INSTRUCTIONS for F-4644-M October, 2000 W-17 Welding Torch P/N 4250 These INSTRUCTIONS are for experienced operators. If you are not fully familiar with the principles of operation and safe practices for oxy-fuel gas equipment, we urge you to read our booklet Precautions and Safe Practices for Gas Welding, Cutting and Heating Form 2035. Do NOT permit untrained persons to install, operate, or maintain this equipment. Do NOT attempt to install or operate this equipment until you have read and fully understand these instructions. If you do not fully understand these instructions, contact your supplier for further information. The welding torch covered by these instructions is listed by Underwriters Laboratories only when used in combina- tion with welding tips and parts manufactured by ESAB Welding & Cutting Products to the specifications on file with Underwriters Laboratories, Inc., and when they are used in the gas services for which they are designed and listed. The use of other parts that cause damage or failure to the equipment will void the manufacturers warranty. SPECIFICATIONS Welding Range ........................ This gauge to over 1-in. Heating Range .......................... 1 to 250 cfh acetylene* Length ............................................................... 7-1/2-in. Weight ..................................................................... 1 lb. Torch-Hose Connections ................ Oxy - 9/16 - 18 fem. F.G. - 9/16 - 18 LH fem. * Equivalent to approximately 1400 to 370,000 Btu/hr. Acetylene and other fuel gases may be used. OPERATING INSTRUCTIONS CONNECTING 1. Attach regulators to the oxygen and acetylene cyl- inders. Follow all instructions supplied with your regulators. 2. Attach oxygen and acetylene hoses to the regula- tors and to the torch handle, after making sure all metal seating surfaces are clean. Tighten all con- nection nuts with a wrench. 3. Attach welding or heating head to the torch handle. Tighten the connection nut with a wrench, but use only slight force, since the threads have a low pitch and excessive force may distort them. 4. Check throttle valve packing nuts for tightness. Flashbacks can cause serious burns. Be sure gas flow is sufficient for head or nozzle size. Adjust regulators for proper psig pressures. Adjust throttle valves properly. Keep torch in good repair. DO NOT throttle back gases to use large head or nozzle on thin material. LIGHTING AND FLAME ADJUSTMENT 1. Open the torch oxygen valve one-quarter of a turn. 2. Open the torch fuel gas valve one-half turn (two full turns if low-pressure acetylene is being used) and light the gas at the tip with a friction lighter. DO NOT USE A MATCH. Use of a match can seriously burn your hand. 3. Open the oxygen valve wide and adjust the fuel gas valve to secure the desired flame. If a softer flame is desired, reduce the oxygen flow by throttling the oxygen valve and then readjust the fuel gas valve. NOTE: When operating with a very soft flame, the welding head will tend to heat up and transfer some of this heat to the torch handle. This may create some discomfort to the operator. Be sure this information reaches the operator. You can get extra copies through your supplier.

These Safety Precautions are for your protection. They sum-marize precautionary information from the references listedin Additional Safety Information section. Before performing anyinstallation or operating procedures, be sure to read and fol-low the safety precautions listed below as well as all othermanuals, material safety data sheets, labels, etc. Failure to ob-serve Safety Precautions can result in injury or death.

PROTECT YOURSELF AND OTHERS - Somewelding, cutting and gouging processes arenoisy and require ear protection. Hot metal cancause skin burns and heat rays may injureeyes. Training in the proper use of the pro-cesses and equipment is essential to preventaccidents. Also:

1. Always wear safety glasses with side shields in any work area,even if welding helmets, face shields, or goggles are also re-quired.

2. Wear flameproof gauntlet type gloves, heavy long-sleeve shirt,cuffless trousers, high-topped shoes, and a welding helmet orcap for hair protection, to protect against hot sparks and hotmetal. A flameproof apron may also be desirable as protectionagainst radiated heat and sparks.

3. Hot sparks or metal can lodge in rolled up sleeves, trouserscuffs, or pockets. Sleeves and collars should be kept buttoned,and open pockets eliminated from the front of clothing.

4. Protect other personnel from hot sparks with a suitable non-flammable partition or curtains.

5. Use goggles over safety glasses when chipping slag or grind-ing. Chipped slag may be hot and can travel considerable dis-tances. Bystanders should also wear goggles over safetyglasses.

