2.5 OPERATION AND USE OF CONTROLS
See the page for Kempoweld PANELS and COOLING UNIT.
2.5.1 Main switch (S1)
In zero position all control and welding current circuits of the equipment are dead (without
voltage). In position I the control circuits of the machine become live (get voltage). The
primary and welding circuits are dead, if the welding mode has not been started with the gun
trigger.
NOTE! Always switch on and switch o the machine from the main switch. Never use the mains
plug for switching on or switching o the units and equipment!
2.5.2 Adjustment of welding voltage,
Table of adjustments, switch positions:
coarse control fine control open circuit voltage
1 / 4 1 / 10 – 10 / 10 15.5 – 18.2V
2 / 4 1 / 10 – 10 / 10 18.6 – 22.5V
3 / 4 1 / 10 – 10 / 10 23.1 – 29.3V
4 / 4 1 / 10 – 10 / 10 30.4 – 41.6V
The welding voltage is adjusted with two turn switches. The S2 is the 4-step switch for coarse
control, where voltage value of each step can be ne-adjusted with the 10-step switch S3.
2.5.3 Pilot lamps
Pilot lamps of the machine report about electric function:
The green pilot lamp H1 indicating that the machine is ready for operation is always lit, when
the machine is connected to mains voltage and the main switch is on position I.
The yellow pilot lamp H2 is lit, when thermal protection of the welding circuit has released
due to overheating. The protection releases if the power source is continuously loaded over
rated values or the cooling air circulation has been obstructed.
2.5.4 Control fuse (F1)
On the rear plate of the power source the fuse (F1) 8 A delayed is the short-circuit protection.
Use the fuse size and type according to markings. Damage caused by a wrong type fuse is not
covered by the guarantee. If the fuse is blowing again, send the unit to service.
2.5.5 Adjustment for arc roughness
Arc roughness is adjusted by connecting the return current cable to the applicable one of the
two dix-connectors on the front plate.
The connector marked with shorter symbol gives a rougher arc, which is used for welding
of thin sheets and ferrous metals by 0.6 – 1.0 mm wires and especially with CO²shielding
gas. The connector marked with longer symbol is suitable for thicker wires and especially for
aluminium and stainless materials. The most suitable roughness is, however, most dependent
on the welding case. You will nd the best position by testing the dierent positions.
2.5.6 Operation of cooling fan
The cooling fan on the rear plate of the Kempoweld 3200 equipment is started and stopped
according to use. The cooling fan is controlled by the gun trigger and control circuits. The
cooling fan is started after ca. 15 s after weld start and stopped after ca. 10 min after weld end
or release of the overheat protection.
NOTE! Do not switch o the unit with the main switch before the cooling fan has automatically
stopped. By open circuit the cooling fan does not get started.

2.5.7 Accessory drawer
In the accessory drawer in the cover part of the unit are by delivery the plastic guide tubes
needed for welding of aluminium and stainless steels. In the drawer are also the screw and the
insulation bushings needed for locking of rotation of the wire feeder Kempoweld WIRE 400.
2.5.8 Adjustment for wire feed
The wire feed is adjusted from the potentiometer on the control panel of the wire feeder unit
Kempoweld WIRE 400. The adjustment has been described in the operation instructions of the
wire feeder unit.
2.6 VOLT / AMPERE METERING UNIT MSD1
For the mounting of the MSD-1 remove the cover plate on the front panel of the unit.
The connector of at cable fastened to the cover plate is connected to the corresponding
connector of the MSD-1. From the metering unit you can with lever switch select momentary
display for either voltage or current. By open circuit only voltage value is displayed, because
there is no welding current present.
The voltage value is the voltage between the unit´s welding connectors or terminal voltage.
The value of the open circuit voltage has not very much importance for the welding, so that
the display of the metering unit is adjusted according to the welding situation. The display
of the open circuit voltage diers 2 – 3 V from the true voltage. During welding the terminal
voltage is varying and the arc voltage diers from the terminal voltage due to cable etc. losses.
Accuracy of voltage true value in respect to real value is ±4,0%, ±0,2V by welding values
according to the norm.
Accuracy of current true value in respect to real value is ±2,5 %, ±2 A.
The metering unit does not show wire feed values.
The MSD-1 does not need any calibration in the Kempoweld power source.
The switch positions: V = voltage display, A = current display.
2.7 COOLING UNIT
Kempoweld 3200W power source has inbuilt cooling unit.
2.7.1 Installation of cooling
The cooling unit is connected to the gun by means of water hoses, which are mounted to the
wire feeder unit. The interconnection cable contains also the water hoses, which are mounted
to the gun through the wire feeder unit without any extension parts. See operation instruction
for Kempoweld WIRE feeders.
Before connection check that in the hoses are no dirt, metal powder, rubber waste etc. The
connectors for hoses and cooling unit are marked with red or blue identication rings or
spots. Blue is colour for water supplied from cooling unit to gun and red is colour for water
returning back from gun to cooling unit.
The cooling unit´s tank is lled with 40 % antifreeze according to British Standard BS3151. If
the circumstances do not require frost resistance, you can use a more dilute mixture, or some
other mixture, of which you have good experriences.
Tank volume is ca. 3 litres, volume of gun and interconnection cable is 0.3 – 1.5 litres. Filling of
hoses takes 5 s – 3min time. Check the return ow to the tank. Before lling check that tank,
cooling water, pouring tank etc. are clean, and that there is no metal powder, waste etc.

