FAULT
FAULT CAUSE
FAULT RECOVERY
Improper arc starting in the
manual consumable-
electrode arc welding the
state indicator flashes green
The power supply voltage is
close to the minimum
allowable voltage of 165 V
If it is not possible to increase the
cross-section of the conductors of
the power cable, decrease the set
welding current to the value which
is sufficient for arc staring. Select
the welding electrode with
consideration for the welding
current
Random arc extinction
during welding
The arc voltage is too high
for the electrode used
Use another electrode or a welding
unit rated at higher power
The electrode sticks to the
workpiece
The welding current is too
low
Set the proper welding current
Low quality of the weld
(metal scattering)
The polarity of voltage across
the electrode is improper
Change the polarity across the
electrode according to the
instructions of the electrode
manufacturer
The contact of the grounding
clamp with the workpiece is
unreliable
Fasten the grounding clamp to the
workpiece as close to the welding
area as possible
11. SAFETY INSTRUCTIONS
GENERAL INFORMATION
This device may only be used for the purposes for which it was created. This appliance is intended for
use by persons with the requisite qualifications. It is the responsibility of the qualified personnel to
install, service and repair. Please read this manual carefully before installing and using this product.

INSTRUCTION
Before using this product, please read this manual and use the instructions in
this manual. This instruction manual is a basic piece of equipment.
USER RESPONSIBILITIES:
The user agrees to allow only persons who:
have been acquainted with the basic safety rules, have been trained in the use
of welding equipment and have appropriate qualifications. They are familiar
with the chapter "Safety Regulations" and the precautionary guidelines in this
manual.
THREATS
ELECTRIC SHOCK CAN KILL:
Welding devices produce high voltage.
While the machine is connected to the power supply, it is not allowed to
touch the welding handle and the workpiece. All of these elements form a
welding current circuit and may cause electric shock, so avoid touching them
with bare hands and wet or damaged protective clothing. Protective clothing
should not restrain movements. If possible, it should not be made of synthetic
materials.
Electrocution can be fatal !!!
