Connection of several wire feed units
The wire feed unit AristoFeed 30--4 or AristoFeed 48--4 with control panel (M0) and the
AristoPendant U8 control unit are to be used when connecting several wire feed units.
Please contact authorised ESAB service personnel when connecting several wire feed
units.
6.3
Overheating protection
The power source is fan cooled and is fitted with a thermal cut--out that trips when
the temperature is too high, this prevents overheating. Resetting takes place
automatically once the power source has cooled.
When this occurs the welding current is interrupted and the orange indicating lamp
on the front of the power source comes on.
6.4
Water flow guard
The water flow guard blocks the power source if the cooling water stops. When this
occurs the welding current is interrupted and an alarm is shown on the control unit.
The water flow guard is an accessory.
6.5
Remote control unit
The program version in AristoPendant U8 should be 1.20 or higher. Aristo mchines
with intergral control panels should have program version 1.21 or higher, in order for
the remote control to function correctly.
When the remote control unit is connected, the power source and wire feed unit are
in remote control mode; the buttons and knobs are blocked. The functions can only
be adjusted via the remote unit.
If the remote control unit is not to be used, the remote control unit must be
disconnected from the power source / wire feed unit, as otherwise it will remain in
remote control mode.
When a remote control unit can set the voltage, the function will change to set the
current with MMA welding.
For more information about the operation of the remote control unit, see the
instruction manuals for the control unit/MMC.
