Mains Connection; Connection Of The Mains Plug - Paton StandardMIG-160 User Manual

The welder can be placed and operated outdoors. The internal electrical parts of the
unit are protected against direct exposure to humidity, but not against condensation
droplets.
WARNING! Do not turn off the machine immediately after welding in hot weather or
after intensive welding work in any weather! Allow the electronic components to cool down
within 5 minutes.
WARNING! After using it in cold weather, after turning it off and then cooling
down, condensation forms inside the unit, so it should not be turned on earlier than
3...4 hours!!!
Therefore, do not turn off the unit during cold weather if you plan to turn it on sooner
than 4 hours later.
Place the machine so that there is unobstructed cooling air in and out through the air
vents on the front and rear panels. Make sure that metal dust (e.g. from sanding) is not
sucked directly into the machine by the cooling fan.
WARNING! The unit can be life-threatening after a hard fall. Install on a stable
hard surface.

2.3 MAINS CONNECTION

The welding machine is designed as standard for:
1. 220V mains voltage (-27% +18%) for StandardMIG-160/200/250 models;
2. Three-phase 3x380V or 3x400V (StandardMIG-270-400V/350-400V models), for which
three wires are provided. Safety regulations for working with welding equipment require
grounding the unit's housing. There are two options for this: 1) using the fourth wire in the
yellow-green mains cable (international marking standard); 2) using the bolt terminal on
the rear of the machine (tougher grounding standard, used in CIS countries) in
StandardMIG-270/350-400V models.
Warning! If the unit is connected to mains voltages above 270V (StandardMIG-
160/200/250) or 450V (StandardMIG-270-400V/350-400V), all manufacturer's warranty
obligations will become void!
The manufacturer's warranty will also become null and void if the mains phase is
incorrectly connected to the source ground.
The mains connector, the cross-sections of the power supply cables, as well as the
mains fuses must be selected according to the technical data of the unit.

2.4 CONNECTION OF THE MAINS PLUG

WARNING! The mains plug must be suitable for the supply voltage and current
consumption of the welding machine (see technical data). For safety reasons, use power
sockets with a guaranteed ground connection and never use the neutral wire of the mains
for this purpose!
WARNING! For StandardMIG-160/200/250 models, the mains switch 14 is a signal
button that blocks only the power current of the welding machine, but does not completely
disconnect the internal electronics of the machine. Therefore, as a safety precaution,
remember to unplug completely when connecting.
