SECTION 1 - SAFETY PRECAUTIONS - READ BEFORE USING

WARNING

-  DANGER!  -  Indicates  a  hazardous  situation  which,  if  not  avoided,  will  result  in  death  or  serious  injury.  The  possible  hazards
are  shown  in  the  adjoining  symbols  or  explained  in  the  text

-  Indicates  a  hazardous  situation  which,  if  not  avoided,  could  result  in  death  or  serious  injury.  The  possible  hazards  are  shown
in  the  adjoining  symbols  or  explained  in  the  text.

-  The  symbols  shown  below  are  used  throughout  this  manual  to  call  attention  to  and  identify  possible  hazards.  When  you
see  the  symbol,  watch  out,  and  follow  the  related  instructions  to  avoid  the  hazard.  The  safety  information  given  below  is
only  a  summary  of  the  more  complete  safety  information  found  in  the  Safety  Standards.

-  Only  qualified  persons  should  install,  operate,  maintain,  and
repair  this  unit.

-  During  operation,  keep  everybody,  especially  children,  away.

ARC  WELDING  can  be  hazardous.

ELECTRIC SHOCK can kill.

Touching  live  electrical  parts  can  cause  fatal  shocks
or  severe  burns.  The  electrode  and  work  circuit  is
electrically  live  whenever  the  output  is  on.  The  input
power  circuit  and  machine  internal  circuits  are  also
live when power  is on. In semiautomatic  or automatic
wire  welding,  the  wire,  wire  reel,  drive  roll  housing,

and  all  metal  parts  touching  the  welding  wire  are  electrically  live.
Incorrectly  installed  or  improperly  grounded  equiment  is  a  hazard.

  1.- Do  not  touch  live  electrical  parts.
  2.- W ear  dry,  hole-free  insulating  gloves  and  body  protection.
  3.- Insulate  yourself  from  work  and  ground  using  dry  insulating
mats  or  covers.

  4.- Disconnect  input  power  or  stop  engine  before  installing  or

servicing  this  equipment.

  5.- Properly  install  and  ground  this  equipment  according  to  this
            Owner's  Manual  and  national,  state,  and  local  codes.
  6.- Turn  off  all  equipment  when  not  in  use.
  7.- Do  not  use  worn,  damaged,  undersized,  or  poorly  spliced  cables.
  8.- Do  not  wrap  cables  around  your  body.
  9.- Ground  the  workpiece  to  a  good  electrical  (earth)  ground.
10.- Do  not  touch  electrode  while  in  contact  with  the  work  (ground)

circuit.

11.- Use  only  well-maintained    equipment.  Repair  or  replace  damaged

parts  at  once.

12.- Wear  a  safety  harness  to  prevent  falling  if  working  above  floor
       level.
13.- Keep  all  panels  and  cover  securely  in  place.

ARC RAYS can burn eyes and skin;
NOISE can damage hearing.

Arc  rays  from  the  welding  process  produce  intense
heat and strong ultraviolet rays  that can burn eyes and
skin. Noise from some processes can damage hearing.

1.- Wear  a  welding  helmet  fitted  with  a  proper  shade

of  filter  (see    ANSIZ49.1  listed  in  Safety  Standards)  to  protect

FUMES AND GASES can be hazardous
to your health.

Welding  produces  fumes  and  gases.  Breathing  these
fumes  and  gases  can  be  hazardous  to  your  health.

1.-  Keep  your  head  out  of  the  fumes.  Do  not  breath  the

  fumes.

2.- If  inside, ventilate the  area and /  or use  forced ventilation at  the arc
to  remove  welding  fumes  and  gases.
3.-  If  ventilation  is  poor,  use  an  approved  air-supplied  respirator.
4.-  Read  the  Material  Safety  Data  Sheets  (MSDSs)  and  the

manufacturer´s  instruction  for  metal,  consumables,  coatings,  and
cleaners.

5.- Work in a confined space only if it is well ventilated, or while wearing

an  air-supplied  respirator.  Shielding  gases  used  for  welding  can
displace air causing injury or death. Be sure the breathing air is safe.

6.-  Do  not  weld  in  locations  near  degreasing,  cleaning,  or  spraying

operations.  The  heat  and  rays  of  the  arc  can  react  with  vapors  to
form

  highly  toxic  and  irritating  gases.

7.- Do not weld on coated metals, such as galvanized, lead, or cadmium

plated  steel,  unless  the  coating  is  removed  from  the  weld  area,  the
area  is  well  ventilated,  and  if  necessary,  while  wearing  an  air-
supplied  respirator.  The  coatings  and  any  metals  containing  these
elements  can  give  off  toxic  fumes  if  welded.

FLYING SPARK AND HOT METAL can
cause injury

Chipping  and  grinding  cause  flying  metal  .  As  welds
cool,  they  can  throw  off  slag.

1.-  Wear  approved  face  shield  or  safety  goggles.  Side  shields

recommended.

2.-  Wear  proper  body  protection  to  protect  skin.

your  face  and  eyes  when  welding  or  watching.
2.- Wear  approved  safety  glasses.  Side  shields  recommended.
3.- Use  protective  screens  or  barriers to  protect  others  from  flash  and

glade;  warn  others  not  to  watch  the  arc.

4.- Wear  protective  clothing  made  from  durable,  flame-  resistant  mate

rial  (wool  and  leather)  and  foot  protection.

5.- Use  approved  ear  plugs  or  ear  muffs  if  noise  level  is  high.
