All equipment connected to electric power supplies can be dan-
gerous if the manufacturers instructions are not read and obser-
ved. Read, understand and observe these safety instructions
to reduce the risk of death or injury from electric shock. Ensure that
even bystanders are aware of, and understand, the dangers that
exist in the welding area.
Read this manual carefully before using your Welder.
You can then do a better and safer job.
By reading this manual you will learn more about the
possibilities, limitations and potential dangers of welding.

ge ! Read, understand and observe all safety warnings
to reduce the risk of death or injury from fire or explo-
sion. Pay particular attention to the fact that even bystanders should

ten metal drops, hot slag and hot metal parts that can cause fires, can
burn skin and damage eyes.
Fumes, toxic gases and vapours can be harmful ! Read,
understand and observe all safety warnings to avoid harm
from toxic welding gases. Pay particular attention to the fact that even
bystanders should be aware of, and understand, the dangers.
HIGH VOLTAGE
The unit carries potentially lethal voltage.
The high voltage areas of the equipment have been segregated
and can be reached only by using tools that are not provided with the
Welder.
All maintenance or repair operations requiring access to such areas may
only be performed by constructor-trained technicians.
FOREIGN OBJECTS
Never block the air vents with foreign objects and avoid
any contact with liquids. Clean using just a dry cloth. The-
se safety precautions apply even when the unit is switched off.
CABLE GAUGES
Check that all cables are appropriately gauged for
the input power required by your specific Welder.
This precaution applies also to extension cables, if used. All extension
cables must be straight. Coiled cables can overheat, becoming dange-
rous. Twisted or coiled cables can also cause Welder malfunction.
WEIGHT LOADS
The upper part of the Welder was not designed to with-
stand heavy loads. Never stand on the unit.
Carelessness while using or maintaining the compres-
sed gas cylinders or regulators can injure or kill the
operator and/or bystanders ! Read, understand and observe all safety
warnings to avoid the dangers of compressed gas. Pay particular
attention to the fact that even bystanders should be aware of, and
understand, the dangers.
Arc rays can damage your eyes and burn your skin !
