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.
Note: CMI 183i/223i
Torch adjustment (Dialog torch)
The welding current, wire feed speed or thickness
of material can be adjusted both from the machine
and the welding torch if a welding hose with dialog
torch is in use. The torch adjustment is passive
without Dialog torch.
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.