FIRES AND EXPLOSIONS - Heat from a flamecan act as an ignition source. Hot slag or sparkscan also cause fires or explosions. Therefore:

1. Remove all combustible materials well away from the workarea or completely cover the materials with a protective non-flammable covering. Combustible materials include wood,cloth, sawdust, liquid and gas fuels, solvents, paints and coat-ings, paper, etc.

2. Hot sparks or hot metal can fall through cracks or crevices infloors or wall openings and cause a hidden smoldering fire onthe floor below. Make certain that such openings are protectedfrom hot sparks and metal.

3. Do not weld, cut, or perform any other hot work on materials,containers, or piping until it has been completely cleaned sothat no substances on the material can produce flammable ortoxic vapors. Do not do hot work on closed containers. Theymay explode.

4. Have fire extinguishing equipment handy for instant use, suchas a garden hose, a pail of water or sand, or portable fireextinguisher. Be sure you are trained in its use.

5. After completing operations, inspect the work area to be surethat there are no hot sparks or hot metal which could cause alater fire. Use fire watchers when necessary.

6. For additional information, refer to NFPA Standard 51B, “FirePrevention in Use of Cutting and Welding Processes”, whichis available from the National Fire Protection Association,Batterymarch Park, Quincy, MA 02269.

FUMES AND GASES - Fumes and gases, par-ticularly in confined spaces, can cause dis-comfort or injury. Do not breathe fumes orgases from welding or cutting, Therefore:

1. Always provide adequate ventilation in the work area by natu-ral or mechanical ventilation means. Do not weld, cut, or gougeon materials such as galvanized steel, stainless steel, copper,zinc, lead, beryllium, or cadmium unless positive mechanicalventilation is provided. Do not breathe fumes and gases fromthese materials.

2. If you develop momentary eye, nose, or throat irritation whileoperating, this is an indication that ventilation is not adequate.Stop work at once and take necessary steps to improve venti-lation in the work area. Do not continue to operate if physicaldiscomfort persists.

3. Refer to ANSI/ASC Standard Z49.1 listed below for specificventilation recommendations.

4. WARNING: This product, when used for welding orcutting, produces fumes or gases whichcontain chemicals known to the State ofCalifornia to cause birth defects and, insome cases, cancer. (California Health &Safety Code §25249.5 et seq.)

EQUIPMENT MAINTENANCE - Faulty or improperlymaintained equipment, such as torches, hoses andregulators, can result in poor work, but even moreimportant, it can cause injury or death through fires.Therefore:

1. Always have qualified personnel perform the installation,troubleshooting, and maintenance work. Do not operate orrepair any equipment unless you are qualified to do so.

2. Keep all oxy-fuel equipment free of grease or oil. Grease, oil,and other similar combustible materials, when ignited, can burnviolently in the presence of oxygen.

3. Do not abuse any equipment or accessories. Keep equipmentaway from heat and wet conditions, oil or grease, corrosiveatmospheres and inclement weather.

4. Keep all safety devices in position and in good repair.5. Use equipment for its intended purpose. Do not modify it in

any manner.

GAS CYLINDER HANDLING - Gas cylinders, if mis-handled, can rupture or explode violently. Suddenrupture of a cylinder, valve or relief device can in-jure or kill you. Therefore:

1. Use the proper gas for the process and use the proper pres-sure reducing regulator designed to operate from the com-pressed gas cylinder. Do not use adaptors to mount the regu-lator on the cylinder. Maintain hoses and fittings in good con-dition. Follow manufacturer’s operating instructions for mount-ing the regulator to the gas cylinder.

2. Always secure cylinders in an upright position by chain or strapto suitable hand trucks, benches, walls, post, or racks. Neversecure cylinders to work tables or fixtures where they maybecome part of an electrical circuit.

3. When not in use, keep cylinder valves closed. Have the valveprotection cap in place on top of the cylinder if no regulators isinstalled. Secure and move cylinders by using suitable handtrucks. Avoid rough handling of cylinders.

4. Locate cylinders away from heat, sparks, or flame of a weld-ing, cutting, or gouging operation. Never strike an arc on acylinder.

5. For additional information, refer to CGA Standard P-1, “Pre-cautions for Safe Handling of Compressed Gases in Cylin-ders:, which is available from the Compressed Gas Associa-tion, 1235 Jefferson Davis Highway, Arlington, VA 22202.

any doubt about the adequacy of gas flows, use anoxygen test gauge adaptor (P/N 07X17) and eitherthe acetylene (P/N 262510) or fuel gas (P/N 639422)test gauge adaptor while the torch is operating tomake sure that the recommended operating pres-sures are available at the torch inlet.

