GYS NOMADFEED 425-4 Manual Del Usuario página 14

The connection between these two elements is done via one of the following connection cables :
NOMAD CABLE
For longer alternatives, connection cables normally used on traditional MIG/MAG machines will be suitable
INVERTER MIG CONNECTION CABLE
Recommended thickness based on welding current and total length of the welding cable.
Cables length
Less than 30 m (100 ft)
50 m (160 ft)
70 m (230 ft)
100 m (330 ft)
Finally, connect the Nomadfeed earth clamp on the piece to weld.
The case is now ready to be powered. The unit can be powered by an alternative signal higher than 50 or 60Hz between 30 Vrms and 80 Vrms. It
can also be powered by a direct signal between 17dc and 113dc. The polarity of the signal can be positive or negative. Below these minimum values,
Nomadfeed may not power up or not function correctly (welding interruption).
Above these values, Nomadfeed will stop functioning to protect itself and the operator against overvoltage. In that case, the L06 LED lights up and it
will not be possible to weld while the voltage remains too high.
REEL INSTALLATION AND WIRE FEEDING (FIG 4)
Do not wear gloves when setting up the wire and changing the wire reel.
When initially loading the wire through the torch, make sure the torch is as flat and linear as possible and that the nozzle (FIG 4F) and contact tip
(FIG 4E) are removed.
FIG 4A :
• Place the reel on its support :
• Take reel driving force into consideration. To fit a 200 mm (10kg) wire reel, tighten the wire reel support to the maximum.
• Adjust the brake (FIG 4A-2) to avoid the wire getting tangled when the weld stops. In general, do not excessively tighten the brake, which would
cause the motor to overheat.
FIG 4B :
It is essential that the rollers match the type of wire used. The 2 top pressure rollers (diam.30mm) are different to the 2 bottom drive rollers
(diam.37mm) (FIG 4B). It is therefore necessary to check all 4 rollers before feeding the wire through.

Adjust the pressure on the pressure rollers using the 2 adjusting wheels (FIG 4C-4). The pressure level needs to allow the wire to feed through the
torch without being slowed by the rollers. However, when the wire hits the welding area, the rollers must be able to skid on the wire without it get-
ting tangled when leaving the wire feed motor. When using soft wire such as aluminium, copper alloys or cored wire, if the pressure is too high it will
deform the wire . The use of the setting «2» is recommended.
To use 1.6mm wire, it is necessary to remove the brass capillary tube located in the Euro connector (Pic 4C-5).
