vapors. Do not use this product in a 
damp or wet location. 

4. 

Avoid unintentional starting. 

Make 

sure you are prepared to begin work 
before turning on the tool. 

5. 

Never leave the tool unattended 
when it is plugged into an electrical 
outlet. 

Turn off the tool, and unplug it 

from its electrical outlet before leaving. 

6.  Always unplug the tool from its 

electrical outlet before performing 
and inspection, maintenance, or 
cleaning procedures. 

7. 

Prevent eye injury and burns.

 

Wearing and using the approved 
personal safety clothing and safety 
devices reduce the risk for injury. 
a.  Wear the approved safety impact 

eye goggles with a welding helmet 
featuring at least a number 10 
shade lens rating. 

b.  Leather leggings, fire resistant 

shoes or boots should be worn 
when using this product. Do not 
wear pants with cuffs, shirts with 
open pockets, or any clothing that 
can catch and  hold molten metal 
or sparks. 

c.  Keep clothing free of grease, oil, 

solvents, or any flammable 
substances. Wear dry, insulating 
gloves and protective clothing. 

d.  Wear an approved head covering 

to protect the head and neck. Use 
aprons, cape, sleeves, shoulder 
covers, and bibs designed and 
approved for welding and cutting 
procedures. 

e.  When welding/cutting overhead or 

in confined spaces, wear flame 
resistant ear plugs or ear muffs to 
keep sparks out of ears. 

8. 

Prevent accidental fires.

  Remove 

any combustible material from the 

work area. 
a.  When possible, move the work to 

a location well away from 
combustible; protect the 
combustibles with a cover made of 
fire resistant material. 

b.  Remove or make safe all 

combustible materials for a radius 
of 35 feet (10 meters) around the 
work area. Use a fire resistant 
material to cover or block all open 
doorways, windows, cracks, and 
other openings. 

c.  Enclose the work area with 

portable fire resistant screens. 
Protect combustible walls, ceilings, 
floors, etc., from sparks and heat 
with fire resistant covers. 

d.  If working on a metal wall, ceiling, 

etc., prevent ignition of 
combustibles on the other side by 
mobbing the combustibles to a 
safe location. If relocation of 
combustibles is not possible, 
designate someone to serve as a 
fire watch, equipped with a fire 
extinguisher, during the welding 
process and for at least one half 
hour after the welding is 
completed. 

e.  Do not weld or cut on materials 

having a combustible coating or 
combustible internal structure, as 
in walls or ceilings, without an 
approved method for eliminating 
the hazard. 

f.  Do not dispose of hot slag in 

containers holding combustible 
materials. Keep a fire extinguisher 
nearby and know how to use it. 

g.  After welding or cutting, make a 

thorough examination for evidence 
of fire. Be aware that easily visible 
smoke or flame may not be
