Starting Up; Electrical Connections To The Mains; Connection Of The Wire Feeder Unit; Connection Of The Torch And Cooling Unit - Air Liquide SAF-FRO DIGIWAVE II Instruction For Operation And Maintenance

2 - STARTING UP

Refer to the provided Quick Start literature for details on the several steps for the installation of the DIGIWAVE II.

2.1. ELECTRICAL CONNECTIONS TO THE MAINS

DIGIWAVE II is a 400 V 3-phase welding set.
If your mains supply corresponds to requirements, connect the "three-phase + ground" plug to the end of the power cable.
DIGIWAVE II is compatible with the following generator sets:
Version 420 : 27 KVA generator mini
Version 520 : 40 KVA generator mini
ALW recommends using SDMO generator.
The electrical connection of the power source must be done by qualified persons and the power supply installation must be correctly
dimensioned regarding the characteristics of the power source (especially concerning the maximum consumed current).
This equipment does not comply with IEC 61000-3-12. If it is connected to a public low voltage system, it is the responsibility of the
installer or user of the equipment to ensure, by consultation with the distribution network operator if necessary, that the equipment may be
connected.
This Class A equipment is not intended for use in residential locations where the electrical power is provided by the public low-voltage
supply system. There may be potential difficulties in ensuring electromagnetic compatibility in those locations, due to conducted as well
as radiated disturbances.

2.2. CONNECTION OF THE WIRE FEEDER UNIT

Refer to the operating manual of the Wire Feeder and the Quick Start.
This must be carried out with the power source power off. The power plugs must be well tied up their tightening must be regularly
controlled, in particular after the moving of an installation.

2.3. CONNECTION OF THE TORCH AND COOLING UNIT

Refer to the operating manual of the torch and the Quick Start literature.
The MIG welding torch is connected to the front of the wire feeder, after ensuring it has been properly outfitted with the wear parts corresponding to the
wire used for welding.
If you use a WATER-COOLED torch, make sure to connect your cooling unit to the rear of the power source, as well as to the "water" harness.
WARNING:
Use exclusively the liquid provided by Air Liquide Welding to fill up the cooling unit.
Configuration on the interface is needed to ensure a good working of the cooling unit, cf § 6.1.
No-load operation of the cooling unit while unconnected to a torch may damage it.

2.4. GAS INLET CONNECTION

.
Refer to the Quick Start
The gas hose is linked to the harness connecting the power source to the wire feeder. Simply connect it to the pressure-regulator outlet of the gas
cylinder.
Place the gas cylinder on the trolley at the rear of the power source and fasten the cylinder using the strap.
Open the cylinder valve slightly to allow existing impurities to escape and then reclose it.
Mount the pressure regulator/flow meter
Connect the gas hose supplied with the wire feeder harness to the regulator's outlet
Open the gas cylinder.
During welding, the gas flow rate (l/min) should correspond to the diameter of the nozzle (mm).
Make sure the gas cylinder is properly secured on the trolley by attaching the safety strap.
