Electric shock risk related to welding machine divides into two categories:
Primary voltage shock (e.g. 230-460 V)
Secondary voltage shock (e.g. 20-100 V)
ELECTRIC SHOCK can kill.
All equipment, cables, hoses and gas cylinders should be kept away from busy places
such as doors, aisles and stairs. Care should be taken for the tidiness of the environment
and when welding is completed working environment should be cleaned. By this way,
both work safety and working efficiency will increase. Besides, other workers near the
welding area may step into weld pool by mistake, therefore safety guards should be
placed around the welding area during welding.
Electric shock danger is the most serious risk that operator may encounter frequently.
Contacting electrically hot parts may cause injuries, death or falling down due to electric
shock and sudden reflex. While machine is operating, do not touch to the electrode,
ground connection or live work piece connected to the machine. Insulate yourself against
electrode, grounding connection or work piece. Immediately after plugging out the power
cable, do not touch metal ends of power cable, there may be electric shock danger.
Primary electric shock is very dangerous since it is much higher than welding voltage.
When the power to the machine is open, you can encounter with primary electric
shock while your body is in contact with ground or touching a live point within the
machine. Please note that turning off the ON/OFF switch located on the machine do
not cut off the electric. To cut off the electric to the machine it is necessary to
disconnect the supply cable from connection point or to shut down the fuse of
incoming electric.
Never remove side covers of the machine and in case of failure have an authorized
technician to inspect and repair it.
Be sure to ground the machine and work piece.
While installing the machine and making ground connection, follow general electric
rules, all local laws and regulations and instructions of the manufacturer company.
Do not use uninsulated cables and pliers, replace with the new ones. Never dip the
electrode in water for cooling.