7. Manifold two or more fuel gas cylinders to assureadequate supply of fuel gas. The tables show thenumber of commonly used cylinders recommendedfor manifolding when using larger heads. If usingother cylinders or gases, check with your fuel gassupplier for recommended withdrawal rate informa-tion.

8. In the event of a flashback, immediately close bothoxygen and fuel gas valves on the torch (preferablyoxygen valve first). For greater protection, install1/4-turn quick shut off valve (P/N 999306) on thetorch oxygen hose connection.

** Based on max. continuous withdrawal rate of 65 cfh for 100 lb. cylinder,1/2 full @ 70° F.Withdrawal rate will increase with wind velocity and intermittent usage;reduce with lower temperature.

9. If the inner cone of the flame appears too short(less than 1/4-in.), you are lacking fuel gas and thehead will tend to overheat. Recheck the aboveprecaution with your set up.

10. Do not bring the head too close to the work. Maintaina distance of at least 1/4-in. between tip and work.

RECOMMENDED HOSE SIZES

Oxygen, Acetylene (medium-pressure) and NaturalGas (at pipeline pressure over 5 psig): With headsizes 4-30, 1/4-in. or 3/8-in. I.D. With head sizes 55 andlarger, 3/8-in I.D.

Acetylene (low-pressure) and Natural Gas (at pipe-line pressure below 5 psi): With head sizes 4-70, 3/8-in. I.D. hose. Head sizes 100-250, 1/2-in. hose. Donot use over 25 feet of hose.

SHUTTING OFFClose the fuel gas valve first, then the oxygen valve.

If operations are to be stopped for a half-hour or more,all pressure should be released from the torch hoses,and regulators by doing the following:

1. Close each cylinder or station valve.2. Open torch valves.3. After relieving the gases, back out the pressure-

adjusting screw of each regulator and close thetorch valves.

IMPORTANT OPERATING NOTES

1. Do not attempt to operate heads size 100 or largerfrom a low-pressure acetylene supply (less than 5psig).

2. Head size number of each welding and heatinghead indicates the rated acetylene capacity incubic feet/hour (cfh). For example, No. 55A re-quires about 55 cfh of acetylene at normal operat-ing pressure. However, on heating heads designedfor other fuel gases, the size indicates the approxi-mate equivalent heating capacity in terms of acety-lene flow. For example, No. 100A and No. 100FGprovide the same average heating output (147,000Btu/hr) but No. 100FG head really requires about62 cfh of FG-2, 57 cfh of propane, or 147 cfh ofnatural gas.

For consumption purposes, the following are the oxy-gen/fuel gas ratios normally required for welding andheating:1.1 to 1.5 cfh oxygen/1.0 cfh acetylene3.2 to 3.6 cfh oxygen/1.0 cfh FG-23.5 to 4.5 cfh oxygen/1.0 cfh propane1.7 to 2.0 cfh oxygen/1.0 cfh natural gas.

PRECAUTIONS - NO. 55 and LARGER HEADSLarge welding and heating heads (No. 55 and above)require high flow of oxygen and fuel gas for properoperation. Failure to follow the following precau-tions can result in serious overheating, flashback,and possible operator injury.

1. Read and understand the operating instructionspacked with your torch as well as these precautionsbefore lighting up the welding or heating head.

2. Always operate with oxygen and fuel gas pressuresgiven in the tables.

3. Do NOT use hose line reverse flow check valveswhen using No. 100 or larger welding or heatinghead.

4. Use 3/8-in. I.D. hoses when using No. 55 or largerwelding or heating head.

5. Do NOT use whip hose, hose splices, nor hosenipples smaller than 1/4-in. I.D. (“B”-size).

6. If using hose lengths greater than 25-ft., or if there is

TESTING FOR LEAKS

Every welding and cutting outfit should be thoroughlytested for leaks after it is first hooked up, and at regularintervals thereafter. After all connections have beenmade, make sure both valves on the torch handle areclosed. Then turn in the regulator pressure-adjustingscrew until the oxygen delivery-pressure gauge regis-ters 50 psi, the acetylene delivery-pressure gaugeregisters 10 psi. Using Leak Test Solution suitable foroxygen service, such as P/N 998771 (8 oz. container),check for leaks at the cylinder valves, the cylinder-to-regulator connections, the regulator-to-hose connec-tions, and the hose-to-torch connections. If bubbling atany point indicates leakage, tighten the connection. Ifthis does not stop the leakage, close the appropriatecylinder valve, open the torch valve to remove allpressure from the line, and finally release the regulatorpressure-adjusting screw by turning it counterclock-wise. Then break the leaky connection, wipe metalseating surfaces with a clean, dry cloth, and examinethem for nicks and scratches. Remake the connection(s)and retest. Do not try to light the torch until you aresatisfied that all connections are gas-tight.

