The engine exhaust from this product contains chemicals known to the State of California to cause cancer, birth defects, or other reproductive harm.
The Above For Gasoline Engines
FOR ENGINE powered equipment.
1.a. Turn the engine off before troubleshooting and maintenance work unless the maintenance work requires it to be running.
____________________________________________________
1.b. Operate engines in open, well-ventilated areas or vent the engine exhaust fumes outdoors.
____________________________________________________
1.c. 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.
____________________________________________________
1.d. 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.
____________________________________________________
1.e. 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. Always use the greatest care when working near moving parts.
___________________________________________________
1.f. 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.
1.h. To avoid scalding, do not remove the radiator pressure cap when the engine is hot.
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.
___________________________________________________
1.g. 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.
MOBIFLEX 400-MS(/HE) BASE UNIT & LFA 3.1/4.1 MOBILE MANUAL/AUTOMATIC
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.

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 Items 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.
FUMES AND GASES 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 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 within applicable OSHA PEL and ACGIH TLV limits 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.
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 coming from degreasing, cleaning or spraying operations. The heat and rays of the arc can react with solvent vapors form phosgene, a highly toxic gas, and other irritating prod­ucts.

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
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 been “cleaned”. For information, purchase “Recommended Safe Practices for the 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.
Sparks and spatter are thrown from the welding arc. Wear oil
6.f. 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.

PRÉCAUTIONS DE SÛRETÉ
Pour votre propre protection lire et observer toutes les instructions et les précautions de sûreté specifiques qui parraissent dans ce manuel aussi bien que les précautions de sûreté générales suiv­antes:
Sûreté Pour Soudage A LʼArc
1. Protegez-vous contre la secousse électrique:
a. Les circuits à lʼélectrode et à la piéce sont sous tension
quand la machine à souder est en marche. Eviter toujours tout contact entre les parties sous tension et la peau nue ou les vétements mouillés. Porter des gants secs et sans trous pour isoler les mains.
b. Faire trés attention de bien sʼisoler de la masse quand on
soude dans des endroits humides, ou sur un plancher met­allique ou des grilles metalliques, principalement dans les positions assis ou couché pour lesquelles une grande partie du corps peut être en contact avec la masse.
c. Maintenir le porte-électrode, la pince de masse, le câble de
soudage et la machine à souder en bon et sûr état defonc­tionnement.
d.Ne jamais plonger le porte-électrode dans lʼeau pour le
refroidir.
e. Ne jamais toucher simultanément les parties sous tension
