1.3. OPERATION SAFETY

Please study these Operation safety instructions and respect them when installing, operating and servicing the machine.

Welding arc and spatters

Welding arc hurts unprotected eyes. Be careful also with reﬂ ecting arc ﬂ ash. Welding arc and spatter burn unprotected skin. Use safety gloves and protective clothing.

Danger for ﬁ re or explosion

Pay attention to ﬁ re safety regulations. Remove ﬂ ammable or explosive materials from welding place. Always reserve sufﬁ cient ﬁ re-ﬁ ghting equipment on welding place. Be prepared for hazards in special welding jobs, e.g. for the danger of ﬁ re or explosion when welding container type work pieces. Note! Fire can break out from sparks even several hours after the welding work has been ﬁ nished!

Mains voltage

Never take welding machine inside a work piece (eg. container or truck). Do not place welding machine on a wet surface. Always check cables before operating the machine. Change defect cables without delay. Defect cables may cause an injury or set out a ﬁ re. Connection cable must not be compressed, it must not touch sharp edges or hot work pieces.

Welding power circuit

Isolate yourself by using proper protective clothing, do not wear wet clothing. Never work on a wet surface or use defect cables. Do not put MIG gun or welding cables on welding machine or on other electric equipment. Do not press MIG gun’s switch, if the gun is not directed towards a work piece.

2.4. ASSEMBLY OF MIG EQUIPMENT

Kempomig power source:

Read paragraph INSTALLATION in the operation instructions (1922430E) for the Kempomigpower source in question.

Feed 420R and Feed 120R wire feeding equipment:

1. Mount the wire feeder onto the shaft which is on top of the power source. The shaft must have plastic insulation / bear bushing.

2. Mount control cable of interconnection cable and welding current cable to connectors on the rear wall of Feed 420R. Select the MIG gun´s polarity (+ or –) according to welding wire you are using.

3. Mount the MIG gun to EURO connector on the front wall of the Feed 120R. 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 wire feed disturbances.

4. If you mount the Feed 420R onto boom, see that the wire feeder unit´s chassis is without galvanic contact to boom.

5. Max. wire feed speed When the unit is delivered the max. wire feed speed is 18 m/min, which is enough for most welding works. If you need a higher speed, you can increase the max. wire feed speed to 25 m/min by replacing the gear wheel on motor shaft to a bigger one as well as through change of jumper on the control card. The big gear wheel (D40) belongs to delivery kit of the Feed 120R.

When necessary speed is changed according to following:

8 7 6 5 4 3 2

25 m/min 18 m/min

JUMPER BLOCK

A001

– Open side plate and move JUMPER BLOCK´s ﬁ rst coding piece on control card A001 to

point 25m/min.

– Open tightening lever (20). Remove lower feed rolls (21). Release screw (23) and its washer.

Remove gear wheel D28 (24) from motor shaft.

20 25

21 23 24 21 22 25 22

– Loosen screws (25) (3 pc) 1 twist. Mount the D40 gear wheel onto motor shaft. Screw the

screw (23) with its washer back.

– Put feed rolls (21) back to their axles, however don´t fasten yet fastening screws of the feed

rolls (22).

– Lift the motor so that the tooth gap between gear wheel and both lower feed rolls is approx.

0,2 mm.

Kempomig Feed 420R, 120R / 0429 – 9

– Tighten screws (25). Check gear teeth gaps, when necessary put the motor into a better

position. Screw on the mounting screws of feed rolls (22).

Too small a gap between gear wheel and feed rolls will overload motor. Too big a gap for its part might cause too rapid wearing for teeth of feed rolls

and gear wheel.

– Mounting of push-pull gun´s synchronizing unit SYNC 400 and gas guard GG is described in

the mounting instructions delivered with the units.

2.5. INSTALLATION

2.5.1. Wire feed mechanism (Feed 120R)

Wire feed rolls are available with plain groove, knurled groove and with U groove for different purposes.

Feed rolls with plain groove: Universal feed roll for welding of all kinds of wires Feed rolls with knurled groove: Special feed roll for cored wires and steel wires Feed rolls with U groove: Special feed roll for aluminium wires

Wire feed rolls have two grooves for different ﬁ ller wire diameters. Correct wire groove is selected by moving selecting washer (28) from one side to another in feed roll.

Feed rolls and wire guide tubes have colour codes in order to make identiﬁ cation easier (see table on page 8).

feed rolls

colour ﬁ ller 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) yellow 1.4, 1.6 and 2.0 (1/16 and 5/64) black 2.4 (3/32)

guide tubes

colour ﬁ ller wire ø mm (inch) orange 0.6-1.6 (0.024-1/16) blue over 1.6 (over 1/16)

In delivery Feed 120R is equipped with red feed rolls with plain groove and with orange wire guide tubes for welding ﬁ ller wires of 0.9-1.2 mm (0.035”, 0.045” ja 0.052”).

