If a supply hose longer than 5 metres should be required, you should replace the existing hose with
another one whose section must be chosen according to the preceding table.
Any supply voltage that is outside the rated margin gives rise to the activation of the protection system,
preventing the welding operation.

This cable has four wires, three of which are connected to the mains and the other (yellow, with green border) must be
connected to the earth intake of the plug. In the above figures are described the connection of the intake hose to the two
most common types of standardised plug (IEC 309-2). In this figure L1, L2 and L3 show the phase cables and PE
represents the earth protection conductor.
