FIRE PREVENTION
WARNING: Failure to protect combustible materials against
welding sparks, hot slag and hot spatters can cause fire and
even explosion. Fire and explosion can cause death, injury
and property damage. To reduce the risks, please read,
understand and follow the safety instructions.
□Check the area before welding. Ensure the work area is
checked and cleared of combustible and flammable
materials. A minimum distance of 35 feet (10 meters) is
required between work area and combustibles because 35
feet is an average distance welding sparks and slags can fly.
If the minimum 35 feet distance requirement cannot be met,
protect consumable/flammable materials with fire resistant
covers or shields.
□Do not weld or cut on or near materials with combustible
coating or combustible internal substance, such as materials
in walls or ceilings, without any approved methods to
eliminate the hazard.
□Do not weld or cut in areas (such as gas station) where the
air may contain flammable substances such as combustible
dust, gas, or liquid vapors.
□Do not wear gloves, hair preparations, shoes and other
clothing that contains oil, grease, or other flammable
substances. Wear fire-resistant protective clothing to protect
upper and lower body against fire and heat. Protective
clothing includes but is not limited to leather gloves, heavy
long sleeve and cuffless shirts, heavy and cuffless pants,
high-topped shoes and helmet.
□Do not dispose of hot slag in containers holding combustible
materials. Keep a fire extinguisher nearby and know how to
use it.
□Follow requirements in OSHA and NFPA for hot work and
have an extinguisher nearby.
□When finished welding, do not leave without a check for
evidence of potential fire. Overlooked smoke or flame have
risks to cause fire hazard. Check and make sure the welding
areas are free of sparks, slags, and flames before leaving
the welding area.

Información de seguridad
SEGURIDAD EN EL ÁREA DE TRABAJO
ADVERTENCIA:
□Asegúrese de que el área de trabajo esté limpia y bien
iluminada.
□Mantenga la soldadora sobre una superficie estable y limpia
mientras hace uso de ella.
□Mantener alejados a visitantes, transeúntes y los niños
mientras se opera la soldadora. Las distracciones pueden
hacerle perder el control.
□No opere la máquina en atmósferas explosivas, como en
presencia de líquidos, gases o polvos inflamables. Las
chispas que saltan durante la soldadura pueden encender el
polvo o los humos.
□No debe abandonar el lugar donde está la máquina
encendida y sin vigilancia. Apague siempre la máquina
antes de realizar el mantenimiento de las piezas, la
sustitución de los componentes o cuando la máquina no
esté en uso.
SEGURIDAD PERSONAL
ADVERTENCIA: Los procesos de soldadura generan
arcos de alta temperatura, chispas al soldar, escoria y
salpicaduras calientes. La soldadura por arco genera una
luz ultravioleta e infrarroja de gran intensidad. Si no se usa
el equipo de protección durante la soldadura, cabe el riesgo
de dañarse gravemente los ojos y quemarse la piel. Para
reducir los riesgos, el operador debe seguir, comprender y
leer las instrucciones de seguridad. Las personas que se
encuentren en la zona también deben seguir las
instrucciones de seguridad bajo la dirección del operador.
ADVERTENCIA:
□No se debe operar sin la protección adecuada. Las chispas
que saltan pueden causar quemaduras. Lleve siempre ropa
de protección y careta. La luz intensa del arco eléctrico
también puede quemar la piel. Asegúrese de llevar zapatos
cerrados, guantes y ropa con material grueso, mangas
largas y cuello.
□No mire un arco eléctrico sin una protección ocular
adecuada. Un arco eléctrico es extremadamente brillante e
intenso y puede quemar la retina del ojo y causar daños
permanentes cuando se lleva una protección ocular
inadecuada o no se lleva.
□No trabaje en lugares cerrados sin una ventilación adecuada.
De lo contrario, use un respirador con suministro de aire.
Laoperación dela soldadora sin
preparación y precaución puede causar la muerte, lesiones
personales oalos transeúntes. Para reducir los riesgos, el
operador debe seguir, comprender yleer lasinstrucciones
de seguridad. Las personasque se encuentren en la zona
también deben seguir lasinstrucciones de seguridad bajo la
dirección del operador.

Información de seguridad (continuación)
□Antes de que se produzca un arco de plasma, debe hacerlo
saber a los transeúntes y debe asegurarse de que se
encuentran a una distancia segura y de que son conscientes
de que exponen su campo de visible a un arco de plasma
intenso.
□Asegurarse de estar en una posición adecuada mientras se
opera la soldadora. No se extienda demasiado. Mantenga el
equilibrio y la posición correcta en todo momento, lo que
permite un mejor control de la soldadora en situaciones
inesperadas.
□Manténgase alerta al operar una soldadora. No utilice la
máquina cuando esté cansado o bajo la influencia de drogas,
alcohol o medicamentos. Evite el arranque involuntario.
□Asegúrese de leer el manual del usuario y de estar bien
preparado antes de soldar.
SEGURIDAD ELÉCTRICA
ADVERTENCIA: El uso inadecuado de las soldadoras
puede provocar una descarga eléctrica. La descarga
eléctrica puede matar. Para reducir los riesgos, el operador
debe seguir, comprender y leer las instrucciones de
seguridad. Las personas que se encuentren en la zona
también deben seguir las instrucciones de seguridad bajo la
dirección del operador.
□No exponga la soldadora a la lluvia ni entre en contacto con
una superficie húmeda. La entrada de agua en la máquina
aumenta el riesgo de descarga eléctrica.
□No toque ni entre en contacto con ninguna parte del circuito
de corriente de la máquina de soldar; como pinzas de tierra,
electrodos, alambres de soldadura, pistolas MIG/TIG, piezas
de trabajo, cualquier pieza metálica o de material conductor
que este en contacto con el portaelectrodos o las piezas de
trabajo.
□No haga contacto con ninguna superficie metálica
conectada a tierra, como tuberías metálicas refrigeradores y
radiadores. Hay un mayor riesgo de descarga eléctrica
cuando su cuerpo está conectado a tierra.
□Asegurarse de que la energía está desconectada antes de
configurar cualquier antorcha TIG/pistola
MIG/portaelectrodos, ajuste y servicios.
□No abuse de los cables. Nunca se debe transportar o
desenchufar la soldadora tirando del cable. Mantenga los
cables alejados del calor, el aceite, los bordes afilados o las
piezas móviles. Los cables dañados o enredados podrían
aumentar el riesgo de descarga eléctrica.
□Inspeccione el soldador antes de utilizarlo. No utilice la
soldadora si observa alguna pieza dañada o agrietada,
incluidos, entre otros, abrazaderas de tierra o cables
dañados o agrietados, etc. Sustituirlas antes de utilizar la
soldadora.
□Utilice un alargador (específico para uso en exteriores)
cuando opere una soldadora al aire libre.
□No apunte los sopletes/pistolas de soldar hacia las personas
cuando los sopletes/pistolas de soldar estén encendidos. No
apunte con la pistola MIG a los ojos en ninguna situación.
□No se debe soldar en zonas húmedas o cuando la soldadora
esté en contacto con agua o superficies mojadas.
□No se debe cortar cuando el cuerpo o la ropa estén mojados.
