Adjustment of wire brake
The wire brake must ensure that the wire reel brakes sufficiently before the
welding wire runs over the edge of the reel. The brake force is dependent on
the weight of the wire reel and wire feed speed.
Factory setting is 15kg.
Adjustment:
•
Dismount the control knob by placing a
thin screw driver behind the knob and
thereafter pull it out.
•
Adjust the wire brake by fastening or
loosening the self-locking nut on the axle
of the wire hub.
•
Remount the control knob.

Connection of shielding gas
Connect the gas hose, which branches off from the
back panel of the welding machine (3), to a gas
supply with pressure regulator (2-6 bar).
(Note: Some types of pressure regulators require
an output pressure of more than 2 bar to function
optimally).
One/two gas cylinders can be mounted on the bottle
carrier on the back of a trolley if any.

Gas consumption
Depending on the welding task, gas type and seam
design, the gas consumption will vary in ranges
from 6-7 l/min at low amperages (<25A) and up to
27 l/ min at max. amperage.
Material consumption
Material consumption can be estimated by
calculating welding time in minutes times wire
feed speed (m/min) times weight per meter of the
welding consumables in use.
Inching CMI 273i/223i TWIN
The function is used for
wire inching e.g. after
change of wire.
Inching CMI 183i/223i
Wire inching starts by
pressing the green key
pad and simultaneously
triggering the
torch trigger.
Wire inching
continues even
though the green key
pad has been released.
It does not stop until the torch trigger has been
released again.
