However, your overall safety can be increased by proper installation. And, most importantly, think before you act and be careful. Read and understand the following safety highlights. Clair Avenue, Cleveland, Ohio Wear dry, hole-free gloves to insulate hands. 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:.
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.
Maintain the electrode holder, work clamp, welding cable and welding machine in good, safe operating condition. Replace damaged insulation. When working above floor level, use a safety belt to protect yourself from a fall should you get a shock. 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. I standards.
Use suitable clothing made from durable flame-resistant material to protect your skin and that of your helpers from the arc rays. Welding may produce fumes and gases hazardous to health.
Avoid breathing these fumes and gases. When welding, keep your head out of the fume. 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 below Threshold Limit Values TLV 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. 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. 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. MSDS forms are available from your welding distributor or from the manufacturer. If this is not possible, cover them to prevent the welding sparks from starting a fire. Remember that welding sparks and hot. Avoid welding near hydraulic lines. Have a fire extinguisher readily available.
Where compressed gases are to be used at the job site, special precautions should be used to prevent hazardous situations. 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.
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. Vent hollow castings or containers before heating, cutting or welding. They may explode. 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. 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. All hoses, fittings, etc. Always keep cylinders in an upright position securely chained to an undercarriage or fixed support. Keep your head and face away from the cylinder valve outlet when opening the cylinder valve.
Valve protection caps should always be in place and hand tight except when the cylinder is in use or connected for use. Read and follow the instructions on compressed gas cylinders, associated equipment, and CGA publication P-l,. Turn off input power using the disconnect switch at the fuse box before working on the equipment. Install equipment in accordance with the U. Turn the engine off before troubleshooting and maintenance work unless the maintenance work requires it to be running.
Operate engines in open, well-ventilated areas or vent the engine exhaust fumes. Do not add the fuel near an open flame welding arc or when the engine is running. Stop the engine and allow it to cool before refueling to prevent spilled fuel from vaporizing on contact with hot engine parts and igniting.
Do not spill fuel when filling tank. If fuel is spilled, wipe it up and do not start engine until fumes have been eliminated. Keep all equipment safety guards, covers and devices in position and in good repair. Keep hands, hair, clothing and tools away from V-belts, gears, fans and all other moving parts when starting, operating or repairing equipment. In some cases it may be necessary to remove safety guards to perform required maintenance.
Remove guards only when necessary and replace them when the maintenance requiring their removal is complete. Do not put your hands near the engine fan. Do not attempt to override the governor or idler by pushing on the throttle control rods while the engine is running. 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.
To avoid scalding, do not remove the radiator pressure cap when the engine is hot. Welding current creates EMF fields around welding cables and welding machines. EMF fields may interfere with some pacemakers, and welders having a pacemaker should consult their physician before welding. Exposure to EMF fields in welding may have other health effects which are now not known. 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 them with tape when possible. 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. Connect the work cable to the workpiece as close as possible to the area being welded.

Before starting the installation, check with the local power company to determine if there is any question about whether your power supply is adequate for the voltage, amperes, phase, and frequency specified on the welder nameplate.
Also be sure the planned installation will meet the U. National Electrical Code and local code requirements. This welder may be operated from a single-phase line or from one phase of a three-phase line. Models that have multiple input voltages specified on the nameplate e. If the welder is to be operated at a lower voltage, it must be reconnected according to the instructions on the inside of the removable panel Reconnect Access Door near the top left side of the Case Back Assembly.
Also see the Reconnect Section of this manual for details on reconnecting the machine to operate at different voltages.
Be sure the voltage, phase, and frequency of the input power is as specified on the machine rating plate. See Figure A. Dirt, dust, or any foreign material that can be drawn into the machine should be kept at a minimum. Not following these precautions can result in the nuisance shutdown of the machine because of excessive operating temperatures. Protect the input circuit with the super lag fuses or delay type circuit breakers listed on the Specifications page of this manual for the machine being used.
The tripping action of delay type circuit breakers decreases as the magnitude of the current increases. DO NOT use fuses or circuit breakers with a lower amp rating than recommended. This can result in "nuisance" tripping caused by inrush current even when machine is not being used for welding at high output currents.
Use input and grounding wire sizes that meet local electrical codes or see the Specifications page in this manual. Use proper wire sizes. See the Specification table for proper wire sizes. For cable lengths over feet, larger copper wires should be used. Have a qualified electrician connect the receptacle or cable to the input power lines and the system ground according to the U. National Electrical Code and any applicable local codes. Use a single-phase line or one phase of a threephase line.
Mount the receptacle in a suitable location using the screws provided. Locate the receptacle within reach of the 10 ft. Mount the receptacle with the grounding terminal at the top. This allows the power cable to hang down without bending. The center terminal in the receptacle is for the grounding connection. Fuse the two hot lines of the receptacle with super lag type fuses as shown in Figure A.
A green wire in the input cord connects this terminal to the frame of the welder. This ensures. Refer to the specifications table at the beginning of this chapter for proper wiring sizes. For input power supply leads of 10 AWG or smaller, connect leads to Reconnect Panel using the ferrules S provided. Torque the terminal screws to 16 in. Customer must provide cylinder of appropriate type of shielding gas for gas metal arc welding for the process being used.
Set the gas cylinder on the rear platform of the SP Hook the chain in place to secure cylinder to rear of welder.
Inspect the cylinder valves for damaged threads, dirt, dust, oil or grease. Inform your gas supplier of this condition. Oil or grease in the presence of high pressure oxygen is explosive.
Stand to one side away from the outlet and open the cylinder valve for an instant to blow away any dust or dirt which may have accumulated in the valve outlet. Inspect the regulator for damaged threads, dirt, dust, oil or grease. Have an authorized repair station clean the regulator or repair any damage.
Attach the flow regulator to the cylinder valve and tighten the union nut s securely with a wrench. If adapter is equipped with a plastic washer, be sure it is seated properly to connect to the CO2 cylinder.
Connect one end of the inlet gas hose to the outlet fitting of the flow regulator. Connect the other end of the inlet gas hose to the SP rear fitting.
Tighten both the union nuts securely with a wrench. Lay the cable out straight. Make sure all pins on the gun cable connector are aligned with the proper mating sockets on the front panel gun connector and then join the connectors and tighten the hand nut on the gun cable connector.
The gun trigger switch must be capable of switching 5 milliamps at 15 volts DC resistive. The gun trigger switch connected to the gun trigger control cable must be a normally open momentary switch. The terminals of the switch must be insulated from the welding circuit. Improper operation of or damage to the SP might result if this switch is common to an electrical circuit other than the SP trigger circuit.
Always operate the welder with the hinged door closed and the side panels in place as these provide maximum protection from moving parts and insure proper cooling air flow. This unit combines a constant voltage power source, a constant speed wire feeder, and a microcomputer-based controller to form an intelligent welding system. A front panel touch key entry system with audible feedback, along with a two-line, 32 character alphanumeric display, provide user friendly control of the system.
The system provides full range control from the keypad or from the thumb switch built into the SP welding gun, which permits "on the fly" control while welding. Multi language display capability allows the SP to communicate with the user in any of the following five languages: English, German, French, Spanish, or Japanese Katakana.
Proper welding setup is simple. You only need to select the gauge size of the material to be welded and enter the welding process to used. With that data, the system. The system allows you to store up to five separate welding setup procedures. Wear dry, hole-free gloves to insulate hands. Ground the work or metal to be welded to a good electrical earth ground. Never dip the electrode in water for cooling. Also see Items 6. Also see item 1.
