Configuration; Technical Data - Migatronic MWF 8x Manual De Instrucciones

Introduction
Models MWFx are wire feed units designed for
connection to a MIG/MAG welding power source. All of
the wire feed units are fitted with 4-roll wire drive units
to the wire feed motor by a gearwheel. This ensures
stable feeding of the wire.

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.
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 depending 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.
Dispose of the product according to local
standards and regulations.
