ATTENTION
DANGER OF ELECTRIC SHOCK! Consider working area
environment. Do not expose power tools to rain. Do not use
power tools in damp or wet locations. Keep work area well lit
and dry. Try to prevent the device from getting wet or being
exposed to humidity. Do not leave it outside overnight. Water
entering a power tool will increase the risk of electric shock.
•
The power supply cable should be checked regularly and,
before using it, make sure the cable is not damaged or worn out.
If the cable is not in good condition, do not use the appliance;
take it to an authorized service centre.
•
When tool is used outdoor, only use an extension cable that
is suitable for outdoor use and which is marked for this specific
use. Keep it away from the working area, from damp, wet or oily
surfaces and away from heat and flammable materials.
•
Avoid any accidental starting: make sure that the power
switch (if present) is in the «off» position, before plugging the
tool in.
•
Remove adjusting keys or wrenches before turning the tool
on.
•
Do not use the tool if the switch does not turn the tool on
or off. Any tool that cannot be controlled with the switch is
dangerous and must be repaired.
WARNING
During the use of power tools, some dust containing chemicals
known to cause cancer, may occur. Some of these chemicals are:
lead from lead based paints, crystalline silica from bricks and
cement and other masonry products, arsenic and chromium
from chemically treated lumber and other dangerous products. If
dust is present, your risk from these exposures varies, depending
on how often you do this type of work. To reduce your exposure
to these chemicals, any time you do pulverulent operations,
work in a well ventilated area and work with approved safety
equipment, such as dust masks that are specially designed to
filter out microscopic particles.
•
If the appliance strikes a foreign body, examine the device
for signs of damage and carry out any necessary repairs before
restarting and continuing to work.
•
If the appliance starts to vibrate abnormally, turn it off
and check for the cause immediately. Vibration is generally a
warning of trouble.
•
Always switch off the appliance and wait until the device
completely stops whenever you leave the machine, before
carrying out maintenance, before checking, cleaning or working
on the appliance.
•
It is forbidden to move or modify any of the internal parts
of the device.
Specific safety rules
•
Make sure the working area is adequately ventilated.
Welding machine is light and compact. Natural wind is not
enough to cool down components. There is an axial-flow fan in
the machine in order to force it to cool down.
•
No over-load! Limit the welding current strictly according
to max allowable current during all kinds of duty cycles. Do not
exceed load working in order to prevent shorting.
•
No over-voltage! Power voltage of the welding machine is in
accordance with the technical data sheet. The compensation of
the circuit of voltage is automatic and may ensure that welding
current will not exceed to allowable volume. If power voltage
exceeds the allowable volume, it may damage the components.
Please be careful.
•
Once power is connected, make sure to coordinate contact
of power or socket and make sure the elements don't get
oxidized.
•
Make sure secondary output electrode is connected.
•
Check if all contacts are connected firmly, specially between
the grounding cable clamp (12) and the work piece.
•
Spatters from the machine can cause fire, so make sure
there isn't any combustible substance near the working area.
(IWM-100)
•
There is a grounding screw behind the machine which is
marked with "Ground". The mantle must be connected reliably
by a cable whose section is 10mm2.
(IWM-180)
•
This machine is designed in accordance with the EN60974-1
safety standards, with single-phase input voltage and DC output
current.
Unpacking
When unpacking, check to make sure that all components are
included. Refer to the drawings on this manual. If any parts are
missing or broken, please call IVT assistance center.
Controls explanation
•
Positive quick plug (1): generally used to connect the
welding cable (8);
•
Negative quick plug (2): generally used to connect the
return cable (9);
•
Current regulation knob (3): is a stepless potentiometer to
regulate welding current with graduated scale (IWM-100; IWM-
180) or with a current display (IWM-200);
•
Power light (5): when it is on, machine is ready to work;
•
On/Off switch (6): general switch;
•
Current display (14): it is used to set the precise current
value;
•
AC input terminal (7): mains cable;
•
Abnormal working light (4): normally off, when on it means
that the welding current cannot flow due to one of the following
faults:
•
Thermal protection: inside the machine the temperature is
excessive. The machine is on but does not deliver current until a
normal temperature is reached;
•
Overcurrent protection:
unstable.
