Kemppi ArcFeed A voltage sensing wire feeder for MIG/MAG
welding. A way to transform existing MMA power sources to
MIG/MAG
equipment. A small investment but a big step towards
productivity. Three models available. One for 200mm and two for
300mm
wire spools. Model 300P with more effective wire drive for
welding with thick
wires.
-
Operation ?Kemppi Arc Feed is designed to operate with both CC
(constant current) and CV (constant voltage) power sources.
Operation with power source with CC characteristics? When using
with CC type of power source, changes the wire feed speed according
to the arc voltage. This feature makes arc voltage more
stabile.
Operation with power source with CV characteristics? The CV type
of power source is more stabile (voltage regardless of the
amperage). It results in a flat volt-amp curve. Wire feeder is not
making any adjustments during welding (like wire feed speed). The
MIG/MAG welding machines are typically CV type machines.

Adjusting the welding parameters
CC mode: In CC mode the display shows the open-circuit voltage
and a
reference value for welding current on the display. The
reference value has been determined by using 1.2 flux-cored
wire.
Before starting to weld, use the control knob to set the
weldingcurrent to match that of the power source.
NOTE: When welding in CC mode, the dynamics setting in the
powersource must be at its maximum value.
With the control knob you choose the welding values in the
following way:
-
Adjusting the welding parameters
CV mode: In CV mode the display shows the welding voltage and
wire feed speed,
which is in the range of 0-18 m/s (small drive roll) or 0-25
(large drive roll).
Before starting to weld, check the correct values for voltage
and wire feed speed in the settings table, and use the control knob
to enter the necessary settings in the feeder for wfs and in the
power source for voltage and current, if available.
With the control knob you choose the welding values in the
following way:
