VDI SERIES MINI DC MMA
For ensuring the operability of the welding unit for a long-term service life, it is necessary to perform
the following procedures:
1.
Periodically, at specified time intervals, check that the safety requirements in operation of the
welding unit are met (see
Section 11
, "Safety instructions").
2.
At half-yearly intervals, if the unit is intensely operated, purge the welding unit with dry
compressed air. Warning! Purging the welding unit with compressed air at a short distance may
result in damage of the electronic elements of the unit.
3.
When operating the welding unit in environment with excessive dust content, manually clean
the unit passages for cooling air.
ATTENTION!
Purging of the unit from a short distance can result in damage
of the electronic elements of the unit.
5. OPERATION WITH AN ELECTRIC GENERATOR
The welding unit can operate with power supply from an electric generator if the following conditions
are satisfied:
Electrode diameter (mm)
Set welding current (A)
Minimum power
of the generator (kVA)
Ф
2
not more than 80А
2.6
Ф3
not more than 120А
4.1
Ф4
Up to 150А
5.0
ATTENTION!!!
The output voltage of the electric generator must be in the
range of 170
–
260 V. The manufacturer suggests the use of a generator set
with the AVR system responsible for voltage stabilization
.
6. STORAGE
The preserved and packed welding unit can be stored according to GOST 15150-69 for 5 years.
The welding unit should be stored in a dry closed room at an ambient temperature not lower than 5 ºC.
In the room, vapors of acids and other chemically active substances must not be present.
7. TRANSPORTATION
The packed welding unit can be transported by any means of transport which ensure the integrity of
the unit and compliance of the unit with the shipping rules established for the specified transport
means.
8. SPECIFICATION DATA
ATTENTION!!!
If the welding unit is rated for a special power supply
voltage, the specification data of the unit are indicated on the nameplate on the
upper or rear panel of the unit. In this case, the electrical outlet of the power
supply system and the power cable of the welding unit should be selected with
consideration for the actual power supply voltage.
