PATON Standard DC MMA
INSTALLATION REQUIREMENTS
The machine must be placed so as to ensure free inlet and outlet of cooling air through vent holes on the front and the rear panels. Take
care that metal dust (for example, during emery grinding) does drawn directly into the machine by the cooling fan.
POWER CONNECTION
The welding machine of series design is rated for three-phase mains voltage is 3x380V or 3x400V, three wires are dedicated for this.
Safety rules when working with welding equipment require grounding of the unit housing. There are two ways to do this: 1) by using
the fourth wire in the mains yellow-green cable (international marking standard); 2) by using a bolted terminal on the rear wall of the
unit (a stricter grounding standard, used in the CIS countries).
CAUTION!
When the unit is connected to a mains voltage higher than 450V, all manufacturer's warranty obligations become invalid!
The manufacturer's warranty obligations also become invalid in case of an erroneous connection of the mains phase to the sour ce
ground.
Mains connector, cross‐sections of power supply cables and supply‐line fuses must be se lected on the basis of technical specifications of
the machine.