des porte-électrodes connectés à deux machines à souder parce que la tension entre les deux pinces peut être le total de la tension à vide des deux machines.
f. Si on utilise la machine à souder comme une source de
courant pour soudage semi-automatique, ces precautions pour le porte-électrode sʼapplicuent aussi au pistolet de soudage.
2. Dans le cas de travail au dessus du niveau du sol, se protéger contre les chutes dans le cas ou on recoit un choc. Ne jamais enrouler le câble-électrode autour de nʼimporte quelle partie du corps.
5. Toujours porter des lunettes de sécurité dans la zone de soudage. Utiliser des lunettes avec écrans lateraux dans les zones où lʼon pique le laitier.
6. Eloigner les matériaux inflammables ou les recouvrir afin de prévenir tout risque dʼincendie dû aux étincelles.
7. Quand on ne soude pas, poser la pince à une endroit isolé de la masse. Un court-circuit accidental peut provoquer un échauffement et un risque dʼincendie.
8. Sʼassurer que la masse est connectée le plus prés possible de la zone de travail quʼil est pratique de le faire. Si on place la masse sur la charpente de la construction ou dʼautres endroits éloignés de la zone de travail, on augmente le risque de voir passer le courant de soudage par les chaines de levage, câbles de grue, ou autres circuits. Cela peut provoquer des risques dʼincendie ou dʼechauffement des chaines et des câbles jusquʼà ce quʼils se rompent.
9. Assurer une ventilation suffisante dans la zone de soudage. Ceci est particuliérement important pour le soudage de tôles galvanisées plombées, ou cadmiées ou tout autre métal qui produit des fumeés toxiques.
10. Ne pas souder en présence de vapeurs de chlore provenant dʼopérations de dégraissage, nettoyage ou pistolage. La chaleur ou les rayons de lʼarc peuvent réagir avec les vapeurs du solvant pour produire du phosgéne (gas fortement toxique) ou autres produits irritants.
11. Pour obtenir de plus amples renseignements sur la sûreté, voir le code “Code for safety in welding and cutting” CSA Standard W 117.2-1974.
PRÉCAUTIONS DE SÛRETÉ POUR
3. Un coup dʼarc peut être plus sévère quʼun coup de soliel, donc:
a. Utiliser un bon masque avec un verre filtrant approprié ainsi
quʼun verre blanc afin de se protéger les yeux du rayon­nement de lʼarc et des projections quand on soude ou quand on regarde lʼarc.
b. Porter des vêtements convenables afin de protéger la peau
de soudeur et des aides contre le rayonnement de lʻarc.
c. Protéger lʼautre personnel travaillant à proximité au
soudage à lʼaide dʼécrans appropriés et non-inflammables.
4. Des gouttes de laitier en fusion sont émises de lʼarc de soudage. Se protéger avec des vêtements de protection libres de lʼhuile, tels que les gants en cuir, chemise épaisse, pan­talons sans revers, et chaussures montantes.
MOBIFLEX 400-MS(/HE) BASE UNIT & LFA 3.1/4.1 MOBILE MANUAL/AUTOMATIC
LES MACHINES À SOUDER À TRANSFORMATEUR ET À REDRESSEUR
1. Relier à la terre le chassis du poste conformement au code de lʼélectricité et aux recommendations du fabricant. Le dispositif de montage ou la piece à souder doit être branché à une bonne mise à la terre.
2. Autant que possible, Iʼinstallation et lʼentretien du poste seront effectués par un électricien qualifié.
3. Avant de faires des travaux à lʼinterieur de poste, la debranch­er à lʼinterrupteur à la boite de fusibles.
4. Garder tous les couvercles et dispositifs de sûreté à leur place.

