3. OPERATING CONDITIONS
1. Putting the machine into operation can be performed only by trained
personnel and only within the technical provisions. The manufacturer is not
liable for damages resulting from improper use or handling. For
maintenance and repair, use only original spare parts from ALFA IN.
2. Device complies with IEC 61000-3-12 with following conditions:
Short-circuit power S
sc
of network in place at an interface between the
user's supply and the public network (PCC) must be least 4106 kW.
User is obliged to consult with the electricity supplier if the impedance of
the network at this point is that required short-circuit capacity Z
max
= 36 mΩ
and whether the device can be connected with a public low-voltage
network.
On the nameplate are the following symbols:
.
3. The welding machine is tested according to the degree of protection IP
23S, which provides protection against the intrusion of solid bodies with a
diameter greater than 12 mm and protection against ingress of water,
falling on the machine in a vertical direction or max degree of 60°.
4. Working ambient temperature between -10 and +40 °C.
5. Relative humidity below 90% at +20 °C.
6. Up to 3000 m altitude.
7. The machine must be positioned so that cooling air can enter and leave
through cooling vents with no problem. It is necessary to ensure that there
are no mechanical equipment, especially metal particles (e.g. during
grinding) drawn into the machine.
8. Handling handle is intended for movement, it is not designed to lifting the
machine.
9. In case of overheating of the machine welding is automatically stopped
and this condition is signalized by pilot light.
10.
All interventions in the el. equipment as well as repair (removal of the
plug, fuse replacement) should be performed by an authorized person.
11.
With competent mains voltage and input must match the plug.
12.
Do not use the machine for other purposes, such as defrosting pipes,
starter source, etc.
13.
It is necessary for welding machine to undergo a periodic inspection
every 6/12 months by an authorized officer according to ČSN 331500 and
ČSN 050630 – see Maintenance and service tests.
14.
The welding machine is designed especially for industrial areas. In
case of using it in other areas there may exist special measures (see EN
60974-10).
15.
It is necessary to protect the machine against:
a. Moisture and rain
b. Mechanical damage
c. Draft and possibly ventilation of neighboring machines
d. Excessive overloading – exceeding tech. parameters
