out straight on the floor. 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.

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.
