Safety Quick-Guide

Thank you for using Miller or Hobart arc welding and cut-

ting equipment.
We ask you to work like a pro  and pros weld and cut safely. Please

read and comply with the sample safety procedures outlined in this
guide and the equipment Owner’s Manual.

Always read and follow the Owner’s Manual, the safety labels on the
product, and all applicable safety standards, especially ANSI Z49.1,
Safety in Welding, Cutting, and Allied Processes (we recommend you
get a copy and keep it handy). A list of the safety standards and where
to get them is located in Section 7 of this guide.

Thank you for working safely.

1. General Safe Practices

Become trained and read the

instructions before working on the
machine or welding or cutting

.

Read Material Safety Data Sheet

s

(MSDSs) for metals, consum

-

ables, and coatings.

+

ANSI Z49.1
OSHA 29CFR 1910
MSDSs
Owner’s Manual

Wear approved safety glasses with side shields under you

r

welding helmet or face shield and at all times in the work area.

Read the equipment Owner’s Manual for more complete safet

y

information.
Wear a safety harness if working above floor level.
Keep children away from all equipment and processes.
Do not install or place machine on or over combustible surfaces

.

Have only qualified persons install, use, or service all equipment

.

2. Arc Welding Haz ards

Electric shock from welding electrode or wiring
can kill.

Wear dry insulating gloves. Do not touch electrode with bare hand.
Do not wear wet or damaged gloves.

Do not touch live electrical parts.
Do not use AC weld output in damp, wet, or confined spaces.

Protect yourself from electric shock by insulating yourself from
work and ground. Use non-flammable, dry insulating material if
possible, or use dry rubber mats, dry wood or plywood, or other dry
insulating material big enough to cover your full area of contact
with the work or ground, and watch for fire.

Disconnect input plug or power before working on machine.
Do not make input connections if color blind.
Frequently inspect input power cord for damage or bare wiring —

repair or replace cord immediately if damaged. Be sure input
ground wire is properly connected to a ground terminal in
disconnect box or receptacle.

Properly install and ground all equipment according to its Owner’s
Manual and national, state, and local codes.

Safety Quick-Guide

Use a ventilating fan to remove fumes from the breathing zone and
welding area.

If adequacy of ventilation or exhaust is uncertain, have your
exposure measured and compared to the Threshold Limit Values
(TLV) in the Material Safety Data Sheet (MSDS).

Keep your head out of the fumes. Do not breathe the fumes. Use
enough ventilation, exhaust at the arc, or both, to keep fumes and
gases from your breathing zone and the general area.

Read Material Safety Data Sheets (MSDSs) for metals, consum­ables, and coatings.

Use enough forced ventilation or local exhaust (forced suction) at
the arc to remove the fumes from your breathing area.

Breathing welding fumes can be hazardous to
your health.

Do not weld on drums, tanks, or any closed containers unless a
qualified person has tested it and declared it or prepared it to be
safe (see AWS F4.1 listed in Section 7).

Do not weld near flammable material. Move flammables at least 35
feet (1 1 meters) away or protect them with flame-proof covers (see
NFPA 51B listed in Section 7).

Welding sparks can cause fires. Have a fire extinguisher nearby,
and have a trained fire watch ready to use it.

Welding can cause fire or explosion.

Safety Quick-Guide

Wear complete body protection. Wear oil-free protective clothing
such as leather gloves, heavy shirt, cuffless pants, and high boots.

Wear welders cap and safety glasses with side shields. Use ear
protection when welding out of position or in confined spaces.
Button shirt collar.

Use welding helmet with correct shade of filter (see Section 8 to
choose the correct shade).

Arc rays can burn eyes and skin.

3. Engine Hazards

Engine fuel plus flames or sparks can cause fire or explosion.
Do not weld near engine fuel.
Do not spill fuel. If fuel is spilled, clean it up and do not start engine

until fumes are gone.

+ =

Do not smoke while fueling or if near fuel or fumes.

Stop engine before fueling.

Do not fuel a hot engine. Stop engine and let it cool off before
checking or adding fuel.

Fuel can cause fire or explosion.
