1.2 About FastMig products
Kemppi FastMig™ MXF 63, MXF 65 and MXF 67 are wire feeders designed for demanding
professional use. MXF 63 is intended for 200 mm wire spool, MXF 65 and MXF 67 for 300 mm
wire spool. Wire feeders can be used with FastMig Pulse, FastMig KMS and FastMig M power
sources.
Which alternative panel to choose for MXF 63, 65 and 67 depends on the used power source
i.e. FastMig KMS becomes compatible by connecting SF 51, SF 52W, SF 53W or SF 54 control
panels with MXF wire feed unit, and in the case of PF 63 and PF 65 control panels FastMig
Pulse power source can be connected. With FastMig M the MR 200, MR 300, MS 200 or MS 300
panels are used. Operation of wire feed units is controlled and adjusted by microprocessor. By
adding an optional synchronization unit (MXF Sync 65), SuperSnake sub-feeder device may be
connected to MXF 63, 65 and 67.
This manual provides instructions on the start-up and use of the MXF 63, 65 and 67 MIG/MAG
wire feeding units.

2.3 Assembly of MIG/MAG system
Assemble the units in the order mentioned below. Follow the additional mounting and
operating instructions delivered with each package.
1. Installation of power source
Read paragraph: ”Installation” in the operation instructions for FastMig power sources, and
complete the installation according to that advice.
2. Mounting of power sources to transport wagon
Read and follow the instructions given in the transport cart installation/assembly manual.
3. Mounting the FastMig MXF wire feed unit to the power source
Remove the cover sticker on top of the power source. Screw the fastening pivot into the
power source – hand tighten only. Place the supplied plastic spacers over the pivot. Lift the
MXF wire feeder into place, locating over the pivot.
4. Connecting cables
Connect the cables in accordance with the equipment notes provided in this manual.
The polarity of the welding wire (+ or –) can be selected by connecting the wire feed unit to
either the positive or the negative power source terminals.
Most MIG/MAG applications run the wire feed unit connected to the positive terminal of the
power source.
5. Mounting FastMig wire feed units to boom and swing arms
When mounting wire feed units to boom and swing arms, the unit must be electrically
isolated from both.
Suspension angle of wire feed unit can be changed by moving the xing point in handle.

2.4 Accessories corresponding to wire diameter
Colour coded wire feed rolls and guide tubes are available to suit a variety of ller wire types
and sizes. Drive roll groove geometry and design vary depending on the application. Further
details are available in the spare part tables.
Please ensure you select the correct drive rolls and guide tubes from the table to suit your
particular welding application.
2.5 Welding gun selection
Please ensure that the welding gun selected is suitable for the target application. Check the
gun manufacturer's specication and ensure the gun meets the welding duty requirements.
Also consider the extra heating eects of Pulse MIG/MAG welding on the gun selected.
Kemppi gun products are designed to meet many dierent applications. Special wire liners
and contact tips are available for dierent wire types and sizes.
Distance wire feeding is accommodated with WeldSnake and SuperSnake products in either
air or liquid cooled models.
Thermal and load protection is also designed to some Kemppi Gun models and feed units, so
carefully consider your requirements and consult your local Kemppi sales team to ensure you
choose the correct alternative for your needs.
2.6 Mounting and locking of wire spool
EN
NOTE! Check that the ller wire spool is correctly mounted and locked into position. Ensure the
spool is not damaged or deformed in such a way that it can rub or cha against the internal
surface of the wire feed unit chassis or door. This may result in increased drag, impacting on weld
quality. This may also result in long term wire feed unit damage, rendering the unit unserviceable
or unsafe to use.
Automatic wire feed makes wire spool changes faster. When changing the wire spool, the
pressure of feed rolls need to be released.
Simply ensure that the groove of the feed roll matches the diameter of ller wire used. Release
the wire end from the spool and cut o any deformed section. Be careful the wire does not
spill from the spool sides.
Straighten about 20 cm of ller wire and ensure the tip has no sharp edges. File if necessary, as
a sharp wire edge may damage the wire gun liner - particularly softer plastic liners.
Present the ller wire tip to the back of the wire feed rolls and press the Wire Inch button on
the wire feed panel or use the switch inside the wire spool cabinet. Feed the wire to the gun
contact tip and prepare to weld.
NOTE! Smaller diameter ller wires may need to be loaded manually – with the feed roll pressure
arms released. This is because it is easy to overestimate the pressure required to feed these smaller
ller wires. Too high feed roll pressures can easily deform ller wires and contribute to later feeding
problems.
