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 the 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 (- 30%/+13%)
ATTENTION!
The manufacturer's warranty is no longer valid if a single-phase
device is connected to a power supply voltage of over
270 V
, and three-phase to
460
V
. This situation can occur if the phase voltages in the standard power system are
unbalanced or if you use a non-standard connection.
The power supply connector, power cable cross-section area, and 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 welding unit
(see Section 1.1, "Technical characteristics")
.
Connect the welding unit to an electrical outlet that is rated for a three-wire plug
with a grounding conductor
.
