section, recommended by Solter Soldadura, according to amperage and operating cycle for lengths of less than 25m.
These data are for reference and may NOT suit all applications. If the cable overheats, use a larger cable section:

4 – Connect the MIG torch in its position taking special care to ensure it is tightly screwed. Make sure that the torch is
going to be used is suitable for the current levels and operating cycle that the application requires. You can use an
air-cooled or water-cooled torch.
Do not connect the gas cylinder directly to the wire feeder, as it has no solenoid. The solenoid and the shielding gas
pressure sensor are located in the power unit in order to save gas consumption.
6 - Connect the welding machine to a socket with earth wire (the plug must have an earth connection). Make sure
that the voltage is within the range of 400Vac +/- 15% 3ph. Outside this voltage range, the machine may malfunction.
Aeroprocess 4200 DV machines are supplied with a 4 meters 4x4mm2 power cord without plug. If a longer power cord
is required, it can be replaced.
For lengths of over 25 metres a cable section of 6mm2 is recommended. The machine does not need neutral
connection. The yellow - green cable must always be connected to the machine casing
Installation or replacement of the power cord and the plug should be performed only by qualified personnel.

5 - Connect the gas tube to the rear nozzle of the power unit and the other end
of the tube to the gas cylinder flow regulator. Set the gas flow rate to a typical
value of 8 - 10 l/min. A wrong flow setting can cause defects in the weld bead.
Remember to close the gas bottle valve when you finish welding.
