Assembly of the welding torch (C-model)
The welding torch is fitted to the central adaptor (pos.
2 page 14), and the connection is fastened by hand.
If the machine has a water module the two water
hoses are fitted to the quick release connectors for
water.
Wire feeding
(C-model)
The wire roll combination to the chosen wire dia-
meter can be seen from the figure page 65. The
machine is delivered with one set of wire rolls etc. as
standard. Other sizes can be delivered. Only parts of
the same colour can be fitted together.
How to connect the separate wire feed unit
(S-model)
The machine is always delivered with a MWF 8 wire
feed unit. The plug kit for the MWF 11/21 wire feed
units can be mounted according the mounting
instructions which can be found together with the
plug kit (please look at page 66).
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.
