1.2 Arc Welding Damage
The following signals and word explanations explain damage or injury that may occur when
welding. Please remind yourself and others to be aware.
Only persons who are authorised can install, debug, operate, maintain and repair the
equipment.
During the operation, only required persons should be present.
After shutting off the machine power, please maintain and examine the equipment according
to Part 5 due to DC voltage existing in the electrolytic capacitors.
ELECTRIC SHOCK CAN KILL.
Never touch electrical parts.
Wear dry, hole-free gloves and clothes to insulate yourself.
Insulate yourself from work and ground using dry insulation. Make certain the insulation is
large enough to cover your full area of physical contact with work and ground.
Take care when using the equipment in restricted spaces, and wet circumstances.
Never close the machine power before installation and adjustment.
Ensure you install the equipment correctly and ground the work or metal to be welded to a
good electrical (earth) ground according to the operation manual.
The electrode and work (or ground) circuits are electrically “hot” when the welder is on. Do not
touch these “hot” parts with your bare skin or wet clothing. Wear dry, hole-free gloves to
insulate hands.
In semiautomatic or automatic wire welding, the electrode, electrode reel, welding head,
nozzle or semiautomatic welding gun are also electrically “hot”.
