After making welding seam move the
electrode back. This is necessary for
filling the welding crater.
DanGerous factors when
performinG welDinG
operations
Fire prevention
• All inflammable materials should be
removed from the welding area.
• Do not strike the arc on a gas tank or
near it.
• Never attempt to weld fuel tanks or
tanks filled with gas unless all measures
are taken to guarantee that they contain
no fumes.
• Before welding fuel tanks they must be
thoroughly cleaned with steam.
Welding fumes
When welding, toxic fumes are emitted.
Always work in well ventilated areas.
Electric arc light
Always use protecting mask or welding
helmet, equipped with corresponding
glass filter. Never use damaged safety
equipment.
High temperature
Use protective gloves. They provide
hands protection from ultra-violet light
and heat, emitted by electric arc. It is
recommended to wear special clothing.
aDDitional protective
cloths
When welding with heavy current use
protecting apron, which will protect you
from spatter.
When performing overhead welding use
adequate head wear, which will protect
your head and neck.
It is recommended to wear closed safety
boots with steel toe caps.

maintenance
WARNING! Before disassembling
any panel of the machine for performing
any operations inside disconnect the plug
from the receptacle.
Regularly, depending on usage in dusty
environment, perform maintenance of
the machine internals. Remove dust from
internal components of the machine with
low pressure air flow.
After maintenance reinstall panels and
tighten screws.
Never perform welding when the
machine is open!
troubleshootinG
Before contacting service center
for technical assistance perform the
following checks:
• Ensure the welding current regulated by
potentiometer corresponds the diameter
and type of the used electrode.
• Power indicator (On) shall not lit when
there is power failure (check cables,
outputs, fumes etc.).
• Yellow indicator shows overheating,
short circuit, too low or too high voltage.
• Check voltage of the power line.
