Safety Instructions for

MIG Welders

1. READ THIS MANUAL.

This manual con-

tains proper operating and safety proce-
dures for this equipment.

2.

WELDING FUMES.

Breathing welding

fumes  can  cause  suffocation  or  poisoning
without  warning.  Keep  your  head  out  of
welding  fumes.  Use  adequate  ventilation
at the arc to safely remove the fumes from
your breathing zone and the general area.
Use ANSI approved respirators for the type
of  welding  operation.  Protect  others  from
these fumes.

3. WELDING IN A CONFINED SPACE CAN

BE HAZARDOUS.

Always open all covers,

sustain forced ventilation, remove toxic and
hazardous  materials,  and  provide  a  power
disconnect  to  the  welder  inside  the  work
space.  Always  work  with  someone  who
can give you help from outside the space.
Welding can displace oxygen. Always check
for safe breathing atmosphere and provide
air-supplied  respirators  if  necessary.  Keep
in mind that all normal welding hazards are
intensified in a confined space.
