●Do not use the welding torch in places where flying spatter can cause
flammable materials to ignite.
●Do not use the welding torch near places where flammable gases are present.
●Keep base metals away from flammable materials immediately after welding
as they may have become hot.
●Remove any flammable materials on the other side of ceilings, floors and walls
that are being welded as sparks from welding could cause such materials to
ignite.
●The welding cable should be connected as close as possible to the base metal
being welded, and it should be connected securely.
●Do not weld gas cylinders which still contain gas.
●Do not weld sealed tanks or pipes.
●Keep a fire extinguisher close by the place where welding is being carried out
in case a fire starts.
CAUTION Wear protective equipment at all times to protect
yourself and others against arc beam, welding flashes,
flying spatter and slag, and noise.
CAUTION
CAUTION Be sure to observe the following to avoid fires,
explosions and rupturing.
CAUTION Use protective equipment at all times to protect
yourself and others against any fumes and gases that
may be generated from welding.
Be sure to observe the following to avoid burns
from the nozzle and tip or injury from fine wire
ends.
●Always wear protective goggles or welding masks which have sufficient
shielding properties when doing welding or when observing welding being
done.
●Wear protective glasses to protect the eyes from spatter and slag.
●Hang a curtain around the area where welding is being carried out to prevent
welding flashes from affecting passers-by.
●Wear protective clothing such as leather gloves, longsleeves, leg
covers and a leather apron for protection while welding.
●Wear noise proof ear protectors if the noise level is too high.
●Inspections and maintenance should be carried out at periodic intervals, and
the equipment must not be used until any damaged parts found have been
repaired or replaced.
●Do not use cables that are damaged or that have exposed conductors, or that
are rated lower than the specified level.
●Make sure that the cable is connected securely and that it is insulated.
●Welding cable should be connected as close as possible to the base metal
being welded and it should be connected securely.
●Do not wear gloves which are torn or wet.
●Use a safety strap if welding in raised places.
●Turn OFF all power switches and the input power supply when not using.
*Welding flashes contain harmful ultraviolet and infrared lights which can cause
inflammation or burn to eyes.
*Flying spatter and slag can hurt the eyes and cause serious burns.
*The noise generated by welding can cause problems with hearing.
*Fumes and gases are generated when welding is carried out. Inhaling fumes
and gases can be dangerous to your health.
*Welding in confined spaces can reduce the oxygen content in the air, which
can result in suffocation.
●To provent gas poisoning and suffocation, always use a proper ventilation
equipment to vent gases locally or entirely as stipulated by labor safety
regulations and air contamination prevention regulations, or use an adequate
breathing apparatus.
●When welding in a confined space, make sure that the air is circulating freely,
wear some kind of breathing apparatus, and work only under the supervision
of a properly trained supervisor.
●Toxic gases may be generated if welding is carried out near where degreasing,
cleaning or demisting operations are also being carried out. Avoid welding near
places where such operations are being carried out.
●Welding metal which has been plated with zinc will cause toxic fumes. Remove
the plating before welding, or wear adequate absorption equipment for
protection.
*The nozzle or contact tip becomes very hot after use, and it can cause serious
burns if touched.
●Do not touch the nozzle or tip immediately after welding has been completed.
●Do not bring the tip of the welding torch close to your face during wire inching.
*Fires can be caused by spatter and base metals which are hot after welding.
*Fire can occur as a result of heat generated by the flow of current if the cable
has not been correctly connected or there is an incomplete contact in the
current path at the base metal being used.
*Explosions can occur if an arc is generated near containers that contain
flammable substances such as gasoline.
*Ruptures can occur if welding sealed objects such as tanks and pipes.
In the above definitions, ''severe injury'' refers to cases of blindness, physical
wounds, burns (high- and medium-temperature), electric shocks, fractures or
poisoning which may leave scars or lasting ill-effects and for which medical
treatment or prolonged hospitalization may be necessary. ''Injury refers to cases
of physical wounds, burns and electric shocks for which prolonged medical
treatment and hospitalization are not necessary, and ''physical damage'' refers
to extensive damage that may result in damaged property or broken equipment.
●Never Torch charged parts such as welding wire, or contact tip while welding
torch is turned ON and operating.
●Grounding of welding power supply case and base metal and tools which are
connected electrically to the base metal, must be carried out by a qualified
electrician in accordance with the proper electrical engineering regulations.
●Turn OFF all input power supplies by turning OFF the switches in the
distribution box before carrying out any inspections or maintenance.
Be sure to read these instructions before using the welding
