• Wire feed
This monitoring channel measures the actual wire feed speed at the wire
drive rollers. Prerequisite: A corresponding pressure roller with encoder
function is mounted in the QN-WF-XX wire feed unit.
• Current
This monitoring channel measures the arithmetic average value of the
welding current.
• Voltage
This monitoring channel measures the arithmetic average value of the
welding voltage.
• Gas
This monitoring channel measures the actual gas flow quantity in the gas
flow sensor.
• Motor current QWD
This monitoring channel measures the arithmetic average value of the
motor current at the QWD wire drive unit. The set value is constant and
cannot be configured.
• Motor current CDD
This monitoring channel measures the arithmetic average value of the mo-
tor current at the CDD ROB wire drive unit. It may be an indication that the
QWD feed capacity is too high if the measured value is below the set value.
So the CDD ROB wire drive unit slows down. It may be an indication that
the QWD feed capacity is too low or the friction of the wire feed distance
is higher if the measured value is above the set value. So the CDD ROB wire
drive unit accelerates.
• WCM
The circuit generates a signal from the current and voltage curve which
allow conclusions regarding the arc quality. The further processing of the
signal produces a level which operates in a defined area if the arc is cor-
rectly adjusted.
The level of the WCM module changes if the arc is interfered with external
influences such as impurities, paint, oil etc.
The WCM function is optional. It is not included in the standard scope of
supply of the Qineo welding power sources!
• Reserve1* / Heat input
For this monitoring channel two states are available for selection.
The following applies to both states:
By pressing the middle rotary knob the speed for entering data is changed
(x10, x100, x1000).
