4. ASSEMBLY OF KEMPOWELD EQUIPMENT
Kempoweld power source: Read chapter “Installation” in the Operation Instructions of the power source.
Wire feed unit:
1. Mount wire feed unit on the pin on the power source cover.
2. Mount control cable and welding current cable to the connectors to the rear walls and return current cable
to the connector on Kempoweld front panel.
3. Welding current polarity: When the connection has been done according to the markings, the gun has positive
voltage. In order to change polarity, interchange the welding and return current cable ends connection to the
power source.
4. Connect the interconnection cable plugs with the corresponding sockets in units.
5. If the wire feed unit is mounted to boom, it may not have galvanic contact with lift hook and boom.
6. MIG-gun is connected with EURO connector. Use guide tubes and contact tips according to manufacturer´s
operation instructions. Accessories which are too tight or otherwise unsuitable for the wire type used, will
cause disturbances and excessive stress on accessories.

5.1. ACCESSORIES CORRESPONDING TO WIRE DIAMETER
Feed rolls
colour filler wire ø mm (inch)
white 0.6 and 0.8 (0.030)
red 0.9/1.0 and 1.2 (0.035, 0.045 and 0.052)
Guide tubes
colour filler wire ø mm (inch)
white 0.6 and 0.8 (0.030)
orange 0.9-1.6 (0.035, 00.45 and 0.052)
The wire feed rolls have two grooves for different filler wire diameters. Correct wire groove is chosen by moving
selecting washer from one side of feed roll to another. The feed rolls and wire guide tubes of wire feed unit have
colour codes in order to make identification easier (see table on page 4). On delivery the Kempoweld WIRE 200 is
equipped with red feed rolls with plain groove and with orange wire guide tubes for welding filler wires of 0.9-1.2
mm (0.035", 0.045" and 0.052").
5.2. INSTALLING MIG WELDING GUN
To ensure problem-free welding, check in the Operation Instructions of the gun that the wire guide tube and contact
tip are in accordance with the manufacturer´s recommendation, and suitable to be used for wire feed diameter
and type in question. An overly tight wire guide tube may cause excessive stress on wire feed unit, resulting in
disturbances in wire feed.
Screw the snap connector of gun tightly, to avoid voltage losses on connecting surface. A loose connection will heat
gun and wire feed unit. After tightening, check that guide tube inside connector is not in contact with feed rolls.
The wire feed rolls are available with plain groove,
knurled groove and with trapezoidal groove for different
purposes.
Feed rolls with plain groove:
1. Universal feed roll for welding of all kind of wires.
2. Special feed rolls for heavy duty use.
Feed rolls with knurled groove:
Special feed roll for cored wires and steel wires.
Feed rolls with trapezoidal groove:
Special feed roll for aluminium wires.

5.3. MOUNTING AND LOCKING WIRE REEL
– Release locking nails of wire reel hub by turning locking knob
to the position OPEN.
– Put the reel at its place. Note the rotating direction of reel!
– Turn locking knob to the position LOCKED.
Check filler wire reel for no protruding parts, which could e.g. chaff against chassis or wire feed unit
door. Dragging parts could expose chassis of wire feed unit under voltage.
5.4. AUTOMATIC WIRE FEED TO GUN
Automatic wire feed makes the change of wire reel quicker. The pressure on feed rolls need not be released and
filler wire goes automatically to correct wire line.
– Make sure that the groove of feed roll matches the diameter of
welding wire used. Feed roll groove is selected by moving the
groove selection washer. Also the selector plate for changing
the feed roll groove has to be moved similarly. (see table on
page 4).
– Release the wire end from the reel and cut off the bent length.
Be careful that the wire does not spill from the reel to the sides!
groove selecting washer
– Straighten approximately 20 cm of the wire. Ensure that the wire end has no sharp edges, if necessary file
them off. A sharp edge may damage the wire guide tube and contact tip of welding gun.
– Draw a piece of loose wire from wire reel. Feed wire through back liner to feed rolls. Do not release the
pressure of the feed rolls!
– Press the gun switch or wire inch switch and feed a piece of wire through feed rolls to the gun. Ensure that
wire is in the grooves of both feed rolls!
– Hold down the switch until the wire has come through the contact tip.
Automatic feed may sometimes fail with thin wires (Fe, Ss: 0,6...0,8 mm, Al, Fc: 0,8...1,0 mm). In this case,
open feed rolls and feed the wire through manually.
5.5. ADJUSTING PRESSURE
Adjust the pressure of feed rolls with control screw, 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 on the feed rolls.
Excessive pressure causes flattening of the filler wire and damage to the coating. It also causes friction
and undue wear of the feed rolls.
5.6. ADJUSTING THE TIGHTNESS OF WIRE REEL BRAKE
Brake force is adjusted through a hole in the locking device
of reel hub by tightening/loosening the adjustment screw with
a screwdriver.
Adjust the brake force so big that the wire does not slip from
the full reel when the reel stops rotating. The need for brake
force is increased with wire feed speed.
Standard accessory: 200 mm wire reel adaptor
Make sure that the welding gun is designed for the maximum welding current! Do not use a damaged
welding gun!
5.7. RETURN CURRENT CABLE
Fasten earth clamp of return current cable carefully, preferably direct to welding piece. Contact surface of the clamp
should always be as large as possible.
Clean the fastening surface from paint and rust!
Use copper cables in your Kempoweld equipment. A too small cross-sectional area might cause overheating of
connectors and insulations.

