WARNING!!!
When connecting the welding unit to an electrical outlet (at a
temperature of 25 ºC) of a power supply system, it is necessary to consider
wall-buried wiring and the lengths of extension cables.

1. GENERAL INFORMATION
Inverter rectifiers
PATON™ VDI-160E, VDI-200E, VDI-250E
optimized for direct-current
manual arc welding
(MMA)
. This
“ECO”
series of devices designed for demanding users who wants
the most compact and functional device on its full rated current of 160A / 200A / 250A, respectively. It
is more than enough for most works with electrodes from
Ф
1,6 mm to
Ф
5 mm (including refractory),
while operating load factor is not less than 40%, which is more than enough for most works in
household sector (workshops, fleets, etc.).
The block for protection of overvoltage and undervoltage is installed in all
Paton™
MMA
branded
models.
Due to the increased frequency of the input voltage of the rectifier transformer of the welding unit, the
weight and overall dimensions of the transformer are significantly reduced as compared with other
welding units with similar characteristics.
