3. OPERATING CONTROLS
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.
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. 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.
5. 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.
6. All interventions in the el. equipment as well as repair (removal of the plug,
fuse replacement) should be performed by an authorized person.
7. With competent mains voltage and input must match the plug.
Caution
Extension cables must not have conductors with a smaller
cross section than 4x2,5 mm
2
(for machine PEGAS 320 AC/DC PULSE) and
4x4 mm
2
(for machine PEGAS 400 AC/DC PULSE). The machine can be
operated on a three-phase electric generator 19 kVA – for PEGAS 320
AC/DC PULSE (for PEGAS 400 AC/DC PULSE 25 kVA) (3x400V/50Hz) and
more, which has ensured voltage stabilization ± 10%. Generators with
lower power can damage the machine.
8. It is necessary to protect the machine against:
a. Moisture and rain
b. Chemically aggressive environments
c. Mechanical damage
d. Draft and possibly ventilation of neighboring machines
e. Excessive overloading – exceeding tech. parameters
f. Rough treatment