EN
NOTE! If the water does not start circulating, see paragraph Operation disturbances: “The water does
not circulate ... etc.
Do not let any waste and dirt into the water circulation! Check lling volume before starting to weld!
Use the cooling liquid according to recommendations, or the one you know as good beforehand.
Watch over liquid material´s quality and possible sediments in hoses of the gun.
Do not swallow cooling liquid. If somebody has swallowed the liquid, take him immediately to
medical care. Avoid contact with skin and eyes, wash the liquid from your skin with clean water.
2.7.2 Operation switches
In zero (O) position of the power source´s main switch also all operations of the cooling unit
are stopped.
Cooling unit´s main switch O / I
The electric supply for the pump motor is switched on by main switch key O / I, where the
pilot lamp indicates the standby state I. In zero (O) position of the main switch the pump
motor cannot get started, but the switches and pilot lamps are operating.
Fuse (F2)
The fuse on the front wall of the cooling unit is short-circuit protection. Use the fuse size and
type according to markings. If the fuse is blowing again, send the unit to service.
Selecting switch for gun’s cooling mode (Sw1)
The Kempoweld equipment are suitable to be used with both air- and water-cooled guns.
Select cooling mode and correct use and protection functions with switch on the cooling
unit´s panel.
If your choice is GAS, but you are using water-cooled gun, no protection is operating. The pilot
lamp is illuminated in position Iof the cooling unit´s main switch. However, the control does
not start the pump.
The wrong choice will destroy the gun in short time!
If your choice is (water), but you are using air-cooled gun, the pump gets started by
pressing on the trigger, if the cooling unit´s main switch is in position I.
Test switch (Sw5)
By TEST switch on the panel of the cooling unit you can circulate water without starting
welding. It is used for lling the gun and interconnection cable with cooling water before
starting welding. By disturbance situations you can always test the water circulation. Always
check entry of return water into the tank before welding!
Pilot lamps
Pilot lamp for overheating (Hw4)
If the cooling water in the tank is overheating, the thermal protection will stop the power
source. Operation of the cooling unit is continued for ca. 5 – 7 min automatically. The pilot
lamp will switch o after the water in the tank has cooled down, after which the welding will
start from the gun triggering.
Pilot lamp for lacking liquid pressure (Hw3)
If the pump does not step up sucient supply pressure, e.g. when the water is running out
or by disturbances in the pump, the whole equipment will stop after ca. 5 s and the red pilot
lamp illuminates. Check the equipment like by the installation. See paragraph for OPERATION
DISTURBANCES.
Operating control
The water circulation gets automatically started, when you are pressing on the gun trigger.
The post-circulation of water will continue for ca. 5 – 7 min. after the weld end. The time is
always counted from the latest trigger release.

3. OPERATION DISTURBANCES
By the operation or functional disturbances take the measures according to the following list.
If the disturbance cannot be eliminated, check the equipment according to the paragraphs
Installation and Maintenance, and take contact with Authorized Kemppi repair workshop.
The pump does not get started by test switch:
• check the fuse on the front plate of the cooling unit
• check the fuse on the rear plate of the power source
• check position for cooling mode selecting switch
• check positions for main switches
The water does not circulate by lever switch:
• check the tank lling volume
• disconnect the connector for the return water hose of the gun from the rear wall of the
cooling unit and use thet test switch
If the water is pumped, close the connector and run again by the test switch
A good tip: Blow compressed air into the tank; closing the lling opening by hand is enough.
The water is pumping, but does not return back to the tank or the return ow is
weak:
• lling of interconnection cable can take several minutes
• if you have lifted the gun or interconnection cable for the lling time many meters
higher than the power source, the lling will happen considerably slower. Fill the hoses
on the oor position.
• check the whole owing line connector by connector
The water is pumping, but during welding the red pilot lamp for the water
pressure is lit and the equipment is stopped:
• check the cooling water volume and return ow to the tank
• in the system are air bubbles or leakages, especially check the connections of the cooling
unit.
• the pressure switch set value (ca. 1 bar) is unsuitable for the gun you are using:
1. Open the side plate. In the middle at the upper end of the pressure guard connected to
the pump is the adjusting screw for limit value.
2. Use the pump during the adjustment by the test switch.
3. After ca. 5 s use twist the screw carefully until the pilot lamp is switched o.
4. Check the result by welding.
5. If the adjustment and checkings do not eliminate the disturbance, take contact with the
Authorized Kemppi repair workshop.
During welding the yellow pilot lamp for overheating is lit and the equipment is
stopped:
• release the trigger. When the lamp is switched o, the operation has been reset
automatically
• check if the gun is suitable for power you are using
• check condition of connectors and connections in the welding current circuit
