Safety precautions 

 

welding power source 

Observe  the  following  instructions  to 
prevent the hazard. 

(1)Never  use  the  welding  power  source  for  other  than 
welding purpose. (e.g. Never attempt to use the welding 
power source for pipe thawing.) 
(2)It  is  very  important  to  comply  with  all  instructions, 
safety  warnings,  cautions  and  notes  mentioned.  Failure 
to do so can result in serious injury or even death. 
(3)Work  of  driving  source  at  the  input  side,  selecting 
work site,  handling,  storage and piping of high pressure 
gas,  storage  of  welded  products  and  also  disposal  of 
waste  should  be  performed  according  to  the  operating 
instructions  and  national,  state  and  local  codes  and 
regulations. 
(4)Prevent  any  unauthorized  personnel  to  enter  in  and 
around the welding work area. 
(5)Pacemaker wearers should consult their doctor before 
going  near  arc  welding.  Magnetic  fields  can  affect 
pacemakers. 
(6)Only  educated  and/or  skilled  persons  who  well 
understand  this  welding  power  source  should  install, 
operate, maintain and repair the unit. 
(7)Only  educated  and/or  skilled  persons  who  well 
understand the operating instructions of the  unit and are 
capable of safe handling should perform operation of the 
unit. 
Against electric shock 

 

Observe  the  following  instructions  to 
prevent the hazard. 

(1)Do not touch live parts. 
(2)Grounding of the case of the welding power and base 
metal  or  a  jig  electrically  connected  to  the  base  metal 
must be performed by educated and/or skilled persons. 
(3)Before  installation  or  maintenance  work,  turn  off 
power at the power box, wait it for at least five minutes 
to discharge capacitors. Significant voltage may exist on 
capacitors after turning off power at the power box so it 
is  imperative  to  check  to  make  sure  that  no  charged 
voltage present at capacitors before touching any parts.   
(4)Do not use undersized,  worn, damaged or bare wired 
cables. 
(5)Connect cables firm and insulate connection parts. 
(6)Keep all cases, panels and covers securely in place. 
(7)Do not handle the welding power source with torn or 
wet gloves. 
(8)Wear  safety  harness  in  case  of  working  above  floor 
level. 
(9)Turn off all equipment when not in use. 
 

(10)Perform  periodic  checks  without  fail  and  repair  or 
replace  any  damaged  parts  before  using  the  power 
source. 
Ventilation and protective equipment 

 

Oxygen deficit, fume and gas generated 
during welding can be hazardous. 

(1)When  conducting  welding  in  the  bottom  of  the  tank, 
boiler or hold as well as legally-defined sites, use a local 
exhauster  specified  by  the  applicable  laws  and 
regulations  (occupational  safety  and  health  regulation, 
rules  on  preventing  suffocation  or  etc.)  or  wear 
protective breathing gear. 
(2)To  prevent  dust  injury  or  poisoning  by  the  fume 
generated during welding, use a local exhauster specified 
by  the  applicable  law  (occupational  safety  and  health 
regulation, rules on preventing injury by inhaled dust or 
etc.), or wear protective breathing gear. 
(3)When  conducting  welding  in  a  confined  area,  make 
sure  to  provide  sufficient  ventilation  or  wear  protective 
breathing gear and have a trained supervisor observe the 
workers. 
(4)Do  not  conduct  welding  at  a  site  where  degreasing, 
cleaning  or  spraying  is  performed.  Conducting  welding 
near  the  area  where  any  of  these  types  of  work  is 
performed can generate toxic gases. 
(5)When  welding a coated steel plate, provide sufficient 
ventilation  or  wear  protective  breathing  gear.  (Welding 
of coated steel plates generates toxic fume and gas.)   
Against fire, explosion or blowout 

 

Observe  the  following  cautions  to 
prevent fires explosion or blowout. 

(1)Remove  any  combustible  materials  at  and  near  the 
work  site  to  prevent  them  from  being  exposed  to  the 
spatter.  If  they  cannot  be  relocated,  cover  them  with  a 
fireproofing cover.   
(2)Do not conduct welding near combustible gases. 
(3)Do not bring the hot base metal near combustible 
materials immediately after welding. 
(4)When  welding  a  ceiling,  floor  or  wall,  remove  all 
flammables including ones located in hidden places. 
(5)Properly connect cables and insulate connected 
parts. Improper cable connections or touching of 
cables to any electric current passage of the base 
metal, such as steel beam, can cause fire.   
(6)Connect  the  base  metal  cable  at  a  section  closest  to 
the welding part. 
(7)Do  not  weld  a  sealed  tank  or  a  pipe  that  contains  a 
gas. 
(8)Keep  a  fire  extinguisher  near  the  welding  site  for  an 
emergency.
