Safety Precautions

1

These general safety norms cover both arc welding 
machines and plasma cutting machines unless 
otherwise noted.

The  equipment  must  only  be  used  for  the  purpose  it  was 
designed  for.  Using  it  in  any  other  way  could  result  in 
damage or injury and in breach of the safety rules.

Only suitably trained and competent persons should use the 
equipment.  Operators  should    respect  the  safety  of  other 
persons.

Prevention against electric shock

The equipment should be installed by a qualified person and 
in  accordance  with  current  standards  in  operation.It  is  the 
users  responsibility  to  ensure  that  the  equipment  is 
connected  to  a  suitable  power  supply.  Consult  with  your 
utility supplier if required

If  earth  grounding  of  the  work  piece  is  required,  ground  it 
directly with a separate cable. 

Do not use the equipment with the covers removed.

Do  not  touch  live  electrical  parts  or  parts  which  are 
electrically charged. 

Turn o

 all equipment when not in use. 

Cables  (both  primary  supply  and  welding)  should  be 
regularly  checked  for  damage  and  overheating.  Do  not  use 
worn, damaged, under sized, or poorly jointed cables.

Ensure that you wear the correct protective clothing, gloves, 
head and eye protection. 

Insulate yourself from work and ground using dry insulating 
mats or covers big enough to prevent any physical contact 
with the work ground. 

Never touch the electrode if you are in contact with the work 
ground, or another electrode from a di

erent machine. 

Do not wrap cables over your body. 

Ensure that you take additional safety precautions when you 
are  welding  in  electrically  hazardous  conditions  such  as 
damp  environments,  wearing  wet  clothing,  and  metal 
structures.  Try  to  avoid  welding  in  cramped  or  restricted 
positions. 

Ensure  that  the  equipment  is  well  maintained.  Repair  or 
replace damaged or   defective parts immediately. Carry out 
any  regular  maintenance  in  accordance  with  the 
manufacturers instructions.

Safety against fumes and welding gases

Locate the equipment in a well-ventilated position.

Keep your head out of the fumes. Do not breathe the fumes. 

Ensure the welding zone is in a well-ventilated area. If this is 
not  possible  provision  should  be  made  for  suitable  fume 
extraction. 

If ventilation is poor, wear an approved respirator. 

Read  and  understand  the  Material  Safety  Data  Sheets 
(MSDS’s)  and  the  manufacturer’s  instructions  for  metals, 
consumable, coatings, cleaners, and de-greasers. 

Do not weld in locations near any de-greasing, cleaning, or 
spraying operations.  Be aware that heat and rays of the arc 
can  react  with  vapours  to  form  highly  toxic  and  irritating 
gases.
