WARNING
Strictly observe the following to prevent electric shock.
■
Do not touch the charged section; otherwise fatal electric shock or burns can
result. When the power on the input side is turned on, the Input circuit and the
inside of the welding machine are charged. Even if the input power is turned off,
the capacitor may have been charged. When the welding power is output, the
electrode and base metal, as well as the metal portion in contact with these, are
charged.
■
Never touch charged sections.
■
The welding power supply case and base metal, as well as jigs electrically
connected to them, shall be grounded in conformity with the law (Technical
Standard for Electric Equipment) by a qualified electric engineer.
■
Turn off all power supplies on the input side by means of switches in the switch
boxes before installation, maintenance, and inspection. The capacitor will not
discharge completely right after the input power is turned off. Check that no
vohage is remaining before maintenance or inspection.
■
Periodically conduct maintenance and inspection. Repair damaged parts before
resuming operation.
■
Do not use cables with Insufflcient capacity or damaged cables whose conductors
are exposed.
■
firmly tighten and insulate cable connections.
■
Firmly connect the welding cable on the base metal side at a location as close as
possible to the base metal.
■
Do not use the machine with the welding machine case or coser removed.
■
Be sure to cover the input and output terminals before use.
■
Do not use broken or wet gauntlets.
■
Never fail to use a life-line when working in high places.
■
Turn oft power switches of all devices and input-side power supply when the
machine is not used.
■
Do not wear wet clothes.
■
Do not stand on or touch the wet floor.
■
Do not use the machine outdoors when it is raining.
■
Do not leave the machine outdoors after use.
■
Be sure to install a fuse or breaker on the input power supply side.
■
Check the supply voltage of the machine before use.
The tolerance for the input supply voltage is plus or minus 10% of the rating. Use
of the machine out of the folerance is prohibited.
■
The metal receptacle (plug) on the tough-rubber sheath cable is threaded.
Tighten it firmly.
■
Be sure to ground the tough-rubber sheath cable of the machine.
■
Turn off the power and stop operation in the following cases, and ask an engineer
with special knowledge of electricity to repair.
*Broken or worn-out cables
*Damage due to water leakage or other liquid
*Malfunction of the machine inspire of operation in conformity with the instruction
manual.
*Breakdown of the machine.
*Abnormal performance of the machine which requires tune-up.
■
Ask an engineer with expertise to maintain, inspect, or repair the machire.
■
Please make sure that any foreign material does not attach to the connector of the
machine nor to the plug of the power cable when the plug of the power cable is
connected to the machine. Foreign materials can cause short-circuits or melt the
connector.