LFA 3.1/4.1 MOBILE MANUAL/AUTOMATIC
The LFA 3.1/4.1 Mobile Manual and Mobile Automatic Extraction Arms are flexible fume extraction arms with a 360° rotatable hood. Incorporated into the arms hood is a throttle valve that can be fully opened, partially opened or completely closed to control airflow at hood opening. The hood features an airflow focus vane, which directs the air into the hood.
The armsʼ balance system increases its durability and stability. As soon as the arms are raised, they are free to move in any direction. Once the arms are posi­tioned, they are fixed into place. This makes reposi­tioning the arms simple, easy and effortless.
The extraction arms are made of solid, lightweight, 8 inch (203 mm) diameter dent and scratch resistant tubes. They are provided with a spring balance system for ultra-light, user friendly positioning of the arms.

LFA 3.1/4.1 MOBILE MANUAL/AUTOMATIC
The LFA 3.1/4.1 Mobile Manual and Mobile Automatic Extraction Arms are flexible fume extraction arms with a 360° rotatable hood. Incorporated into the arms hood is a throttle valve that can be fully opened, partially opened or completely closed to control airflow at hood opening. The hood features an airflow focus vane, which directs the air into the hood.
The armsʼ balance system increases its durability and stability. As soon as the arms are raised, they are free to move in any direction. Once the arms are posi­tioned, they are fixed into place. This makes reposi­tioning the arms simple, easy and effortless.
The extraction arms are made of solid, lightweight, 8 inch (203 mm) diameter dent and scratch resistant tubes. They are provided with a spring balance system for ultra-light, user friendly positioning of the arms.
FIGURE B.1
OPERATION
The air which contains welding fume is captured, extracted and filtered, before being recirculated back into the work environment. First, the welding fume is extracted through an adjustable fume extraction arm by the internal extraction fan.
Second, as the welding fume enters the Base Unit, it passes through the prefilter. The prefilter separates larger particles, debris and most sparks prior to the welding fume entering the LongLife filter. Third, the air passes from the outside through the LongLife filter car­tridge. Fourth, after passing through the LongLife filter, the filtered air exits the Mobiflex 400-MS(/HE) Base Unit via the outlet grid at top of filter housing.
During use, an electronic pressure differential system measures the static air pressure as it enters and exits the filter cartridge. If the air pressure entering the filter unit is greater than the air pressure exiting the filter unit, the electronic circuit signals the internal cleaning system to clean the filter cartridge. Compressed air from the internal tank releases through multiple airjets to clean one section of the filter cartridge at each air burst. A complete cleaning cycle can be activated by depressing a manual switch on the front of the control panel. The particulate is blown off the filter cartridge into a dust tray.
The K2633-2 and K2633-4 LFA 3.1/4.1 Mobile Automatic arms contains an integrated Lamp & Arc Sensor Kit in the hood. The 35W/24V halogen lamp provides additional light to the workpiece. With the use of a delayed arc sensor, the extraction fan will operate automatically. The automatic start/stop utilizes a 20 second auto stop to help conserve energy and reduce noise level.

------------------------------------------------------------------------
AUTOMATIC FILTER CLEANING SYSTEM
CONTROL LIGHT: CLEANING
During normal operation (i.e. with a clean, non-saturat­ed filter cartridge), the Mobiflex 400-MS(/HE) functions automatically. As soon as a minimum airflow has been reached as a result of the clogging, the pressure dif­ference switch activates the RotaPulse compressed air cleaning system which subsequently cleans the filter using controlled jets of compressed air. The particulate then falls into the dust tray.
During the automatic cleaning process the control light (See Figure B.2 item D) is on (“CLEANING”). The cleaning system stops when the airflow is sufficient again.
This procedure is called online cleaning.
When no welding takes place for the automatic clean­ing process, the fan will start running for 30 seconds after every four compressed airjets to check the pres­sure difference. This happens 15 times maximum.
When the airflow hasnʼt reached the required airflow rate after 60 compressed airjets, the control light will change into the “ALARM” mode.
• In this case, proceed with Control light: ALARM pro­cedure.

CONTROL LIGHT: ALARM
When the control light (See Figure B.2 item D) blinks (“ALARM”), proceed as follows.
• Stop welding.
• Press filter cleaning ON/OFF - RESET button (See Figure B.2 item E) to stop the control light from blink­ing.
• Make sure the FAN ON/OFF switch (See Figure B.2 item C) is off.
• Close throttle valve in extraction hood.
• Press filter cleaning ON/OFF - RESET button again (See Figure B.2 item E) to start off-line cleaning.
During the off-line cleaning cycle the entire filter car­tridge is cleaned systematically by compressed airjets. This cycle takes approximately one hour.
ATTENTION
Do not use the machine during the off-line cleaning cycle.
OFF-LINE CLEANING
It is recommended to perform a manual off-line clean­ing routine a minimum of twice a week.
ATTENTION
For more efficient filter cleaning, it is recommended to carry out an off­line cleaning cycle on a regular basis.
------------------------------------------------------------------------
ATTENTION
For off-line cleaning after working hours, make sure compressed air is connected and available.
------------------------------------------------------------------------
ATTENTION
------------------------------------------------------------------------
ATTENTION
If desired, the off-line cleaning cycle can be interrupted by pressing the filter cleaning ON/OFF - RESET but­ton (See Figure B.2 item E) .
------------------------------------------------------------------------
After the cleaning cycle is finished, system operation can be continued.
When you continue welding and the control light starts blinking again immediately or shortly after the cleaning cycle is finished, the LongLife filter cartridge is saturat­ed and should be replaced.
See Filter Replacement.
WARNING
Saturation or clogging of the filter cartridge results in a decrease of the extraction capacity which could result in a reduced extraction of welding fumes.
