MIG/FLUX-CORE WIRE FEED WELDER KIT 058-8195-2
DANGER!
Potential hazard that will result in serious injury or loss of life.
•Keep children or other personnel away from the work area while welding. Do
not allow children to handle the welder.
•Do not use the welder in the presence of flammable liquids or gases. Sparks
that are created during use may ignite gases.
• Do not operate the welder in humid, wet, or poorly ventilated areas.
• Use appropriate shield to prevent other personnel from being affected by
harmful rays.
• Always ensure that a fire extinguisher is available in adequate distance
within the welding environment.
• Do not repair or maintain the welder while the power is on.
•Risk of electric shock: Do not touch electrical live parts or metal
components connected to the welding wire, as doing so may cause fatal
shock and severe burns. Secure the ground lead before welding. Wear dry
protective apparel like coat, shirt, gloves, and insulated footwear.
•Risk for breathing: Never directly inhale the emission of harmful fumes when
welding on coated materials like galvanized, cadmium plated or contacting
zinc, mercury, or barium.
•Risk of fire: Do not weld on containers or pipes that contain flammable,
gaseous, or liquid combustibles. Remove all flammable materials within 35
feet of the welding arc or tightly cover the flammabe materials with fireproof
covers. To prevent any unintended arcs after welding, cut off the excess wire
that extends past the end of the nozzle more than ¼".
•Risk of burns: Do not touch the welded materials with bare hands, as the
welded materials are hot and can cause severe burns.
SAFETY GUIDELINES

•Risk of explosion: Keep high pressure shielding gas cylinder away from
welding or electrical circuits. Do not touch the cylinder with MIG gun and do
not weld on the cylinder. Use proper regulators, gas hoses, and fittings for
the specific application.
• Do not expose the welder to rain.
•Risk of UV and IR arc rays: Do not look at the welding arc without proper eye
protection, as the welding arc produces ultraviolet (UV) and infrared (IR) rays.
Use screens or other barriers to protect other personnel from the rays.
