The appliance meets the EN 60974-10, class A
requirements. That means it can only be used for
industrial purposes. In unfavourable conditions, the
appliance can cause electromagnetic disturbance.
Unpacking and installation
Unpack the appliance and check it thoroughly for any
damage during transport. Any claim for damages caused
by transport must be lodged by the purchaser with the
transporter.
After unpacking the appliance, put it to a well-ventilated
place, with no dust if possible. In doing so, make sure the
air inlet next to cooling slots is not obstructed.
Warning: It is absolutely important that the air inlet is not
limited around the appliance as this could result in
appliance overloading and subsequent damage of the
internal parts.
At least 200 mm of free and unrestricted space must be
around the appliance.
Do not put any filters or covers before the air intake slots
as the warranty would not apply in such a case.
Note: If the appliance is carried on shoulders, it is
necessary to make sure the air inlet slots are not blocked
Operation
The appliance must be installed by experienced staff. All
connections must meet applicable regulations and be in
full accordance with safety regulations (CENELECHD 427)
Space requirements
Before installing and putting the appliance into operation,
the user must consider the potential electromagnetic
interference in the environment.
The following must be considered:
a)
Other feeder, control, signal and telephone cables
above, below and near the welder:
b)
Radio appliances, television sets and receivers;
c)
Computers and other control devices;
d)
Safety and monitoring devices;
e)
Health of the present persons, e.g. artificial
pacemakers, hearing aids, etc.
f)
Measuring instruments used for calibration
purposes;
g)
Protection of other devices around the welder. They
must be compatible. Moreover, additional protective
and preventive measures may be necessary;
h)
Time of day when welding or other works are to be
performed.
The size of the area considered depends on the building
structure and other activities taking place at the same time;
however, they may be extended to neighbouring buildings.
Reduction of emissions
Main source of power
The welder must be connected in accordance with the
manufacturer details on the main source of power. If there
is any failure, it may be necessary to take additional
preventive measures, e.g. fitting a filter to the main source
of power. Electrical feeder cables of firmly installed
welders must be protected by an insulation tube along the
entire cable. Welding cables must be as short as possible.
Before using this source of power it is necessary to read
carefully the CENELEC standards HD 407 and HD 433.
The insulation cables, electrode holder clamps, plugs and
sockets must be checked and it needs to be made sure the
length and cross section of the welding cables
correspond to the selected current:
Within a cable length of 5 m: minimum cross section of 16
mm²
Cable length of 5-20 m: minimum cross section of 25
mm²
Cable length of 20-30 m: minimum cross section of 35
mm²
Welding with sheathed electrodes
The welder is suitable for all types of electrodes and
cellulose electrodes (AWS 6010). Use the electrode holder
clamps without the protruding retaining screws, meeting
the applicable safety standard.
Make sure the main switch in the back is in the "0"
•
position or more precisely that the main feeder cable
is not plugged.
Connect the welding cables with their polarity being in
•
accordance with the electrode manufacturer details.
The electrical circuit must not be intentionally put into
indirect contact with the protective cable, with an
exception being on the welded piece. If grounding on
the workpiece is intentionally provided using a
protective cable, the connection must be as short as
possible.
The protective cable cross section must be at least as
•
big as the overhead cable of the welding current.
Both cables must be connected to the workpiece in
the same place. Use the grounding terminal on the
appliance or near the appliance.
All safety measures must be taken in a way to
•
prevent any stray current. Check whether the system
voltage corresponds to the input voltage of the
appliance.
Connection of the main feeder cable: The capacity of
•
the circuit breaker or fuses in the main feeder cable
should exceed or be equal to the appliance-absorbed
current I1.
The absorbed current I1 needs to be determined by
reading the technical specifications on the appliance
based on the nominal input voltage U1. All extension
cables must have a cross section corresponding to
the absorbed current I1. Activate the current supply
on the main switch on the back of the appliance.
WARNING:
ELECTRIC SHOCK MAY BE FATAL.
DO NOT TOUCH THE CONDUCTIVE PARTS!
DO NOT TOUCH THE WELDING OUTPUT
CONNECTIONS IF
THE APPLIANCE IS ON!
NEVER TOUCH THE WELDER OR ELECTRODE AND
GROUNDING TERMINAL AT THE SAME TIME!
Select the current based on the electrode diameter,
welding position and welded connection. After welding, it is
necessary to make sure to turn the main switch on and
remove the electrode from the electrode holder.
WIG welding
An appropriate source of gas must be available before
starting your work.

Þ
steel
V2A

stainless steel Þ
Connect the appliance as follows:
Connect your gas bottle with the gas fitting to the
•
appliance (pic. 1/8) using the gas hose (not included)
and secure them with the hose clip.
Connect the WIG hose bundle plug to the appropriate
•
"Dinse bayonet connector" on the inverter (pic. 1/6)
and screw on the WIG hose bundle gas hose (pic.
1/5).
Caution: In WIG welding, the grounding cable is the
anode and the WIG hose bundle is the cathode.
Now insert the grounding cable in the appropriate
-
socket (anode).
