3. OPERATING CONDITIONS
1. Putting the machine into operation can be performed only by trained
personnel and only within the technical provisions. he 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.
3. he 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. he 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.
5. Handling handle is intended for movement, it is not designed to lifting the
machine.
6. In case of overheating of the machine welding is automatically stopped and
this condition is signalized by pilot light.
7. All interventions in the el. equipment as well as repair (removal of the plug,
fuse replacement) should be performed by an authorized person.
8. With competent mains voltage and input must match the plug.
9. Do not use the machine for other purposes, such as defrosting pipes, starter
source, etc.
10. 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.
11. he 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).
12. 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
e) Rough treatment
f) Chemically aggressive environments
ELECTROMAGNETIC COMPATIBILITY
he welding device is in terms of interference designed primarily for industrial
areas. It meets the requirements of EN 60974-10 class A and it isn’t designed
for using in residential areas, where the electrical energy is supplied by public
low-voltage power supply network. It can be here potential problems with
ensuring of electromagnetic compatibility in this areas, due to interference
caused by power lines as well as the radiated interference. During operation, the
device may be the source of interference.
