3. INSTALLATION
3.1 Assembly of MIG system
Assemble the units in order mentioned below and follow mounting and operation
instructions which are delivered in packages.
Installation of power source
Read paragraph: ”Installation” in operation instructions for FastMig power sources and carry
out the installation according to that.
Mounting of KM power sources to transport wagon
Read and follow the instructions given in the transport cart installation/assembly manual
Connecting cables
Connect the cables in accordance with the equipment notes provided.
The polarity of the welding wire (+ or -) can be changed by replacing the MF welding current
cable and return current cable with the FastMig™ power source welding cable connector.
Mounting of FastMig wire feed units to boom
NOTE! Wire feed unit must be mounted to boom in such a way that its chassis is galvanic separated
both from swing arm and boom.
Suspension angle of wire feed unit can be changed by moving xing point in handle.
3.2 Mounting of MIG welding gun
In order to ensure trouble-free welding check in operation instructions of gun used by you
that wire guide tube and contact tip of gun are according to manufacturer’s recommendation
suitable to be used for wire feed diameter and type in question. To tight a wire guide tube
might cause for wire feed unit a bigger stress than normally as well as disturbances in wire
feed.
Screw snap connector of gun tight that there won’t come any voltage losses on connecting
surface. A loose connection will heat gun and wire feed unit and feeder.
3.3 Mounting and locking of wire spool
A
B
• Release the locking nut (A)!
• Mount the spool at its place. Note rotating direction of spool
• Lock the spool with locking nut.
NOTE! Check that in ller wire spool there are no parts sticking out, which could e.g. chafe against
chassis or door of wire feed unit. Dragging parts might expose chassis of wire feed unit under
voltage.

FastMig MF 29
3.4 Automatic wire feed to gun
Automatic wire feed makes change of wire spool more rapid. In spool change the pressure of
feed rolls need not to be released and ller wire goes automatically to correct wire line.
• Make sure that groove of feed roll matches the diameter of welding wire used.
• Release the wire end from spool and cut o the bent length. Be careful that the wire
does not spill from the spool to sides!
• Straighten about 20 cm of the wire and see that the end of it has no sharp edges (le
o if necessary). A sharp edge may damage the wire guide tube and contact tip of the
welding gun.
• Draw a bit of loose wire from wire spool. Feed wire through back liner to feed rolls. Do
not release pressure of feed rolls!
• Press the gun switch and feed wire until wire goes through feed rolls to gun. See that
wire is in grooves of both feed roll pairs!
• Press still the gun switch until wire has come through contact tip.
Automatic feed may sometimes fail with thin wires (Fe, Fc, Ss: 0,6 – 0,8 mm, Al: 0,8 – 1,0 mm).
In that case you might have to open feed rolls and feed wire manually through feed rolls.
3.5 Adjustment of pressure
Adjust the pressure of feed rolls with the control screw (20) so that the wire is fed into the wire
guide tube evenly and allows a little braking when coming out from the contact tip without
slipping at the feed rolls.
NOTE! Excessive pressure causes attening of the ller wire and damage to the coating. It also
causes undue wear of the feed rolls as well as friction.
EN
3.6 Adjustment of tightness of spool brake
A
B
Brake force is adjusted by screwing the adjusting nut (B), tightening clockwise direction.
Adjust brake force as so big that the wire is not allowed to become too loose on the spool so
that it would spill from the spool when the rotation of the spool stops. Need for brake force is
increased with increase of wire feed speed.
Since the brake loads for its part the motor, you shouldn’t keep it unnecessarily tight.
3.7 Burn back time
Electronics of feed unit controls stopping of welding automatically so that the wire end
doesn’t melt fastened to the contact tip or the work piece. Automatics work regardless of the
wire feed speed. Can be adjusted also from power source SETUP-menu ('PoC').
3.8 Ground cable
Connecting of earth cable should be preferably connected directly to the welding material.
Contact surface of press always should be as large as possible.
Clean the fastening surface from paint and rust!
Use in your MIG equipment at least 70 mm². Thinner cross-sectional areas might cause
overheating of connectors and insulations.
Make sure that the welding gun in your use is designed for max. welding current needed by
you!
NOTE! Never use a damaged welding gun!

