2.6.2. Installing wire reel
1. Install wire reel so that the hole in the reel is aligned with the pin on the reel
holder. Use reel adaptor, if necessary.
2. Release the locking claws of wire reel locking by turning the latch 45 degrees.
3. Push the reel into its place. Note! Check the reel rotation direction.
4. Lock the reel by turning the locking latch.
Note! Check that the wire or wire reel does not touch the equipment body!
2.6.3. Installing welding wire
Do not direct welding gun to yourself or to persons around you!
Before installing welding wire, check that feed rolls, wire conduit and contact tip are
suitable for the wire.
1. Install feed rolls, check that the right groove is in the wire feed line. The
groove can be changed by changing the position of the adjusting plate.
2. Check that there are no sharp edges on wire end, round off if necessary. Sharp
edges may damage wire guide and wire conduit. Watch out that the wire does
not get loose!
3. Push the wire through wire guide tube into feed rolls. Do not release the
pressure of the feed rolls.
4. Use wire inch switch to make the wire roll into the gun. You can also feed the
wire to the gun by pressing the gun switch and pushing the wire slightly until
it automatically rolls through the feed rolls into the gun. Note! Check that the
wire runs in the grooves of the both feed roll pairs!
5. Adjust the pressure of wire feed rolls with adjusting screw. The press force to
the feed rolls is suitable when wire can be slightly restrained with fingers when
coming out of wire conduit, without feed rolls slipping. Note! If the pressure
is too high, filler wire flattens and its coating may fall off. Feed rolls wear out
more quickly and friction increases.
6. Adjust the wire reel braking force by turning the adjusting screw in the middle
of the locking latch with a screwdriver. Note! To avoid over-loading wire feed
motor, do not tighten too much.

2.7. Shielding gas
Handle gas bottle with care. There is a risk of injury if gas bottle or bottle valve
gets 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.
2.7.1. 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 installation 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 impu-
rities 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.
See 2.5.2. Main parts of wire feed mechanism. 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.

3. OPERATION
Welding in places presenting an immediate fire or explosion hazard is forbidden!
3.1. Welding processes
3.1.1. MIG/MAG -welding
In MIG/MAG-welding the filler wire is feeded through welding gun wire conduit to the
welding joint. Welding current strenght and wire feed speed are chosen according to the
characteristics of the work piece to be welded. The values are selected and adjusted with
separate potentiometers.
3.1.2. Synergic MIG/MAG -welding or 1-MIG
In synergic MIG-welding the parameters are determined by the wire feed speed set-
ting. This means that in the synergic process, welding power can be adjusted using one
potentiometer only. In the beginning of the process, a synergic curve suitable for the
filler wire and gas must be chosen, to make the parameters adjustable from wire feed
potentiometer.
3.1.3. Synergic pulsed MIG-welding
In synergic pulsed MIG-welding the welding current is cut in pulses, so that the filler
material can be transferred to work piece controlled and without spatter. In the synergic
process, welding power can be adjusted using one potentiometer only. In the beginning
of the process, a synergic curve suitable for the filler wire and gas must be chosen, to
make the parameters adjustable from wire feed potentiometer. The pulse parameters of
power source change automatically when wire feed speed is changed.
3.2. Special functions
3.2.1. Welding gun trigger 2-sequence function
Gas flow and wire inch start, when the gun switch is pressed and stop when the switch
is released.
3.2.2. Welding gun trigger 4-sequence function
Gas flow starts, when the gun switch is pressed. When the switch is released, wire inch
starts and welding begins. When the gun switch is pressed again, wire inch stops and
when the switch is released, gas flow stops.
3.3. Operation functions
See also 2.4. Installation and main parts.
3.3.1. Wire feed unit and function panel
Before starting welding, welding settings suitable for the work piece are chosen in
function panel. See 3.1. Welding processes. When needed, the settings can be adjusted
on function panel. The main functions of the ML-panel are presented on the following
page.

Compensating cable length
With this function the voltage losses with long interconnecting cables and dif-
ferent welding guns can be compensated. Cable compensation is adjusted as
follows:
If interconnecting cables are not used, set cable compensation at position zero.
If the zero position does not operate wanted, check the adjustment as follows:
1. Select arc length at = CAL, which corresponds to normal arc length.
2. Weld at required power level.
3. Select a suitable arc length with the potentiometer.
4. Check adjustment range of arc length by adjusting arc length -9...0...9
5. When needed repeat the procedure.
Cable compensation is adjusted for each cable and MIG welding gun combination only
once.
Control of welding dynamics
MIG and MMA welding dynamics are adjusted with the same potentiometer.
When you adjust welding dynamics the adjustment value -9...0...9 is shown in
display V, which otherwise shows set value/welding voltage. Value of dyna-
mics is shown in display still for approx. 3 s after stopping the adjustments.
Control of MIG/MAG welding dynamics
With control of MIG/MAG welding dynamics you can influence on how stable the arc
is and how much spatter there is. With this control you can also optimize the welding
result for wire type and shielding gas mixture you are using.
-9...-1 Softer arc. Object: minimizing spatter
0 Recommendable basic setting for all wires
1...9 Harder arc. Object: e.g. maximizing stability of the arc on short circuit and
welding of steel with 100 % CO2 shielding gas (settings 7...9).
Control of SYNERGIC MIG welding dynamics
In SYNERGIC MIG the control of welding dynamics is optimized for wire type you are
using. With this control you can influence on stability of arc and how much spatter there
is.
-9...-1 Softer arc. Object: Minimizing spatter
0 Recommendable basic setting
1...9 Harder arc. Object: e.g. maximizing stability of the arc on short circuit
NOTE! The control range for MIG welding dynamics -9...0...9 is a relative range accor-
ding to wire and is different from control range -9...0...9 for dynamics of normal MIG/
MAG welding.

