VDI SERIES MINI DC MMA
For this reason, do not switch off the welding unit if it is anticipated that the unit is to be switched on
not later than 4 hours after switching off.
Install the welding unit so as not to block or cover the ventilation slots on the front and rear panels of
the unit. Prevent ingress of metallic particles (for example, when grinding the weld) sucked into the
welding unit by the unit ventilator.
ATTENTION!!!
After fall from a height, the welding unit might be a source
of electrical shock. Install the unit on a firm stable surface.
2.3 CONNECTION TO A POWER SUPPLY SYSTEM
The commercial welding unit is rated for an input power supply voltage of 230 V (- 26% / +13%).
ATTENTION!!!
If the welding unit has been damaged in the result of
increase of the input power supply voltage of the welding unit to more than 270
V, possible in the case of large unbalance of phase voltages in the standard
power supply system, the warranty of the manufacturer of the welding unit will
be invalid.
The power supply connector, cross-section areas of the power cable conductors, and power supply line
fuses should be selected with consideration for the technical characteristics of the welding unit.
2.4 REQUIREMENTS FOR AN ELECTRICAL OUTLET
ATTENTION!!!
The parameters of an electrical outlet for the power supply
of the welding unit must correspond to the power supply voltage and
consumption current of the unit (see "Technical characteristics"). Connect the
welding unit to an electrical outlet that is rated for a three-wire plug with a
grounding conductor!!!

of the welding unit;
2.
Insert the plug of the grounding cable into socket
B (-)
of the welding unit;
3.
Connect the grounding cable to the workpiece;
4.
Connect the power cable of the welding unit to the outlet of the power supply
system;
5.
Set switch 3 to position 1 (switching on).
6.
The device is ready for use. Enjoy Your work.