After lighting the torch, and adjusting the flames, useleak test solution to check for leakage at all torch valves,and at the connection between the torch handle and thewelding head or cutting attachment.

OPERATING PRECAUTIONS

Flow: There must be proper flow of gases for safeoperation and full performance. This requires the fol-lowing three conditions: (1) the regulators that deter-mine the inlet pressure to the hoses must be set to thecorrect pressure: (2) the hoses and their connectorsmust have adequate capacity for the job (hoses that

are too long, too small or have connectors with smallpassageways can cause problems); and (3) the throttlevalves on the torch must be adjusted with the proce-dure shown in these instructions.

Note: Items (1) and (2) can be checked by measuringthe gas pressures at the torch. Gauge adaptorsare available for this purpose.

Backfire: Improper operation of the torch may causethe flame to go out with a loud ‘pop’. Such a backfiremay be caused by contact of the tip with the work,spatter from the tip, or by attempting to operate with toosmall a flame. After a backfire, you can normally relightthe flame immediately. If backfires occur repeatedly,shut off the torch. Then reopen the oxygen valve,check for correct oxygen pressure, and test for leak-age at the welding head connection nut and tip connec-tion nut. If there is leakage at either point, correct it (bytightening the tip, or cleaning the seating surfaces onthe injector and in the torch body) before resumingwork.

Flashback: Under certain circumstances, the flamemay not ‘pop’ out (backfire) but instead burn back insidethe torch with a shrill hissing or squeal. This is called a‘flashback’. A flashback should never occur if (1) theequipment is in good condition; (2) preheat ports oncutting nozzles or welding tips are cleaned frequently;(3) operating pressures are correct; and (4) throttlevalves are adjusted properly. Should a flashback occur,IMMEDIATELY shut off the torch. Allow it to cool off forat least a minute. Then check your nozzle or tip, gaspressure, readjust regulators if necessary, and relightthe torch. If flashback recurs, send the torch handle andwelding head or cutting attachment to ESABRemanufacturing Center or to your distributor for re-pair.

MAINTENANCE INSTRUCTIONS

For all repairs other than those covered below,send the apparatus to your welding equipmentdistributor or to ESAB Remanufacturing Center,Ebenezer Road, Florence, SC 29501. Improperlyrepaired apparatus is hazardous.

Torch Valves: Leakage around either throttle valvecan usually be corrected by tightening the packing nutslightly. If it cannot be corrected, replace throttle valveassembly.

If either valve fails to shut off completely, remove thethrottle valve assembly from torch and wipe the ballseat on the end of the stem with a clean cloth. Thenreinstall the valve and tighten it heavily several times. Ifthis does not eliminate leakage, try a new throttle valveassembly. If then the valve does not shut off completely,send the torch handle to a repair station for reseating ofthe body.

Tip Cleaning: If a welding tip produces a distorted,irregular flame, clean the tip with an OXWELD tipcleaner, or the correct size twist drill (see table on page4). Do not attempt to clean with any other type of tool.When using cleaning drills, push the drill straight in andout; do not twist.

Injector Cleaning: The relative small central oxygenorifice in an injector may become partially clogged withsmall particles conveyed in the oxygen stream orcarbon particles produced by backfires. To clean orreplace an injector, remove it from the mixer tube (afterremoving the connection nut retaining ring and slidingthe nut forward) by grasping it with a pair of pliersbetween the seating surfaces and pulling it straight outwith steady force. Take great care not to mar theinjector seats or O-rings with the pliers. Clean thecentral (oxygen) orifice with the correct size twist drill(see table on page 4). Use no other tools. Replace O-rings if damaged or worn. Replace the injector if its rearseats are marred. When reinstalling injector, be sure topush it in until its retaining O-ring is firmly seated in themixer tube.