2.6. MOUNTING OF MIG WELDING GUN

In order to ensure trouble-free welding, check the operation instructions of gun used that wire guide tube and contact tip of gun are according to manufacturer´s recommendation, and suitable for wire diameter and type in question. Too tight a wire guide tube might cause for wire feeder unit a bigger stress than normally as well as disturbances in wire feed.

Screw snap connector of gun tight to avoid any voltage losses on connecting surface. A loose connection will heat gun and wire feeder unit.

2.7. MOUNTING AND LOCKING OF WIRE REEL (ACCESSORY)

LOCKED OPEN

10 – Kempomig Feed 420R, 120R / 0429

– Release locking nails of wire reel hub by turning locking knob a quarter of a round. – Mount the reel at its place. Note rotating direction of reel! – Lock the reel with locking knob, locking nails of hub remain in outside position and will lock the reel.

Check the ﬁ ller wire reel that there are no parts sticking out which could e.g. chafe against chassis or door of wire feeder unit. Dragging parts might expose chassis of wire feeder unit under voltage.

2.8. AUTOMATIC WIRE FEED TO GUN (FEED 120R)

Automatic wire feed makes change of wire reel more rapid. In reel change the pressure of feed rolls need not be released and ﬁ ller wire goes automatically to correct wire line.

– Make sure that groove of feed roll matches the diameter of welding wire used. Feed roll

groove is selected by moving the groove selecting washer (28).

– Release the wire end from reel and cut off the bent length. Be careful that the wire does not

spill from the reel to sides!

– Straighten the wire at a length of about 20 cm and see that its end has no sharp edges (ﬁ le off

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 reel. Feed wire through back liner to feed rolls. Do not

release pressure of feed rolls!

– Press the gun switch and feed a bit 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, Ss: 0,6...0,8 mm, Al, Fc: 0,8...1,0 mm).

In case open feed rolls and feed wire manually.

2.9. 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.

Excessive pressure causes ﬂ attening of the ﬁ ller wire and damage to the coating. It also causes undue wear of the feed rolls as well as friction.

2.10. ADJUSTMENT OF TIGHTNESS OF WIRE REEL BRAKE

(ACCESSORY)

Kempomig Feed 420R, 120R / 0429 – 11

Brake force is adjusted through hole in locking device of reel hub by screwing the control screw (41) with screwdriver.

Adjust brake force so high that the wire does not become too loose on the reel so that it would spill from the reel when the rotation of the reel stops. Need for brake force is increased with increase of the wire feed speed.

Since the brake loads the motor for its part, you should not keep it unnecessarily tight.

2.11. GROUND CABLE

Fasten earthing clamp of ground cable carefully, preferably direct to welding piece. Contact surface of clamp should always be as large as possible.

Clean the fastening surface from paint and rust!

Use 50 mm

cables in your MIG equipment. 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! Never use a damaged welding gun!

2.12. 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 ﬂ ow rate is set according to the welding power used in the job. A suitable ﬂ ow rate is normally 8 - 10 l/min. If the gas ﬂ ow is not suitable, the welded joint will be sporous. Contact your local Kemppi dealer for choosing gas and equipment.

2.12.1. 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 ﬁ nished welding.

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 ﬁ lled 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 ﬂ ow

(or pressure). When regulating ﬂ ow amount, the power source should be in switched on and the gun switch pressed simultaniously.

Close bottle valve after having ﬁ nished welding. If the machine will be out of use for a long time, unscrew the pressure regulation screw.

3.12. FEED 420R ERROR CODES

By every start possible error states in equipment are checked. If an error state is found, the error in question is shown with an E text appearing in the panel display.

Here are some error codes:

E.09: Overloading of wire feed motor, which can be e.g. due to blocked wire guide tube of gun, or too sharply bent gun cable.

E.12: The welding is prevented because the shielding gas control of the gas guard GG 400 has released.

The error codes disappear by following start, if reason of the error code is eliminated.

4. ACCESSORIES

4.1. SYNCHRONIZING UNIT SYNC 400

By means of Sync 400 you can connect the push-pull gun to the Feed 420R wire feeding control unit. Push-pull gun is most commonly used for feeding of aluminium wires.

5. SERVICE AND OPERATION DISTURBANCES

The amount of use and working environment should be taken into consideration when planning the frequency of maintenance of Feed 420R and 120R. Careful use and preventive maintenance will help to ensure trouble-free operation.

Following maintenance operations should be carried out at least every six months: Check:

– Feed roll grooves. Excessive wear of grooves causes wire

feed problems.

– Wire guide tubes. Badly worn feed rolls and wire guide

tubes should be discarded.

– Wire guide tube in the gun should be set as close to the feed

rolls as possible and the wire must follow a straight line

from the end of the tube to the groove of the feed roll. – Reel brake adjustment. – Electrical connections: * Oxidized couplings must be cleaned * Loose couplings must be tightened Clean dust and dirt from the equipment.

When using compressed air, always protect your eyes with proper eye protection.