PROMIG 200ML/0509 – 12 © KEMPPI OY
Shape of arc in SYNERGIC PULSED MIG:
In SYNERGIC PULSMIG the control for welding dynamics has an influence on shape
of pulsed MIG arc.
-9...-1 Wider pulsed MIG arc. Object: e.g. welding of square butt preparation
0 Recommendable basic setting
1...9 More narrow and better directed arc. Object: e.g. fillet weld seams of thin basic
materials
Control of MMA dynamics
With control of MMA dynamics you can influence on arc in different situations.
When you make the arc harder, blow and at the same time spatter is increased.
-9...-1 Softer arc. Object: Minimizing spatter in welding at upper end of recommen
ded currents for electrode.
0 Factory setup. Normal setting for all electrode types.
1...9 Harder arc. Object: e.g. cellulose covered electrodes (9) and thin stainless
electrodes in welding at lower end of recommended currents for electrode.
Shielding gas flow regulation
Shielding gas flow can be regulated with a flow regulator 5....25 l/min. The display is
calibrated for Ar CO2 mixed gas (75% Ar, 25% CO2). With other gases the meter error
tolerance remains within ±10% compared with real flow. This is reached only when the
angle of deflection is smaller than 15° in regard to vertical. Regulate the meter always
having the unit is in vertical position. Gas flow is shown in the centre of swimmer.

feed rolls. See 2.9. Filler wire materials and equipments and 4. Maintenance.
Wire feed is stopped.
Wire feed pressure is too high or too low.
 Check wire reel adjusting screw, feed rolls, adjustment plate and gear wheel.
See 2.4.3. Main parts of wire feed unit and 2.8. Filler wire materials and equip-
ments.
Power source overheat signal lamp is lighting.
Power source is overheated. See 3.2. Signal lamps and funtion panel.
 Check there is enough free space behind the machine for cooling air circula-
tion.
For further information and assistance, contact your nearest Kemppi service work-
shop. If an error code appears on function panel view, please also note the code number
(Err+number).
4.4.1. Error codes
By PROMIG unit check by each start, if there are error states in the equipment; in case
error states are observed, the error state in question is shown by means of Err textes
appearing on (wire feed) display of panels.
Error codes are among others the following:
Err 1: PROMIG has gone over to MMA welding, though you have already selected
MMA welding on power source panel.
Err 2: You are pressing on start switch of gun, when data transmission between
PROMIG and PRO is broken (defect in control cable or in connector), or you
are pressing on gun switch, when MMA welding has been selected on control
panel of power source.
Err 4: You are pressing on start switch of gun and selecting switch S12 for cooling
mode of gun is in liquid position and you have forgotten to switch-on the PRO-
COOL cooling unit or you have forgotten to connect it to equipment.

Err 5: PROCOOL cooling unit has stopped welding. Reason can be break of supply
voltage from PROCOOL, pressure of liquid circulation doesn´t arise or tempe-
rature of cooling liquid has arisen too high.
Err 6: Wire feed unit has stopped welding in liquid position of selecting switch S12
of air/liquid-cooled gun for PROMIG, because data communication to cooling
unit is broken (defect in intermediate cable or in connection).
Err 7: Selecting switch S12 of air/liquid-cooled gun for PROMIG is in air position,
PROCOOL is switched-on and start switch is pressed down. Purpose of opera-
tion is to prevent the liquid-cooled gun from being destroyed, if the selecting
switch S12 for air/liquid-cooling is in wrong position.
Err 8: Liquid-cooled PMT gun is overheated.
Err 9: Overload of wire feed motor, which can be caused e.g. by blocked wire guide
of gun or by gun cable, which is too much curved.
Err 10: Operation of thermal release of PRO power source has stopped welding.
Err 11: You try to use the PMT gun, when their use is prevented with the 5. jumper
operation.
Err 12: Welding has been stopped, because so called door switch or gas guard has ope-
rated (operations need extra mountings to standard unit).
Eliminate the error codes as follows:
Error code Err 1 is eliminated when PROMIG wire feed system is set into MIG state.
Blinking of error codes Err 2-4 ends automatically within 5 s, if the trigger is not
pressed down.
Eliminate the reason of error before next start.
Blinking of error codes Err 5-12 ends by next start, if the reason of error code has been
eliminated.
