NEVER ATTEMPT to disassemble, repair or modify the instrument.
Do not touch any parts inside the instrument. Failure to observe this may result
in an electric shock or fire.
For battery replacement, inspection or repair, please contact your dealer or us.
NEVER burn, destroy, cut, crush or chemically decompose the
instrument.
This product incorporates parts containing gallium arsenide (GaAs).
DO NOT place your hands between the electrodes.
When welding, be extremely careful not to get your fingers or hand caught in the
electrodes.
During or immediately after welding, DO NOT touch the welded areas or
electrode.
The welded areas of the workpiece, the electrodes and the welding machine’s
arm are extremely hot. To prevent burns, do not touch these areas.
Ground the instrument.
If the Power Supply is not grounded, you may receive an electric shock in the
event of malfunction or current leak. Be sure to perform grounding work.
ALWAYS use the specified power supply.
Failure to use the power supply specified in the Instruction Manual may result in
a fire or electric shock.
Use the specified cables and connect them securely.
Failure to do so or improper connection may result in a fire or electric shock.
Keep the power and connection cables free of damage.
Do not walk on, twist or tug the cables.
Damaged cable may result in an electric shock, short circuit, or fire.
For repair or replacement, contact your dealer or us.
In the event of an anomaly, STOP the operation.
Continuing the operation with anomalies such as a generation of fumes, a
burning odor, strange noise, or overheating unattended may result in an electric
shock or fire. In the event of the above or other anomaly, immediately contact
your dealer or us.
STAY AWAY from the instrument if you have a pace maker.
If you have a pacemaker, do not approach a welding machine in operation or
the immediate area unless your doctor has given consent.
Welding machines generate a magnetic field which interferes with the operation
of a pacemaker.
ALWAYS wear appropriate work clothing.
Wear protective gear such as gloves, a long-sleeved top and leather apron.
Surface flash and expulsion can cause burns if it contacts the skin.
