4. Welder operation
4-1 Warning on matters to be observed prior to operation
DANGER
: Make sure to observe the following instructions for avoiding serious accidents
resulting in injury or death.
(1) Observe laws and regulations and your in-house standards for working power sources on the
input side, setup of place of installation, handling of high-pressure gases, storage and piping,
storage of products after welding, disposal of waste and others.
(2) Take measures to prevent people from entering improperly the section around the welder and the
welding work area.
(3) If you use a pacemaker for your heart, do not enter the section around the welder and the welding
work area until your doctor permits it. A welder produces a magnetic field around the welder
while electric power is fed to it, and exerts adverse effect over the operation of your pacemaker.
(4) To secure safety, it is necessary that qualified persons or those who fully understand the welder
execute installation, maintenance and inspection as well as repair to this welder.
DANGER
: Make sure to observe the following instructions for avoiding electric shock.
▪ Fatal electrical stunning and burn may arise, if you touch any live part.
(1) Do not touch any live part.
(2) Do not use a cable of insufficient capacity, a damaged cable or a cable with exposed conductors.
(3) Be sure to tighten and insulate each cable joint.
(4) Do not use the welder in the state where the case or cover is removed from it.
(5) Do not use broken or wet gloves. Always use dry insulating gloves.
(6) Use a life rope in case of working in an overhead location.
(7) Conduct periodic maintenance and inspection. If any damaged portion was found, repair it
before use.
(8) Turn off the power for all the equipment when the welder is not used.
DANGER
: Make sure to observe the following instructions for avoiding fire, explosion
and burst.
▪
Spatter and hot base metal immediately after welding may trigger fire.
▪ If there is any point of incomplete contact in the cable or in the current path on the
base metal side such as steel, fire may break out due to heat generation caused by
current conduction.
▪ A container for combustible substance such as gasoline may explode, if arcing
occurs to it.
▪ An enclosed tank or pipe may burst when it is welded.
(1) Remove combustible materials from the surrounding area, so that scattering spatter will not hit
combustible materials. If they cannot be removed, cover them up with incombustible covers.
(2) Do not perform welding in the vicinity of combustible gases.
(3) Do not bring hot base metal immediately after welding close to combustible materials.