5.8. SHIELD GAS
Handle gas bottle with care. There is a risk for injury if gas bottle or bottle valve is damaged!
For welding stainless steels, mixed gases are normally used. Check that the gas bottle valve is suitable for the gas.
The flow rate is set according to the welding power used in the job. A suitable flow rate is normally 8 - 10 l/min.
If the gas flow is not suitable, the welded joint will be sporous. Contact your local Kemppi-dealer for choosing
gas and equipment.
5.8.1. Installing gas bottle
Always fasten gas bottle properly in vertical position in a special holder on the wall or on a carriage.
Remember to close gas bottle valve after having finished welding.
Parts of gas flow regulator
A Gas bottle valve
B Press regulation screw
C Connecting nut
D Hose spindle
E Jacket nut
F Gas bottle pressure meter
G Gas hose pressure meter
The following installing instructions are valid for most of the gas flow regulator types:
1. Step aside and open the bottle valve (A) for a while to blow out possible impurities from the bottle 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 bottle 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 bottle valve slowly. Gas bottle pressure meter (F) shows the bottle pressure. Note! Do not use the
whole contents of the bottle. The bottle should be filled when the bottle 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 flow (or pressure). When regulating
flow amount, the power source should be in switched on and the gun switch pressed simultaniously.
Close bottle valve after having finished welding. If the machine will be out of use for a long time, unscrew the
pressure regulation screw.
6. CONTROL PANELS AND ADJUSTMENTS
6.1. WIRE FEED SPEED POTENTIOMETER
The wire feed speed is adjusted with the potentiometer on the front panel, see the chapter Panels. The potentiometer
has a memory scale for max. speeds of 18 m/min.
6.2. BURN BACK TIME
Different filler materials and shielding gases behave in different ways in the completion of welding. The welding
current should be selected for a burn back time suitable for the welding work.
If you try to cease welding with an unsuitable burn back time, the wire will burn in the contact tip, there will be a
too large amount of wire at the wire end, or the wire will stick at the stopping point.
Factors influencing the delay:
The requred burn back time depends a lot of the wire feed speed. For low wire feed speeds always select a short
burn back time.

1. Set the welding cycle time with the potentiometer. The pause time is adjusted automatically.
2. Press the gun switch: cycle welding is continued as long as the switch remains pressed.
7. OPERATION DISTURBANCES
The use and working environment of the equipment should be taken into consideration when planning the maintenance
of the wire feed unit. Careful use and preventive maintenance will help to ensure problem-free operation.
The following maintenance operations should be carried out at least every six months:
Check:
– The wear of feed roll grooves. Excessive wear of grooves will cause problems in wire feed.
– The wear of wire guide tubes in wire feed unit. Worn-out feed rolls and wire guide tubes should be
replaced.
– The wire guide tube in the gun should be set as close to the feed rolls as possible, but not in contact with
them. The wire must be in a straight line from the end of the tube to the feed roll groove.
– Reel brake adjustment
– Electric connections
* Oxidised couplings must be cleaned.
* Loose couplings must be tightened.
Clean dust and dirt from the equipment.
In case of problems contact your Kemppi dealer.
When using compressed air, always use proper eye protection.
In the instruction labels of filler wires, starting points for adjustment are
given. Fine-adjustment should be carried out case-specific.
1. Aluminium melts much quicker than other materials, so the burn
back time can be shorter.
2. Steel and especially flux cored wires require a longer burn back time
than stainless materials.
3. Thicker filler wires require a longer time. Also, when the wire feed
speed increases the burn back time must be extended.
4. Memory scale for potentiometer.
5. Wire inch
Welding with the 2-sequence trigger procedure
1. Switch pressed: welding starts
2. Switch open: welding stops
Welding with the 4-sequence trigger procedure
1. Switch pressed: shielding gas flows
2. Switch open: welding starts
3. Switch pressed: welding stops
4. Switch open: gas flow stops after the post gas time
Wire inch
With wire inch, wire feed motor and mechanism can be operated without starting the power source.
The filler wire can be driven into the wire feed unit and gun also by pressing the welding gun switch, but then the
power source will start and the wire becomes live, which can cause a danger of accidental contacts with surrounding
objects!
