Connection to power source
The wire feed unit MWF 55
2
YARD is designed for
connection to the MIGATRONIC power source
SIGMA
2
.
Configuration
MIGATRONIC disclaims all responsibility for damaged
cables and other damages related to welding with
under sized welding torch and welding cables
measured by welding specifications e.g. in relation to
permissible load.
Dispose of the product according to local
standards and regulations.

Important!
In order to avoid destruction of
plugs and cables, good electric
contact is required when connecting
earth cables and intermediary
cables to the machine.
Adjustment of wire brake
The wire brake must ensure that the wire reel brakes
sufficiently quickly when welding stops. The required
brake force is dependent on the weight of the wire reel
and the maximum wire feed speed. A brake torque of
1.5-2.0 Nm will be satisfactory for most applications.
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 knob by pressing it back into the
groove.