3.9 Shielding gas
NOTE! Handle gas cylinder with care. There is a risk for injury if the cylinder or its valve is damaged!
For welding stainless steels, mixed gases are normally used. Check that the gas cylinder valve
is suitable for the gas. The ow rate is set according to the welding power used in the job. A
suitable ow rate is normally 8 – 10 l/min. If the gas ow is not suitable, the welded joint will
be sporous. Contact your local Kemppi-dealer for choosing gas and equipment.
3.9.1 Installing gas cylinder
NOTE! Always fasten gas cylinder properly in vertical position in a special holder on the wall or on a
carriage. Remember to close gas cylinder valve after having nished welding.
Parts of gas ow regulator
EN

A. Gas cylinder valve
B. Press regulation screw
C. Connecting nut
D. Hose spindle
E. Jacket nut
F. Gas cylinder pressure meter
G. Gas hose pressure meter
The following installing instructions are valid for most of the gas ow regulator types:
1. Step aside and open the cylinder valve (A) for a while to blow out possible impurities
from the cylinder valve.
2. Turn the press regulation screw (B) of the regulator until no spring pressure can be felt.
3. Close needle valve, if there is one in the regulator.
4. Install the regulator on cylinder valve and tighten connecting nut (C) with a wrench.
5. Install hose spindle (D) and jacket nut (E) into gas hose and tighten with hose clamp.
6. Connect the hose with the regulator and the other end with the wire feed unit. Tighten
the jacket nut.
7. Open cylinder valve slowly. Gas cylinder pressure meter (F) shows the cylinder pressure.
Note! Do not use the whole contents of the cylinder. The cylinder should be lled when
the cylinder pressure is 2 bar.
8. Open needle valve if there is one in the regulator.
9. Turn regulation screw (B) until hose pressure meter (G) shows the required ow (or
pressure). When regulating ow amount, the power source should be in switched on and
the gun switch pressed simultaneously.
Close cylinder valve after having nished welding. If the machine will be out of use for a long
time, unscrew the pressure regulation screw.

closest to this switch will light up, indicating the power source is ready for welding.
NOTE! Always start and switch o the machine with the main switch, never use the mains plug as a
switch.
3.11 Operation of cooling unit, FastCool 10
Operation of cooling unit is controlled in such a way that pump is started when welding is
started. After welding stop pump is rotating for approx. 5 min cooling the gun and the cooling
liquid to ambient temperature.
Read in operation instructions for the FastCool 10 unit the trouble situations of the liquid
circulation system and protection against torch etc. damage.
3.12 Hanging
MF 29 can be hanged to the barrier with an optional hanging frame (6185285). The machine is
not supposed to be hanged from its handle.
4. SERVICE, OPERATION DISTURBANCES
The amount of use and the working environment should be taken into consideration when
planning the frequency of maintenance of MF. Careful use and preventive maintenance will
help to ensure trouble-free operation.
EN
The following maintenance operations should be carried out at least every six months:
Check:
• The wear of the grooves of the feed rolls. Excessive wear of grooves causes problems in
wire feed.
• The wear of the wire guide tubes of wire feed. Badly worn feed rolls and wire guide tubes
should be discarded.
• The wire guide tube in the gun should be set as near the feed rolls as possible, but not
touching them and the wire must follow a straight line from the end of the tube to the
groove of the feed roll.
• Spool brake adjustment.
• Electric connections
- Oxidised couplings must be cleaned
- Loose couplings must be tightened
Clean dust and dirt from the equipment.
NOTE! When using compressed air, always protect your eyes with proper eye protection.
In case of problems contact your KEMPPI dealer.
